Hi, just put it together this weekend, used the Opto-Tron for the switch, only bypass works, got a pulsating or throbbing noise much like a heartbeat running the effect, no effect. I'm using a white H11F1 for the Opto-Tron. Same noise running it with or without the 78L05. The BTDR-H3 seems to be the newer version. It's size is different from the BTDR-H2 I have. Changed the H11F1 into a black one and tried another white one, same issue, changed the TL072, same issue, changed the 78L05 to one made by Motorola, same issue! Any ideas? Thank you for help! U4U
..works now, had some issues with the switchcraft jacks! Great device, but not half as good as my Hardwire Supernatural, of course, but very different sounding!
