Re: [AH] driver-less spring reverb?

Nice circuit for simple gain structure but I think could omit the output 
opamp / pot and the wet/dry pot to make it even more simple.

Or... keep it as is but add a feedback pot.

This is something that I use a lot on my Doepfer A199. Feedback 
distortion on a spring reverb is cool.
