Updated: May 9th 2015

This is our heavy duty universal chassis. We've made some improvements over the standard 16" x 8" size, and this chassis 1/2" taller than standard to make it easier to work on and accommodate more parts. It's also comes with pre-drilled holes for switches, lamps, pots, and jacks, as well as all cut-outs for the Universal PCB and the Tweed 5E3 PCB. It will also work with most Valve Junior-compatible PCBs (such as the Baby Will PCB from Guitaramplifierpcbs.com, and turret boards from Turretboards.com) with very minor modification. CAD layout by particle.
