Yeah oc2 is still on my board as well, it's it's own thing.
The overload switch when the tone is lower is great with a filter or just to get the gnarly synth tone, I like the tone higher up without the overload switch, seems to sound more like the criminally underrated Aguilar octamizer with the octave tone up, but with the functionality advantages of the sub switch with the independent volume.
So that coupled with the oc2 doing the solo -1 sound does everything for me.
I had a FTelettronica Tetractave in its place before but it's more of an oc2/mutron only with the sub solo - amazing pedal tho, especially for the money.
