I recently made an Easy Vibe following the original Hollis schematic & 2 TL064 quad OA's...I'm assuming that the 'updated' versions using 4 dual OA's were set up that way because of the annoying LFO tick bleed thru...it seems like it is ticking because 1 of the filter sections is in the same OA as the LFO (should've thought about that first!) Anyway, I love the pedal; the chorus is a little shallow on mine, but I'm into the vibe thing anyway! Really psychedelic :)
SO, I'm just looking for a validation of my logic on stopping the LFO tick...I plan to remove my power supply stuff from the board I've got in there, and re-do it on a separate perf. I will also build the 3 OA LFO section on here, and decouple it as best I can. Tie the V+, Vref & ground back to the main board (decoupled), and strap the new board in the space freed by moving the PS stuff. Does this seem like a reasonable solution to someone who knows the circuit? Since I'll only be using 1 OA on the chip already in there, any ideas on how to leave the 3 others (floating vs. something else)?
