Is there a reverb mix CV input ?
lumin
Does this also work with BEMI/BUSA easels?
Fuzz
What does this do?

Check the link at the top - takes you to the thread with the background and sound files too

Looks interesting, Boops!

Any banana socket can be rewired and used as a reverb mix CV in, for example a "pressure" one, who needs 4 of these ?

I bought one of these and upgraded my 208. It is definitely an improvement. I added a Boops Card 12 Replacement page to my website with photos.

I felt a little like the cobbler's children so I took the opportunity to add a number of mods to my 208 while I had it on the bench. I kept finding and modifying other's 208s but never went back and added them to mine. Now it performs much better.

Which mods did you do Dave?

They are all listed on my page. From memory:
Adjusted the AM level so it is the same as FM and BM (resistor tweak)
Adjusted the CO HF trim (resistor tweak)
Adjusted the MO offset (resistor tweak)
Adjusted the CO offset (added a resistor)
Adjusted the timbre so it is always stable (resistor tweak)
Modified the AM so the control goes 0 to 100% and doesn't over-modulate
Adjusted the CO coarse slider so it doesn't flatten at the top (added a resistor)
Changed the contour of the reverb mix control (added a resistor)
and then I rescaled for 1V/Oct so it would play nicely with my 258s and my 5U system.

Previously I had tweaked the sine with resistor changes for a good shape. Mostly the mods are simply improving performance by fine tuning things.

The AM does over-modulate which in itself could be a feature, but it seems rather odd to me and really makes the output quite hot.

Thanks Boops and thanks Dave! w00t This is fun!

A reverb mix level CV circuit (vactrol based) is ready to test,more in a few days
