The Roland SB-100 Studio Bass delivers full-bodied, vintage bass tone from a single 15" speaker and 100-watt power output. A rare piece of bass-amp history built in Japan in the late 1970s. Known for clean, punchy low-end with detailed mids and a flexible EQ section, it remains prized by collectors and players seeking an old-school bass voice. Heavy, robust and stage/room-ready, it’s a unique combo amp with the depth and clarity to cut through bands or hold its own in rehearsal or recording spaces.
100 W RMS solid-state bass combo amplifier into an 8 Ω load, giving enough headroom for live band volume or rehearsal use.
Single 1 × 15″ R&P (Roland/Pioneer) bass speaker for deep lows and smooth full-range bass response.
Dual-channel operation with High and Low inputs (for active/passive basses or different pickup outputs).
Extensive EQ control: 6-band graphic equaliser offering frequency bands at 75 Hz, 150 Hz, 300 Hz, 600 Hz, 1.2 kHz, 2.4 kHz plus a Level control. Ideal for sculpting tone precisely for different genres or instruments.
Additional master Volume, Treble, Middle, and Bass controls for broad tone shaping when EQ is bypassed.
Rear-panel outputs/inputs include Line Out, Ext. Speaker Out, Footswitch jack (for EQ bypass or external control), and Effects loop (on some units). Useful for linking to PA, external cabs or pedalboards.
Rugged 1970s Japanese construction with black tolex and robust grille cloth. A vintage amp built for real-world use.
Versatile: handles passive or active basses, also usable with synths, keyboards or guitars thanks to broad EQ and clean headroom.
Second-hand, in good condition with minor cosmetic wear as shown.
