I have a OBP1 and when i turn it on it sounds fantastic, i wish it would also make the bass a bit louder. Does somebody happen to know if this is the case with the OBP2 or 3?
I know that the sadowsky preamp can add some volume and is FET designed. The OBP2 and OBP3 are some different design, OBP1 is all FET also, so my fear is that 2 and 3 will sound different but i have not ever tried them yet.
