Hello everyone. I have been asked MANY times about the amazing kit Chris Johnson used on Rihanna's 2011-2012 tours. So I figured I'd post a bit about the kit for my gearheads. :-) 
     The foremost feature of this rig is a customized Yamaha Hex rack designed by legendary drum tech Chris Achzet. Achzet designs the sickest racks in the business. Period. Whether using parts from rack manufacturers (DW/Gibraltar/Yamaha/Pearl), or using his own custom designed systems Chris Achzet's work is unparralled. To see some of the most amazing rack designs on the planet please visit L.A.D.S (Los Angeles Drum Service)
This rack was so much fun to build, and so easy to pack up super quickly.

​The drums CJ uaed for thr 2011/2012 tours were Black stain Yamaha Oak Custom. The kit layout is as follows:
Chris Johnson uses Remo drumheads.
 8” tom (Remo Clear Emperor Top/Clear Ambassador Bottom)
10” Tom (Remo Clear Emperor Top/Clear Ambassador Bottom)
12” Tom (Remo Clear Emperor Top/Clear Ambassador Bottom)
16” Floor Tom (Remo Clear Emperor Top/Clear Ambassador Bottom)
18” Floor Tom with an open bottom head and a PS3 C2 w/ Clear Dot so it acts like a Gong Bass Drum. I cut out the bottom head with an exacto knife leaving only a thin rim of head attached to the collar. This allowed me to put the bottom hoop on, while still getting a concert tom vibe, and protecting the bearing edge.
22” Kick on stage left (Remo Clear PS3)
24” Kick on stage right (Remo Clear PS3)
CJ's  main snare is a 5 1/2” x 14” Manu Katche with an Emperor X on top. Tuned moderately tight. 
His second snare is a 7” x 14” Yamaha Oak Loud series snare with an Emperor X on top. Although I had to use a little gaff tape on each DT20 trigger to make sure it stayed put, I also put two tape tents on the this drum to create what I like to call the "Superstition Snare". This drum was tuned super super fat.
His 3rd snare is a 13” Musashi with a Coated Emperor, and I tuned it gunshot tight.
We use a mixture of Yamaha and DDrum Triggers for gates, and samples
- The 8”, 10”, and 12” toms have Yamaha DT10 triggers to control the gates
- The 16” and 18” Floors have DDrum DST triggers for gates, and on the 18” there is an extra DDrum DST for samples
- The three snares have Yamaha DT20 triggers for samples
- The Bass Drums have Yamaha DT20 triggers for samples
- There is an Yamaha TP100 Tom pad on his left, and a Yamaha XP100T Tom Pad on his right for samples
The triggers are mapped through an Alternate Mode Turbo KAT 4.5 Trigger controller which also has samples assigned to its 10 pad surface.
CJ uses the FP9310 or the new FP9500C Bass Drum Pedals
His Sabian Cymbal set-up left to right are:
13” Sabian Mini-Hats on a Yamaha Remote Cable Hi-Hat
14” Sabian Evolution Hi-Hats
22” Sabian Legacy
10” Sabian HHX Splash
18” Sabian HHX Evolution Crash
  6” Sabian AAX Splash
12” Sabian HHX Splash
19” Sabian HHX Xplosion
17” Sabian AAX Xtreme Chinese
20” Sabian HHX O-zone Crash

Chris uses Vater 3A wood Tip

Hello everyone. Here's a tip for making 8" toms rock. While I am an aficionado of using a fourth interval from top head (tonic) to bottom head( perfect 4th above) this tuning can make an 8" Tom sound a bit bongo like at higher tensions. To avoid this, I tune the 8" Tom to a minor 3rd interval from top head (tonic) to bottom head (minor 3rd above). Not only does this warm up the sound of the drum, but it adds a natural bend down in pitch. A drop if you will. It adds an ingratiating leading quality to the start of a big Tom fill. This interval also well on floor toms when you that little bit of whang, but do not want to sacrifice the quality of the sound hitting the mic.

All right all right. The time has come for part B of my tip for reducing unwanted snare buzz. Beyond the causes of snare buzz discussed in part A, the most common cause of snare buzz is sympathetic vibrations from the other drums in your kit. While it is next to impossible to get rid of all sympathetic vibrations from your other drums, it is possible to limit the influence of vibrations by tuning your toms (and even your Bass drum) around your snare. Take for example a standard five piece kit w/ 3 toms. By choosing good tuning intervals between the toms, you can create tuning "spaces" in between the tom's pitches where you can "fit" your snare's pitch. For example lets start with a five piece kit with a 10" Tom, a 12" Tom, and a 16" Floor Tom. As a basis, my preferred interval between a 12" Tom, and a 16" Floor Tom is a perfect 5th or what I like to call the "My Girl" interval (if it's a 14" I tend to use a perfect fourth). Then I will usually make the interval between the 10" and 12" Tom a major third. An example using the key of C would be 16"=C, 12"=G, and 10"=B (14",12"=G, and 10"=B). For those who like a low tension tuning on their snare drum, that gives you a wide range between the 16" (Tonic/C) and the 12" (perfect 5th/G) in which to tune your snare. For those who prefer a higher tension snare tuning you can tune it to an A right between the 12"(G), and the 10"(B) or to a D above the 10". Again these are just examples to give you an idea of how to create spaces in your Tom tunings in order to avoid snare buzz. None of these intervals are hard and fast rules. There is always some give and take between"where the drum sounds best/where you like it" and the intervals you choose. Just remember, the next time you have excessive snare buzz, check to make sure your snare is NOT tuned to the same pitch as any of your other drums. Also be reminded that 1/2 step intervals can be just as troublesome for snare buzz. Tune on fellow drummers.

