Rebote Delay - 1590A

For those of you who didn't want 1590A week to end last month, here's another mini layout for you. It's an early iteration of the Rebote Delay that features a simple JFET stage at the input, followed by the PT2399 delay stage. Simple, yet effective. Note: mind the 3 electrolytic caps on their sides in the middle of the board. Here's the schematic for reference.

    1. That wasn't introduces till the Rebote 2. Different circuit design.

  3. couldn't the Mix knob be added simply putting a volume knob at the delay chip output?

    1. That would just be a volume knob which isn't really necessary with this. It a PT2399 delay like later Rebote iterations or the Deep Blue Delay, the mix knob essentially blends in clean tone with their input and output buffers. This one uses a jfet gain stage to keep the volume at unity. A mix control could be added to this circuit, but probably not without adding some sort of buffer. You could try adding a blend circuit, but that would be difficult with this PCB, not to mention difficult to cram into a 1590a.

  4. ever think about making the circuit to fit 1590B?
    I'm tired of my DBD clone, really.. :D

    1. Coz I think it would be interesting to have two delay pedals in a box, just like what I did to my Em-drive and Paramount.

    2. and yes, this one sounds better than DBD to my ear

    3. If it fits in a 1590A it'll fit in a 1590B no problem.

  5. It's working but volume is waaaay too low. Any idea?

  6. Updated: Changed the tranny to a 5458 and it works great! Mark it as verified sir, thanks for your amazing job.

  7. Can I use this blend without buffer? Thank you

    1. You can use that blender, though it will be somewhat difficult with this layout.
