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.
