The Subsonic Analog Octaver is a recreation of the classic OC-2. Starting with the original circuit and components, the Subsonic improves upon the OC-2 with the removal of the active bypass circuitry. The output passive mixer has been replaced with an active mixer, allowing for signals to go well above unity gain. And finally, the Subsonic allows for higher input voltages (up to 18V) for even more headroom for hotter signals. The Subsonic is faithful to the original tone of the OC-2 while adding modern upgrades that make it even more useful.
