Random - it’s a colourbox - not colorbox - spelt the British way - no idea why.
Ive had one of these at the end of my pedalboard for a while, in fact the only reason I have a pedalboard is I picked up one of these first.
it sounds beautiful
I mean ideally I would like a guitar tech where I just pass them my bass and they pass me back one in tune, but it might be a bit odd when playing at church on a Sunday morning, so anything will probably work right?
I’ve used Elecrow you can use the prototyping service and 10pcb costs about £5 posted - takes ages and you have to get the kicad file right. (Tip standard hole size is not big enough for diy pedals!)
judging by the plugs in the background I don't think @RonC is in the UK, which is fine but don't be surprised if they drive (or wah) on the other side of the board
If you open it up and have a look and see if you can see anything obvious you might have a "new power jack" issue which can go to any music shop, or person who can fix electrics rather than a more specific pedal fixer ... which will be cheaper
try and diagnose it yourself first... can you make it repeat the fault, does wiggling power or cables make it cut out?
If it's just the power jack it could be a 10 min fix you could do yourself
took a while to bug fix this... but a Mutron iii (Aion's Lumitron) with a couple of mods... a decay knob and the "Moog filter" mod that does something and makes it sound different
