A friend of mine sent me this very handy FracRack information. I’m not sure who wrote this up originally, but whoever it was, thanks! Measurements Frac rack modules are 5.25″ high, with widths in multiples of 1.5″. Per instructions on the Blacet website, mounting holes are 1/8″ wide, 0.75″ inches from the left and right […]

Here’s a list of all the voice mods I made to my CR-8000, complete with PCB locations, replacement component values, and a few notes to boot.

Below is my modification of the original CR-8000 bass drum circuit (in blue). Those familiar with the TR-606 mods will notice the similarity to Geoff Waterson’s TR-606 BD Decay Mod. You can experiment with the component values (especially the .047uF cap and 33k resistor) to get different results. I selected a 33k resistor because it […]
