I've had one for many years. It's connected to a Carvin FET1000 amp running a 1x18 bottom and 4x10 top. It's loud and been pretty much trouble free. There is a very simple mod in this thread that I did that gives it a whole new dimension in your sound. I always had an issue with not enough mid range but after the mod, I have more flexibility to getting the sound I'm looking for. I also have an Alembic Superfilter in the rack with it. I rarely use the whole system because it's almost too much for the venues I play at.Has anyone/does anyone know anything about this preamp? It's aone space pre, solid state. Not anything like the redface Carvins. Anyone...? Thanks,GOD bless you!
