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.

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.

So you built the power amp ? How many Watts ? What did you use for a power supply ?

Not sure I would trust using it revered polarity for any length of time.  Honestly I'm surprised it still works!

Power amp is just a Kemo m034n module with in/out Jack's and volume pot. The module is supposed to give 40w into 4 ohms and 16V supply. I am using 12v laptop supply or car battery and its plenty..

Yes I know. That pedal was so cheap I don't mind if it goes. Might put reverse protection on the whole rig though. The pedal PS and all the pedals are centre egative and the amp is centre positive so theres a lot of opportunities to mess it up.
