Looking for Gibson GA 20 Editable with express pcb

[scottahicks]

I am looking for a Gibson GA 20 schematic in a format that can be edited on express PCB. I am considering adding a reverb circut to the build that I am working on.

Any help would be appreciated

Sorry but don't think you will find that.
Your amp is Point to Point wired, no PCB whatsoever
The circuit should be modified; tubes, sockets, driver transformer, etc. should be added , your power supply must be able to power the extra electronics, etc.
That said, you best bet would be to build a *Pedal* reverb , either into an actual (very large) pedal or in a chassis/cabinet mounted by or over your amplifier.
Post whatever codes are written on your reverb tank.
Maybe the "Stage Center Reverb" suits you, maybe something similar.
Google it to see what are you getting into.
They offer a PCB design, ready to transfer.
Worst case, you can hone your Express PCB skills by designing your own PCB.
Good luck.

Ok, I thought about using express PCB just because it is a free layout cad... if there is any other free schematic layout programs that would help me digitaly recreate the schematic and modify it that would be great.

Well, you can draw the schematic with Express PCB and edit it at will ... or you can use old paper, pencil and eraser.
That's what I start with, before getting into any software.
