hi, I too wasn't really digging my double flush. I replaced r17 with 2.2k and then messed with C8 (.22uf) and tried a few different sizes till I went with a .1uf .The pulse is a lot better now. I believe the tone is also much fuller and nicer now. Still not as awesome as my Boss TR2 that I modded.
But sounds way nicer to my ears at least.
