Lower the value of the 10K resistor after the speed pot.

I've posted so many mods for this, I figured someone else would respond. This is NOT a snub, just a a loud request from a weary typing hand. Check through the archives and you should find some postings of mine with tons of suggestions for mods to the P100.

AS for speed, it is going to be one of two possible caps: the 15uf cap to ground, or the .01uf cap in the feedback loop of the op-amp. The LFO in the P100 is pretty foreign to me, but mu money is on the .01uf in the feedback loop since that looks like an integrator, and it is the cap in the integrator in 2-op-amp LFOs that you can use for range-shifting. Tack on another .01uf in parallel on the copper/trace side and see what happens.
