100 Watt Biacrown Heads

Biacrown Maxwatt S100

This is another very unusual Biacrown variation on the four-input Hiwatt head, and looks very much like a CP-103. Note the MAXWATT GB" logo on the face plate.

Biacrown OL100

This is an unusual Biacrown variation on the two-input Hiwatt head. The two input jacks have been moved to the far left, and a separate OVERDRIVE control has been added on the far left. Also, the control normally labeled BRIGHT VOLUME on a two-input head is just labeled BRIGHT.
