I wanted to build a spring reverb that has:
-Low noise
-Balanced inputs and outputs
-A high shelf
-Highpass/Lowpass filters
-Switchable tanks for different reverb times
The attached schematic is what I came up with. Would you mind having a look at it?
I stole all the blocks from other designs.
The filters are from Harrison/Harrison Ford
The high shelf is from Douglas Self's Small Signal Design
The reverb drive and receive are from here: http://sound.whsites.net/articles/reverb.htm
I just stitched them together.
A couple of specific questions:
How do you calculate the worst-case input impedance for the low-pass filter? I need it to figure out the an appropriate value for C35.
Do you have any recommendations for minimizing hum/noise? I lashed a similar circuit up on the breadboard and it was pretty noisy. I figured I would get it all in a box and experiment - but any advice you had would be appreciated.
Thanks,
Ben
