This Yamaha B100, 4-digit serial-numbered bass head, was made in Japan during the 1970s and is sought after for its warm, tube-like solid-state tone, bulletproof build quality, and distinct vintage features.

Good shape for 48 years

• Warm, Tube-Like Tone: Despite being solid-state amplifiers, players on TalkBass agree that the B100 series delivers a remarkably warm, organic sound with plenty of clean headroom.

• Onboard Fuzz/Distortion: This model features a built-in distortion or fuzz-tone knob that produces a retro '70s grit highly favored by alternative, doom metal, and stoner rock bassists.

• Exceptional Durability: Built in Japan by Nippon Gakki, these amps are renowned for their rugged construction; many units still run reliably today without ever needing a major service.

• Rarity: Because they were produced in limited numbers for specific markets and aren't overly common on the modern used market, they have developed a cult following among vintage gear enthusiasts.

Currently paired with a vintage Tom Mitchell Mini Bass Cab with a 15: EV speaker. For sale on Reverb for $270
