Spin Semiconductor

No. None. I simply took the in/out buffer circuit from the Ibanez AD-80.

I modified the input buffer to give a gain of +10 instead of +1 to drive the FV-1 input harder, and modified the output buffer to compensate to bring the dry level back to unity gain. The wet signal is now dead silent....I mean in terms of noise. The FV-1 is working perfectly and is extremely quiet....

I just put it in the FX loop of an amp, and it's dead quiet. Does the FV-1 like to see a hot input signal?

http://www.byocelectronics.com/lilreverbpic.jpg I think the chip is fine still. The outputs weren't initially tied together or to ground. I tried that later and it caused clipping or nothing at all, so I undid that and it went back to the way it was before. The PCB is laid out almost like the schem...

Originally, I left both the right in and out open. Tying the outputs together caused some clipping, but aside from that, I didn't notice any difference as to whether or not the unused I/O was grounded, NC, or tied to the other.

http://www.byocelectronics.com/lilverbschematic.jpg I'm working on designing a very simple guitar reverb using the FV-1. So far it sounds good, but it's a bit noisy. Please take a look at my schematic and let me know if I'm doing something wrong or if there's something I can improve. Or is the FV-1...
