So had my first practical experience with it this week. Basically, jam night got moved, and then delayed and them moved again to my place (life). Normally we monitor through a mixer/computer interface and I sold my amp to buy pedals. So not having any other way to play and monitor I plugged into a 90's era Fender Squire 15W guitar amp. Honestly, this was a terrible idea and I had zero expectations. However, even though it had no right to work, bass sounded like bass. It didn't kick you in the chest, but it was surprising how much twiddling the filter knobs got it to something that sounded like not-a-terrible-bass amp which is better than I could have hoped for. Even the low-B was audible (don't misinterpret this, there was no fundamental coming out the poor 8" driver). Disengage the OCSD and it got really flabby/distorted (I was accompanying an acoustic guitar so didn't need to push lots of air). Engaging the pedal really tightened up the sound to something that was miles better than I had any right to demand from the little amp. Pushing it too far to the size or closed speaker settings started distorting the driver, or when trying to up the SPL output. Still, a serviceable guitar practice amp became a serviceable bass practice amp. Loud enough to support an acoustic. Not my intended application but I can see myself making use of this. Also my first glimmer of how well this should work over a decent, full range PA.
