Origin Effects Unveils the BASSRIG Fifteen

A Faithful All-Analogue Homage to the Legendary Ampeg® B-15

November 2025 — Origin Effects has expanded its acclaimed BASSRIG series with the launch of the BASSRIG Fifteen, an all-analogue preamp & DI designed to deliver the definitive studio bass tone of the iconic Ampeg® B-15 Portaflex®. With its unmistakable warmth and vintage character, the B-15 has been the foundation of countless classic soul, R&B, and Motown recordings. Now, Origin Effects brings that unmistakable sound to modern players in a compact, studio-ready pedal.

A Legacy of Studio-Ready Tone: The BASSRIG Series

When Origin Effects introduced the BASSRIG lineup, the company’s mission was clear: recreate the world’s most influential bass amps in studio-grade, all-analogue form. The first releases—the BASSRIG ’64 Black Panel and the BASSRIG Super Vintage—set a new benchmark in the bass community. The ’64 Black Panel captured the clean punch, clarity, and mid-scooped American tones of classic Fender® amps, while the Super Vintage delivered the woolly growl and authoritative low-mid presence of the Ampeg® SVT—another titan of bass history.

Praised for their authenticity, low noise floor, cabinet simulation, and mix-ready DI output, the original BASSRIG pedals quickly became essential tools for bassists on stage and in the studio.

Now, Origin Effects completes the trio with a preamp inspired not by arena bass rigs, but by the small, soulful combo that helped define recorded bass tone as we know it.

Introducing the BASSRIG Fifteen

With the BASSRIG Fifteen, Origin Effects turns its attention to the Ampeg® B-15, the world’s first purpose-built bass combo amp and perhaps the most recorded bass amplifier of all time. Loved for its warm cleans, smooth breakup, and uniquely musical compression, the B-15 became the secret weapon of countless session players throughout the 1960s and beyond. Its low-powered tube architecture and distinctive folded-horn cabinet made it a natural studio favorite—and a timeless piece of gear that still commands reverence today.

All-Analogue B-15 Feel

The BASSRIG Fifteen recreates the feel, tone, and responsiveness of the Portaflex with all-analogue circuitry—no impulse responses, no digital processing, just pure electrical artistry. Players can expect:

  • Authentic B-15 clean warmth paired with gentle, harmonic tube-style breakup
  • Vintage-voiced EQ that responds like the original amplifier
  • Inspiring touch sensitivity that rewards expressive playing

Modern Tools for Modern Players

While it captures vintage tone, the BASSRIG Fifteen is engineered for contemporary workflows:

  • BLEND control: Mix clean signal for enhanced articulation and low-end clarity, ideal for modern pop, rock, and gospel playing
  • All-analogue cab sim on the DI OUT: Delivers studio-quality direct tone without requiring external IR loaders or extra hardware
  • AMP OUT EQ: A powerful post-preamp equalizer that tailors your output to suit any backline rig, ensuring consistent tone on any stage
  • Instant mix-ready sound: Plug direct into your audio interface, stage box, or PA system and get polished, record-quality results

A Modern Classic in the Making

The BASSRIG Fifteen bridges the golden age of recorded bass tone with the demands of modern players. Whether you’re chasing the warm thump of classic soul, vintage rock roundness, or simply a beautifully musical bass foundation for any genre, the BASSRIG Fifteen brings the B-15 magic into a rugged, pedalboard-friendly enclosure.

With the release of the BASSRIG Fifteen, Origin Effects now offers a complete analogue toolkit for bassists seeking the world’s most iconic amplifier voices—each captured with uncompromising detail, studio-grade polish, and road-ready reliability.
