Rebote 'oscillation' mod

So I added the instant feedback/oscillation switch to my Rebote 2. I used this layout here with the pot and momentary switch:



Now it does what it is supposed to do alright but a few things I would like to change.
- The oscillation switch only causes oscillation if the repeat pot is set almost to max. Can I make it so that I get instant feedback/osc at any repeat setting?
- If you're not careful the oscillation spins out of control VERY fast and increased volume rapidly. Is there a way to limit this and keep the oscillation at the same volume the delay or guitar signal is at?

Thanks!

it has been used a set of antiparalell silicon diodes (TS style, "clipping diodes") in the feedback loop of the delay, so when it overdrives and blooms, it gets cut at acceptable levels

Hey thanks. Would I want the antiparallel diodes placed somewhere near the output buffer stage (the TL072 towards the output)???
