In the FX loop is the obvious place.

does your Belton have jacks for in/out or a glob of wires?  maybe post the datasheet for the brick  :dontknow:

looks like you can just solder up 2 1/4 mono plugs, one for in, one for out, wire up your power and plug them into the FX loop on your amp FXout--->belton in  Belton out--->FXin and give it a test run.  I would use shielded wire, or cut a guitar cable in half and solder it up.

Connecting the Belton module between FX send and return should work. The problem as I see it (though this is a matter of taste) is the mixer circuit. The dry signal will be reduced as the Reverb (or FX) level is turned up. With the Reverb/FX knob at max, you have zero dry signal.

I would want the dry signal to remain at a constant level, regardless of the Reverb/FX level. The reverb knob should blend in reverb signal, but not change the dry signal level.

I noticed you are right

I connected "by fly" reverb

Pin 7 +5v pin 5 -ground (from external trasformer)
Pin 4 signal in ( send input from fxloop)
Pin 3 ground from fx in e fx out 6.3mm jack
Pin 1 signal out (return input from fxloop)

No reverb

When i turned up loop level, no sound

It seems reverb is not correctly connected however 🙄


--edit--

1Jack was fault...

Reverb works... But after noon setting (12oclock looop pot) effect is too much... Maybe i ve to use some resistance..

Someone have schematic to use?

Don't know if it would help but this is how it's wired into a pedal.
