  1. Hey all,

    Thanks so much for keeping this amazing community alive. It's always a good day when there's new layouts on the front page :)

    Would a layout for an Ibanez FP-777 Flying Pan be possible? I think a suitable schematic can be found here:
    https://www.tonehome.de/ibanez/big-box-series/fp-777-flying-pan/

    Alternatively, BYOC once offered the amazingly named Soaring Skillet - the schematic is available in the build documentation:
    https://byocelectronics.com/soaringskilletinstructions.pdf

    Fingers crossed for this one - thanks!!

    1. Hey, I just finished a vero for the panning circuit. Just that side is 30x20, 40 cuts, and 14 jumpers. I need to spend some more time proofreading, but this might be a nice standalone circuit to pair with various modulation pedals.

    3. Happy Landscaper requested a layout of the Ibanez FP777, a phaser and stereo Panner. I have made a Stripboard of the panning circuit.

  4. Hi,
    I built one using this layout.

    It sounds as expected, a Marshall sound. However, the single-coil pickups are a bit noisy, so a buffer pedal seems necessary up front.

    I tried using the NE5532 and OPA2134 on the palce of IC1, and there was almost no noise. But in this case, the sound was less aggressive and slightly smoother.

    Thanks!
