  • Variable Chorus question

    I'm going to install a pot in a buddy's C3 for variable chorus...Does anyone know if I need to remove that 22k resistor that's installed (I think?) In the V/C selector switch?
    Over the years: Hammond M3, BC, M102, B3, four X77s and three PR-40s, a Thomas Electra and a Celebrity, three Fender Rhodes, Roland HS-10, HP-2000, HP-600, RD-600, JV-880, a thing made by Korg (?), two Leslie 910s, 122, 257, 258, 247, two 142s, and three custom-built Leslies. Wow, way too much money spent!

    According to the hammond wiki - no.

      Depends on whether you want to be able to go shallower than stock with your variable potentiometer. If the 22k is left in place, the stock value becomes the "minimum depth" (which is probably just fine)
      Current organs: AV, M-3, A-100
      Current Leslies: 22H, 122, 770

        After some trial with a pot, we decided to settle on a fixed amount and I ended up adding another 22k resistor on the line box, paralleling it with the 22k in the V/C selector, bringing the total resistance down to just under 12k, which matches what's in an A100. Both modes now sound great.
