there are some trim pots inside of my SK20 and I would like to know what they do, hopeing to slow down the vibrato a bit and ease off the chorus effect a little. but i dont wanna break it in the process.

if any one has any info on this board let me know, thanks!

use a search engine.

I did, the first few pages where filled with pay sites. (:I) But thanks for the link any way!

that link was exactly what I asked for when I requested a manual. however after looking it over I find that it did not have a diagram of the circuit boards. any one have any info on what trim pots do what in that board?

thanks in advance!

Here's the SK15 service manual. Surely they share some of the same electronics.
