AMPEG SBT Description
- 120W, 4-15 in. 421A Altec speakers (2-15 in. speakers in each cabinet), bass piggyback with two speaker cabinets, solid-state chassis, two channels, silver front control panel, four inputs (two for each channel), seven knobs (Ch 1: v, t, b, mid-range, Ch. 2: v, t, b), ultra hi and ultra lo switches for each channel, Ch. 1 mid-range freq. select, black covering, blue/gray grille, mfg. 1969-1971.
Ampeg borrowed a design from the Acoustic 360 in the SBT by including only the pre-amp in the head unit and adding a separate power amp to drive each speaker cabinet. The speaker cabinets featured input jacks, a level control, and an on/off switch as well as a four-wheel dolly. Because the head alone is unable to drive a normal speaker cabinet, it is virtually worthless without the cabinets it was sold with originally.
