Here’s what’s on the bench today. A JMP 2203 5GS Sniper+ with clean channel. 5th stage and clean are both foot switchable. Still in process, but turning out nice and tidy.

This customer wanted additional gain cut options made foot switchable, so a second jack and a couple more relays were added.

Needless to say, this one is a lot of work, but it’ll be a killer piece when it’s ready to go. I made judicious use of the Gound Zero PCB boards to make it all happen. Takes quite a bit of pre-planning to make sure things go smoothly.

Up to about 45 holes drilled so far. For the inevitable Marshall guy that will be offended by this…
