Ok, so I've got an Aguilar OBP-3 and I would really like to add it to my passive fretless bass, but I don't want to have to route a cavity for the two 9 volt batteries. So, I was curious if anyone has tried to create a pedal out of an Aguilar preamp (OBP-1, 2, or 3) and how they did it and how it worked out. I only found one result on Google, but I was a little confused by the guy's use of an FX loop within the pedal, not that I couldn't figure it out, but I'd like to see what else is out there first. If any of you have tried, or know for sure how it would turn out, please lend me a hand, I would really appreciate it!!!
