BTW I reversed the polarity on the GDI21 and I got smoke but it still works. The only effect is that the LED now stays on whereas it should only be on when an input is plugged in.

Amplifier Discussion / Pedalboard amp
« on: July 08, 2020, 06:07:27 AM »
Just finishing my pedalboard/ box which includes a power amp plus all my pedals. 2 switchable inputs, 12v power via dc jack, and one output jack to cab. Signal path is
Mooer ABY pedal
Boss DS-1, Danelectro Fab overdrive, Behringer Tremolo, Behringer Delay, Mooer Shimverb, Behringer GDI2, Power Amp. Yes, I am a fan of cheap pedals.
Needs a bit of cable management maybe. Not shown is the lift-off lid to be attached with case clips. Demo to follow.

Probably expensive but should get cheaper over time

I have not yet tried to make PCBs but this looks interesting

Thanks for the tip. I now have some lead solder and it is indeed easier to use.

I decided to use wire links instead of repairing the broken traces and have good connections now. I am left with 2 issues, which I can live with but would be nice to fix if possible. One is that there's still quite a lot of hiss.  Also the overdrive still goes crazy from about half way up, after which I get a very loud low frequency buzz.  While half way is more than enough overdrive for me most of the time,  theres obviously still something wrong.
The pot is new, works smoothly as measures correctly (250K linear). All pots have been cleaned with contact cleaner. Could this point to the opamp or the clipping diodes?

You're right about cleaning up my soldering. Yes, its lead-free solder. And I will continue checking the ground connections.

No crackles when I wiggle any of the pots or jacks.
Joe, your mention of ground connections focused me. I think I soldered the overdrive pot, middle leg incorrectly to ground. See before and after photos below. What do you think?

Correction:.
1.At low levels, with overdrive at zero, a. Pretty good clean signal with a lot of hiss via internal speaker.
b. Signal disconnects intermittently when using headphones

I'm having another go at this as I have a bit of time on my hands. I didn't do anything with the opamp but replaced the gain and overdrive pots and repaired some broken pcb traces. I'm left with the following issues.
1. At low levels, with overdrive at zero, a. Pretty good clean signal with a lot of hiss via internal speaker.
b. Signal disconnects intermittently.

3. At higher levels, signal sort of drops out as the note fades l. Sound clip below

Any ideas? I can show bits of my schematic if I can get it finished

I have my Zoom working now as an interface to the PC. I am using Jamkazam for  online jam sessions. Works fine for electric and electro-acoustic but can't get a good  sound with a dynamic mic. Any suggestions on that?

Thanks all. The Zoom has a built in USB interface. I've got it working now using Audacity. And with the Zoom software I've been able to edit the patches to what I want.

Will just try it anyway. If it works and theres no smoke or sparks then its OK.
