Hey guys,
It is hard to make it available since this was my dream preamp.
But I need to sell my MB-1. I am not using it that much and I need some cash...
All buttons/switches/petentiometers work like a charm. It is pretty noiseless, never been modded and the only detail is that scratch on the top. 115VAC version.
Please PM/email me with offers.
It will be shipping from São Paulo - Brazil with proper insurance.
