I'v been working on tube amps for a long time as well, but alot of times the tubes are cold, or removed. Usually in amps I'm more concerned with not completing ground to get shocked or discharging capacitors. In pedals, this is gonna be fun!I didn’t even think of that. Maybe I’m optimistic, or maybe its because I’ve been around tubes for so long, but let’s hope anyone who orders one knows better. Lol.
