I figured the cali compressor would be great, but I was incredibly impressed with the vintage microtubes. I'm still pretty new to bass and my only experience with bass overdrive is the drive on a Verellen Meatflip (think I've got that name right) which I LOVE, but wasn't sure if I'd be able to achieve a similar effect going direct into the reddi with a pedal. I don't know how close it is to that specific Verellen drive, but it definitely accomplished task and got me what I was wanting. That's a dang good pedal.
