Holy Grail Bass Tone in a Pedal: Origin Effects Unveils the All-Analog BASSRIG Fifteen Amp Sim/DI 
The BASSRIG Fifteen by Origin Effects is an all-analog bass amp simulator meticulously recreating the complete circuit and feel of the vintage Ampeg B-15.

Origin Effects, the acclaimed British pedal manufacturer, has officially launched the BASSRIG Fifteen, an all-analogue bass amp simulator and DI pedal that meticulously recreates the legendary tones of the vintage Ampeg B-15 Portaflex combo. This compact pedal brings the revered “flip-top” amp’s warm, punchy, and studio-grade sound—often called the “holy grail” of recorded bass—to modern stages and studios.

Capturing the Soul of ’60s Bass

The Ampeg B-15 is famously known for defining the sound of ’60s soul music and being a long-time studio favourite due to its rich, clean tones and subtle, musical overdrive. Origin Effects’ BASSRIG Fifteen encapsulates this legacy using their sophisticated Amp Recreation circuitry, previously seen in the RevivalDRIVE and DELUXE55 pedals.

“The BASSRIG Fifteen is not just a simulator; it’s an all-analogue recreation of the entire vintage valve amp circuit,” explains a spokesperson for the UK-based company.

This cutting-edge analogue design includes:

  • A simulated preamp and phase inverter.

  • A push-pull output stage with a reactive load.

  • Rectifier sag for authentic power supply response.

  • An all-analogue 1×15 cabinet simulator.

This comprehensive approach ensures the pedal captures both the sound and the feel of the original B-15 amplifier, making it an essential tool for professional bassists seeking vintage tone without the hassle of vintage maintenance.

Pro Features for Modern Bass Rigs

Designed and built in England with premium components and a rugged brushed stainless-steel enclosure, the BASSRIG Fifteen is built to withstand the rigours of touring.

Key features for the modern bassist include:

  • Versatile DI OUT: Provides a studio-ready, cabinet-simulated signal for direct connection to mixing desks or recording interfaces. Flexible switching also allows for a clean DI, a cab sim for other preamps, or an unfiltered preamp output.

  • AMP OUT EQ Circuit: A comprehensive control set for players connecting to a traditional bass amp. This unique EQ allows users to match the pedal’s tone to any modern full-range bass amp, giving a modern stack the characteristic response of the B-15’s ported 1×15 cab.

  • BLEND Knob: Mixes in a clean signal for parallel processing and tonal flexibility.

The Origin Effects BASSRIG Fifteen is an indispensable tool for bass players in the United Kingdom, Europe, and worldwide looking to infuse their sound with the classic warmth and punch of an Ampeg B-15.
