Origin Effects BassRig Fifteen
Origin Effects are no strangers to recreating classic amps in a pedal format, and they have now taken on this Ampeg classic low-powered bass combo. This 100% all-analogue take on the B-15 Portaflex is going to be perfect for many bassists who seek classic bass amp tones, and it will do much more than recreate classic 1960s soul recordings.
The BassRig Fifteen is designed to connect directly to a recording input or a direct-to-PA preamp, featuring an XLR DI output that incorporates an all-analog cabinet simulation. It could be the perfect partner for your bass rig, and the compact pedal’s format means you can easily fit one in your gig bag, making it a go-anywhere mini bass rig.
Valve Amp-Style Signal Path
Origin Effects has gone to great lengths to recreate the original Ampeg valve amp circuit using a solid-state analog circuit. They have simulated both the push-pull power amp with a reactive load and paired the circuit with the analog 1×15 cabinet simulator. The three-way DI Cab switch offers Off, FX, and On options.
This should provide modern bassists with a classic ’60s tone, complete with all the modern features we are accustomed to, including a high-quality buffered bypass.
The amp section includes controls for Output, Blend (for adding in a clean signal), Drive, and Amp Out EQ. These EQ controls consist of two mini switches for Lo and Hi Cut. There is also a ground lift switch on the front panel.