     A common issue for ALL drummers is getting rid of unwanted snare buzz, be it a live setting, or the recording studio. While you want your snares to vibrate freely for the best “snare” sound possible, too much unnecessary buzz is a drag. Whether it’s rattle from a kick drum hit, or sympathetic buzz from a ringing tom, how you control snare buzz can make you a friend or foe to an audio engineer getting drum sounds. There are several tips I will recommend here for solving this problem, but none is as fundamentally important as centering, and leveling your snares. Centering, and leveling the snares not only reduces snare buzz. it also increases snare sensitivity which in turn makes the snare drum sound, and play better.
     Try this: Release your snare strainer (ie turn off the snares), then lift the drum up to eye level. As you look at the snares through the slot that allows the snares come through the bottom hoop, take notice of how they hang. Ideally you will want your snares to hang “level” with themselves, and perfectly horizontal on both ends compared to the drum. For example, much like horizontal leveling of a picture frame on a wall compared to the ceiling trim so should your snare ends be horizontally “level” with the bottom edge of your snare drum. Next turn your snares back on, and flip the drum over onto its top so you are looking at the snare side of the drum. Are your snares centered, and even? By centered I mean that each end of the snares is equal distance from the edge of the drum. By even I mean that each end is horizontally “even” with the edge of the drum. If not, your snare wires become unevenly tensioned when you tighten them leaving one side tight, and the other side loose. Hence snare buzz.
      To properly center the snare wires, pre set your strainer to be engaged at a light tension. Next, rest the drum upside down on a flat surface. From here lightly release each side of the snare wires from the strainer, and butt clamps. Center the snares, and then tighten the string/strap on the butt side. Then while keeping the ends of the snares even, and centered, tighten the string/straps on the strainer side. With the drum still upside down begin to tighten the strainer to make sure your wires stay straight. Fine tune for perfection, and voila centered snares. Very often this act will level the snares pretty well. Then fine tune in little increments, as the act of leveling is a test of patience, and precision. Little movements also help preserve centering. You may have to try several times to get it perfect, but the time spent on this matter is well worth it.

All right all right. It's about time! First things first. I love teaching people how to set up and tune drums. The smile on a drummers face when he or she hears their kit sound better than it ever has, AND it was by their own hand. . . ? Now that is a beautiful thing to behold. With this in mind, I will be posting tuning tips, and tricks on this page regularly in hopes that all drummers, and tuners of drums find them useful.

"Resetting an old head"
A common practice when you put on a new drumhead is to stretch the head with your hand after it's first few rounds of tightening. Once at a fair degree of tightness (to avoid overstretching of a loose head) just place your palm at the drums center and push gently. In addition, you could use the butt of one's palm to stretch the edge of the head as well. Anchoring your finger's to the outer edge of the hoop, press the butt of your palm (or your thumbs) along the bearing edge and then stretch lightly. Do this all the way around the drum. Makes sense right? Stretch all areas of a new head to ensure even tuning. When your heads are old, however,  this method is a great way to "re-awaken" the mylar from it's stretched state. Mylar hardens over time. By stretching at the center and edges, it massages the mylar fiber and opens it up a bit. Once you have stretched the old head a little bit, pick up the drum and give it a kiss in the vent hole. (ie: press your lips to the hole and blow.LOL!) If there are multiple vents, cover them with your fingers while blowing into the vent of your choice. The drum heads should expand upward/downward essentially "re-seating" the head. This will not only liven up the drums sound, but you will immediately be able to hear which lugs are truly out of tune with the others.

"The Lug Below"
Have you ever been tuning a drum where one lug doesn't seem to change in pitch no matter how much you tighten or loosen it? Often times this is a sign that the lug directly across from the one you are tuning is out of balance as well. However, this doesn't always fix the issue. If it does not, the problem lies in the lug (tension rod) directly below the one you are tuning. After resetting the head via tip # 1 (if you R not mid-show mind you), tighten (or loosen) the lug below about 1/8th of a turn. You will be surprised at how little of a turn can make a massive difference. Then check your top tension rod for balance and voila. Tuned drum.

