foot switch question
« on: February 17, 2013, 10:43:20 am »
The schem is on page #7.
Is the Reverb normally On with this amp.?
I am not sure how it works. When the switch is closed, it looks like the node between R31 and R65 is connected to ground. Does that turn the Reverb Off.?
Thank You

What do you mean? The reverb will be on when the footswitch is open OR if the footswitch is unplugged.

Yes, that's how it works.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Thanks Sluckey -
Yeah that is what I meant by "normally". If there is no foot switch plugged in.
Thanks Again
