Updated: June 12th 2014

This is our heavy duty Junior chassis. We've taken what we've learned from the larger Universal chassis and created a 12.25" x 6.875" x 2.75" chassis that is fully compatible with our Universal PCB and Tweed 5E3 PCB, as well as Epiphone Valve Junior-sized cabinets. The chassis contains pilot holes instead of fully drilled holes for maximum flexibility. The chassis can be easily drilled to install boards from Guitaramplifierpcbs.com and Turretboards.com as well. CAD layout by particle.

Our first delivery of 25 chassis has just arrived. We are now taking orders!
