| UPDATE: It is a good idea to buffer the waveform output. Use a 0.1uF ceramic cap after the 100K resistor. The Mod works great and is especially good at high resonance levels, so make sure you include the Resonance Boost Mod also! | UPDATE: It is a good idea to buffer the waveform output.

| According to RobbinWhittle, all you have to do is short out R47 (10K ohm resistor) by a length of insulated wire. Some other x0xers tried it out, and found that mounting a 4.7K ParallelResistor along with R47 works better (giving 3197 ohms resistance). This will also affect cutoff range to a degree. | According to RobbinWhittle, all you have to do is short out R47 (10K ohm resistor) by a length of insulated wire.

To explain r46... it seems to add more squelch on the accent, it's kinda subtle, but I could notice it most when the cutoff was way down it seemed to let through more resonant "scream" (sounds like "wow")... | + | [[http://www.ladyada.net/forums/profile.php?mode=viewprofile&u=103|Subatomic]] tried mome's mod, and found that it can be a bit whistly, but good, I went with a pot though so I could tweak.
