Hi everyone. I recently bought a Washburn VGA 30 amp and I'm in love with its overdrive. For lead parts, I feel it needs some reverb (putting a reverb/delay before the amp doesn't sound good, because the overdrive is after). Since the amp doesn't have a reverb unit, I'm considering the addition of an FX loop.
I have someone specializing in electronics who'll help me, but I need to provide him with some guidance. I'd really appreciate any help. The amp schematic can be found here: https://www.dropbox.com/s/sn6herqivuxqdc8/VGA-30.jpg?dl=0
Thanks in advance!
Welcome bardaro, :)
Best place is most likely between output of Volume and R131 (10k)

Thanks a lot, Phil!
I saw there are some FX loop kits available on the market, but they are for tube amps only. I read that for solid-state amps things are easier. Do you know what it's needed to create one?
Thanks!
Well This is about as easy as it gets you need 2 sockets one with a switch.
The return switch opens when you insert a lead. See pic.
You may be able to just lift the input end of that 10k resistor or you may have to cut a trace on the pcb and insert the loop there. Don't forget the ground back to the circuit board

I totally agree with Phil, somewhere between the volume pot and IC102.
It would be best before or after R131, if the picture I found on the net is correct then there are 2 PCB's in that amp.
I would find the correct wire between the pre-amp PCB and the power-amp/ power supply PCB and cut that wire to install the 2 Jacks.
I keep thinking/hoping that Phil plays Bass guitar with a moniker like PHATT, Phatt just makes me think of a deep fat bass riff being played.
I know its made up from parts of his name, but still, what a cool name for a bass player. :)
Oh Tassie, yes it does conjure up a picture I guess. ;D
Mate I have trouble going from a fender to a Gibson as the different scale length just messes my brain something shocking.
And PRS scale length I'm get lost past the 7th fret.
So a Bass scale length is just way out of my ability.
As for drums you have to use hands and feet. ARRH!
My feet are too far away from my brain. ::)
I used to have a Lespaul copy for years but once I started playing Fenders I was able to expand my ability further up the fret board.
Because I tend to finger pick a fair bit
It's darn hard trying to play a 3 note triad past the 12th fret on a Gibson whereas on a fender it's so much easier and I'm able to do much more on the higher frets.
I know many players seem to have no trouble swapping scale lengths but my brain just grabs the wrong fret even if I'm looking at the fret board.
But I know my ability improved rapidly once I started using Fender Scale length.
Phil.
