Tayda delivery day!
It was a new project and a 3pdt breakout board
Early this year I tired PCBA for the first time and made these lovely prunes and custard clones in Gorva M45 (1590A) with top jacks. I made 6, one for me, one for the friend who suggested trying it and sold 4 of them locally.
Then a guy from Canada got in touch on a uk bass forum, begged to buy my own one and send it to his mum who was on holiday in the uk... I did and then sold him my personal one.
Oh and Lumberg stop making the DC jacks I was using...
Fast forward a few months and I source good parts and stuff to complete another four of these builds...
It's 1590a size so it's more fiddly than normal - Put it together - and works first time and sounds great.
So box it up, tighten everything up and stick it where it used to be... in the loop of my HX stomp...
And suddenly it all goes crazy - massive clippin, noise, feedback squeals everything turning red, the neighbours organising a lynching and the end of the world... WTF is going on...
So bug fix
and bug fix
check all the joints
cut off all my wiring to check its not the breakout board
reflow every joint...
crazy noise. even when off now... what's happening - am I just plugging 9v DC into the jack return or something?
stick it elsewhere in my chain, without the switch by now and - Ahhh it works and sounds great....
plug it in the loop and ARRRHGGGHHH!
What have I done wrong?
Turns out, if you have a patch with both Left and right loop send/return on a HX stomp - and use a TRS -> dual TS splitter cable and loop into loop left.... and just leave loop right unplugged...
All sorts of bad shit happens - nothing to do with my bloody pedal.
Plug in the loop, I guess so there's ground connection, or delete the unused effects loop block and you're fine.Thats two hours of my life I'm never getting back.
but hey you know, I've switched to lead free solder, so my joy of soldering is gone too, so all ok, everyone happy (not), and I've a bigger mess to fix tomorrow than I started with this evening!
