I am a tube amp guy, through and through. I am a hobby amp builder in fact, and most of my amps are home built. Trainwreck Express, Blackface Bassman, Brown Princeton Amp, Blackface Princeton Amp, and the one commercial amp I own is a Vox AC10C1. I've started to feel like I should have a backup rig in case my amp craps out at a gig or rehearsal, but don't feel like carrying two amps around. So, I've built a small pedalboard system that can either be used to drive a speaker cabinet, or can go direct to a PA. The photo shows the board with a 30 watt Mooer Baby Bomb amplifier installed, but you can also see my DI (off to the left) which can be swapped in for the Mooer when appropriate. What are you guys doing for backup rigs?
