1/4 jack wiring to circut board
« on: November 13, 2012, 09:03:21 PM »
im trying to figure out how to add a footswitch to my separate spring reverb tank that i built. I can't find anything on how to connect it to my circuit. i have put off making the circuit until i  can figure out the footswitch thing. PLEASE HELP!

You may start by posting the schematic of what you built ;)

+ 1

Also I look forward to seeing it, I've thought about building an external spring reverb for my amp.

Look at most any old Fender tube amp and see how they did it.  They ground off the reverb unit return line.

Ok. so. Please tell me if i am completely wrong. Could i free wire a stereo jack with the receiving end to the IN, the first sending end to the INPUT's 3rd prong, and the second sending end to the OUT?  :-\

Short Reverb pot legs 1 and 2 to mute.
Add a mono jack .
It will pop, but the designer allows for DC through that pot.
Not my fault.
Or you can short reverb terminals S3/S4, about what Fender did in the old days.
Your footswitch cable must be shielded, because it carries signal.
The reverb circuit design is weird.
On one side, it incorporates sophisticated pulse stretchers as peak clipping indicators; on the other uses PNP transistors in an awkward way , seems to be unable to calculate their bias (so adds individual bias trimmers) and allows DC through pots, which is at least scratchy.
Oh well.

PS: and it asks for a driver transformer, when by proper choice of tank impedance it could be avoided.
I think Craig Anderton's Stage Center Reverb is better than this one, and simpler to boot. (and has footswitch reverb control).

If you say theory and practice don't agree you haven't applied enough theory.

That's what I thought, just didn't want to sound cruel. Oh well.
