Boss SP-1 Spectrum

 A fairly rare old Boss eq pedal which is rarely cloned due to the dual 10kA/10kC Balance control. However, it is quite easy to make your own if you have a dual 10kA pot and a single 10kA pot on hand. Custom pot tuturial and schematic is avaiable HERE

  2. Verified. Cool effect, although not worth the price these are selling for. It's very useful after fuzz for tone shaping.
    I'm counting 24 cuts.

  3. Also I made my own 10ka/10kc dual pot using the link above. I only had the parts for linear taper, and the sweep works great

  4. Just wondering but as C is a reverse log taper pot and A is log taper could we even just wire the 2nd part of the dual gang in reverse? So instead of 456 solder 654. Im happy to try and make the A/C pot but just thought it may be easier to do thile reverse wiring
