I had posted a thread about the what effects to use for a sound like "Balek" by Marc Moulin and another TB'r directed to me one of your synth bass vids and the tremolo addition to the chain where you get a very similar sound. He nailed it, thanks Jumblemind. I wanted to ask about your settings on the OC-2 and if you use any other octavers. I have been planning to get soon a Mooer Octave pedal in the micr form factor and I also want to get a POG2 (I've been after a Stevie Wonder-esque clavinet kind of sound for a long time).
Try playing with just the octave 1 (left vol)and turn off the bass itself(middle vol) And the 2nd oct(right vol) off To me this is an amazing bass synth tone! Enjoy!
