can you increase the clock frequency x4? then design a PCB with a ground plane on both sides. put the clock part far away from the in and out. run dedicated traces for power from the place V+/V- enters the boards back to the clock. put 10nf directly next to the power pins of the clock IC. use shielded cable for all audio signals. that should sort you out.
you are getting a 2 layer PCB made right? you can also use board mounted pots to reduce clock bleed. let me know if you need someone to do the PCB layout.

Thanks dude! I made a two sided one and it's pretty much finished. I need to rearrange a few traces though.
The rotary switch in the bottom center changes a relay to be able to get reverse saw and sine on the lfo with two different parameters/tones/whathaveyou plus lfo off for both sounds so it can just be used with the envelope. Or the envelope can go in parallell with the lfo. Yep.. it's a weird one. The pots are already board mounted but I'll try decoupling the way you described. Thanks again. I have a feeling that some wires might be getting a bit close to the noisy part of the board so I'll make sure to make the traces go to the right place on the next one.

Thanks dudes! I had my doubts but have since found that it works pretty swell with other effects like delay and chorus (ce-3 modded to a 2) .. I've since found the clock noise is practically non-existent now it's on the board. What I mind 'uck
