EBS Octabass mod by mistake
I just bought an OctaBass and tried it out when I got home. It wasn't octaving right. Instead of a lower octave, it was just making the current note fatter and synthy. Not quite right, but really cool. Then I realized that I forgot to plug in the pedal with my OneSpot and was using the battery that it came with. Plugged it in and everything is working fine. Octaves as normal. Unplugged it and it's back to the phat synth sound.
I checked the voltage on the battery using my batt-o-meter and it read 7.98 and 8.04 V on two different readings. So if you have an old battery or the Sag function on a PedalPower or similar, definitely give it a try.
