Smallstone mods

[roknjohn]

Does anyone know how to adjust the feedback or resonance of the smallstone? Would like to bring it down at times and up a little farther at others. I have tried the 50k pot to replace the 27k and 30k mix resistors, and although I like this, especially when then color switch is in the vibrato position, I would really to adjust the feedback or resonance. I used the schematic from Tonepads site, the one using 5 3080's. As always any help is appreciated.

Read the post by Mark Hammer a bit down the page. He gives the information you need.  :wink:

Thanks bassmeister.

Must have missed that when I searched past posts. In the meantime I had found the Ross Phaser schematic that uses OTAs and has the REGEN control. I think I can come up with some tweaks between the schematic and the link you have provided.

You just have to convert the url to the new format. The topic number is the same.