"Soft Fuzzy Balls"
Often times when recording toms (especially floor toms and large suspended toms) you will encounter unwanted ringing or crosstalk coming from the drum. The ringing is caused by other drums and their stands vibrating in sympathy with rest of the kit. SOLUTION: Drop one, or two two stretched out cotton balls into the drum. They will act as a natural gate/ mute for the bottom head, and the effect the drum's attack is minimal. MAKE SURE TO STRETCH THE COTTON BALL OUT A BIT. Make it lok like a cloud. Not too big, but enough to disperse the weight of the ball. You want the cotton to sit quietly, versus bouncing around like popcorn. Alone they are usually sufficient to mute the crosstalk. For the worst cases, use in conjunction with a little tape tent on the bottom head.
"Getting Balanced Before You Lose Your Head"
When changing a head, I find it very useful to first retune, and rebalance the drum BEFORE YOU TAKE OFF THE HEAD TO BE REPLACED! A drum is a tensioned instrument, therefore bottom head tension affects top head tension and vice versa. They both affect the shell. If the drum is balanced when you remove the one head, minor imperfections in pitch from lug to lug become much more obvious and easy to fix. Furthermore, the shell is balanced to the "regular" tension of the bottom head therefore making tuning back up to "how you like it" a much easier and quicker task.

"Tuning Your Snare In The Studio" aka "Did The Drummer Really Ask What Key The Song Was In?"
Want to have your snare sit perfectly into the fabric of a song? Try tuning the top head of your snare to the key of the song. This is a common practice in the "big boy" recording studios. I tend to tune snare drums pretty low in the studio to maximize the "balls" of the snare sound. Surprisingly there is a lot of crack down low if your playing can handle a lower tension. Also, it's easier to accentuate crack via EQ than it is to EQ some whump where there is no whump. Low tension snares tuned to the key of the song are a perfect opportunity to tune the snare's bottom head up to a perfect fourth. Adds a little crack to the whump of a low tensioned drum. If your floor tom is tuned to the key of the song, however, I recommend tuning your next highest tom to the 5th above the tonic. Then you can fit the snare between the 1 and the 5 by tuning it to the 3rd of the key. This helps minimize snare buzz due to interaction with the toms.

" You Got A Hole In Your Head"
Holes in bass drum heads are like colonoscopy. A necessary evil in a live setting. Most soundmen at a club level do not have the luxury of being able to isolate the kick drum sound, and maximize click AND thump without a hole. Since the big dogs usually use 2 microphones for the kick (usually a SM91 inside the drum, and an SM 51/ D112/etc. in the hole), the hole becomes mandatory unless you mount the microphones inside the kick. So where to put the hole? How big should it be? As far as size goes, 5-7 inches across is all you need. Any more, and the tone of the head significantly suffers. More head, more tone. Any smaller, and you can't position the BD mic very easily. As far as where to put the hole, a lot of cats put the hole in the lower left or right hand corners of the drum. This is a useful technique if you want a lot of  richovertones in your kick sound This is the method we used on Rihanna, and that we currently use with Train. Sometimes, however, I need a tighter, punchier kick with controlled, but voluminous bottom-end. I achieve this by cutting the hole DEAD CENTER of the bass drum head. Think about it like dropping a pebble in a pond. The circles of sound go outward from the center of the head. By cutting the hole dead center, you maintain the continuity of the circular soundwaves. Plus alot of the air from the beater strike shoots straight out of the center. This tends to tighten the sound of the kick without sacraficing bottom end. I began using the "center hole" technique with Kenny Aronoff on a Melissa Etheridge tour. The FOH mixer said the difference was night and day in terms of punch, bottom end, and control.     

BTW, two products I recommend for cutting the hole, are the Aquarian Port Holes or the Remo Dynamos hole templates, and "The Hole Cutter". The template is a must. Not only does it give you an easy, almost fool-proof guide for cutting a clean hole (please use an exacto knife or "The Hole Cutter"), but it protects the hole from tearing, AND acts as a gentle mute for the front head. This greatly reduces the amount of muffling needed (so you get a bigger sound), and you can avoid the tone robbing felt strip many people use. "The Hole Cutter" is an outstanding tool for the hole cutting procedure. (Hence the name, LOL!) Strangely enough, it doesn't fit perfectly within the Aquarian/Remo templates, but you can make it work.

Finally, use a protective disc where your beater hits the BD head. I know some people complain about how it affects the tone, but they really do protect the head from breaking due to friction. They can also add a little attack to your kick sound. Remo falam slams are great for rock and funk drumming, but are a little heavy for some cats. Evans makes a thinner less intrusive kick patch that I absolutely love. Drum on brothers and sisters.

More to come. Also please check out the video for the song "Day Is Done" from my band So Called Underground from our new CD "How To Paint A silver Lining". This is a fine example of what can be done with 4 drum mics, and some good drum samples. Hope you enjoy.
