BTO Slave Controls

BTO
Slave Controls
(SL260)


Meant to power additional speakers for larger venues this amp would be fed a line level from another amp or mixing board, hence the term slave.
This particular example of the BTO Slave has had a pre-amp section added for use as a bass amplifier. The four silver tipped knobs on the left are custom. A stock Slave would have only the large center "Gain" control.
