Ross Phaser

 Yes, Modulation Monday is back with the Ross Phaser. It's not for the feint of heart, but doesn't require any JFETs, matched or otherwise. Instead it uses OTAs with 3, LM13700N (one for the LFO, two for the audio path). Should fit nicely in a 125B with top mounted jacks. Schematic for reference.

  1. It works! you can mark it verified. It does have a vibe and feel like a vintage pedal, and some great phasing sounds.
