Complete internal side-mounted single trigger assemblies for DIY acoustic-converted, electronic drums
“Exceptional Internal Side Triggering”
  • SideArm mounts directly to existing lug hardware - Vertically Adjustable - No Drilling - working with standard acoustic drums (wooden, metal and acrylic shells)
    • on rare occasions, additional lug screw length is needed for mounting, L-bracket orientation adjustments needed for shallow shells or non-ordinary lug location, or L-bracket needs modification for drums with inner bearing edge shell reinforcement
  • The Piezo/Cone riser is vertically adjustable to fine-tune contact/pressure with drum head and isolated from shell vibrations through a rubber dampener on the L-bracket
  • 35mm Piezo's utilized on all drum diameters
  • Default lead wire length is 14” from Piezo/Cone & includes quick-connects for jack post connections – additional harness wire length is available by custom upgrade
  • Single/Mono zone is standard - add L-Bracket Rim Trigger Add-on for dual/stereo zone triggering - Piezo triggers are velocity sensitive
  • Complete with ultra-durable "Conical-Styled" Foam Cone
  • Works with acoustic or mesh heads (1, 2 & 3-ply).  2 & 3-ply mesh heads provide for optimal trigger performance and best mesh head play-ability experience
  • Installation guide provided via email at time of shipment

The dude
Big fan of these rigs. Currently use Roland td-20 with pd125 snare and kd-10 pedal. Acoustic converted toms with mesh heads and no one knows I'm playing electronics. Td-20 has presets for rim triggers and they work like a charm with my sidearm...I didn't need to adjust the settings at all. I have been testing them thoroughly and they have never missed a hit and don't have any crosstalk. I am very impressed and highly recommend them. Mitch is extremely helpful....and an awesome dude!

Work great on toms!
I used SideArms for my 10/12/13" toms and the response is spot on! Simple install too. I went with the OctaCones because I like their design.

Very happy with these!
Installation was super easy, and these things are solid! I'm using a Roland TD-30 and these perform much better than the external Roland triggers I had been using. I upgraded my order to the larger piezos & the sensitivity picks up the lightest hits with no false triggering...even on the 16" floor tom. Combine these with the 3-ply mesh head, and you're all set.

The SideArm makes it SO MUCH EASIER!
I recently converted an acoustic snare to electronic by using a wooden crossbar attached with L-brackets. It was not too hard to put together, but then Mitch told me about the new SideArms. I had to put together 4 toms, so I gave the SideArms a shot. This saved me a lot of time and hassle. I love the foam pyramid. The 2-way height adjustment is a great and versatile feature (by moving the bracket OR adjusting the screw/wing nuts), and the large L-bracket can be flipped over if needed to fit properly in your shell. You connect the wiring to the jack with these quick connects, which eliminate soldering (there's a time saver right there!). The foam pyramid/piezo assembly attaches in place with self-adhesive foam, just peel and stick. And to top it off: These things are very inexpensive! So save yourself some money and a lot of aggravation and BUY Sidearms for your project. If you have any questions, Mitch is excellent to answer and make recommendations.

Pearl Export hybrid kit
I've tried several different external drum triggers and these are by far the best I've found. Installation is easy and clean.
