PH-2 Superphaser Mods

The two issues I always had with my phaser were 1) it gets mushed out in the mix and 2) it is a one-trick-pony that I really only used for rotating speaker emulations. These mods gave me a whole new device, especially my Pulsar mod.

  • LFO Disable Switch converts the phaser into a cool filter/EQ
  • LFO Pulsar Mod for a very unique Throbbing phaser
  • Output Gain Mod for a beefier output

These mods are of my own design and I have not seen them anywhere else. The schematics are well documented and available all over the internet. BOSS, SUPERPhaser, and PH-2 ARE TRADEMARKS OF THE ROLAND CORPORATION AND ARE USED FOR REFERENCE ONLY. THIS SITE IS NOT AFFILIATED WITH THE ROLAND CORPORATION IN ANY WAY.


Here are the schematics for the PH-2. Click on a picture to enlarge it.
The top schematic is the bare unedited design.
The lower schematic shows the 2 ares of interest for these mods: the LFO circuit and the output mixer/amplifier.
