I did the cutoff mod yesterday and am VERY pleased with the result!! Much better range, especially in the low end!!! Thanks millions CoolColJ !!

This mod is easy and highly recommended!

I tried them but it's not enough.
So what is the next opinion to expand the top-end of the filter.

Can i replace the TM3 with a lower value or is there another way to expand the Filter in the top?

The hint is to reduce the R97 (10KΩ)a little bit to get this effect!

this is the "resonance boost" mod documented in the x0xd0x! we're trying to figure out what value @r97 sounds good but doesn't go into "lazer zap" territory.

what value did you decide to use? can you post audio samples?
