U-Boat V1.5 – Suboctaver

[wpdm_file id=67]

 

Sub-Octave-Effect based on Merlin Blencowe’s circuit.

Most of the Sub-Octave effects today (if we talk analog here) are based on the Boss(TM) OC2 circuit. Merlin has digged up another method to generate an octave effect and designed a nice circuit around it. Learn more here:  http://www.valvewizard.co.uk/uboat.html

 

This circuit has a few changes to the original circuit:

• True bypass instead of the original FET switching
• A Track-pot has been added for finding the sweet spot where the octaver works best for your guitar pickups.
• The envelope follower part has been altered to a more standard circuit.

See a demo of the pedal in use:
