Pearce BC1 Pre-amps (3 pcs)
Yes the original Billy Sheehan Preamps.
Two units from 1986 the third one from 1987.
The second unit in the picture has the Billy Sheehan modification.

All three amps have worked in my possesion.

The other two are not working.

They switch "on" fine, LED lights up, but no sound..

These amps all need service 

A good technician gets them all going.

The G2X in the pictures has already been sold

Price: €. 600,00 for the set of three (exclusive shipping)
