Trace of a 'Stax Master' designed by Lee Anderton & Sean Michael. The printing on the enclosure suggests that it's painted by Tayda or a company which uses the same printing method.
Op-amps are SMD 4558s. Whole board is SMD actually so I couldn't get capacitor values for everything.
The TS side is pretty boring but the BB side is cool if not a little dark.
White side is first in the chain, and is followed by the Black side.
Overall it's extremely average in all regards.
