The AMP OUT EQ is our proprietary filter, applied to the ¼” output of the BASSRIG. Its function is to ensure compatibility with any bass amp, meaning you never have to compromise your clean tone in search of the perfect overdriven tone. There are many kinds of bass amp, from small combos to vintage stacks to modern, hi-fi setups – and the dreaded house backline! The HORN CUT switch applies a choice of steep low-pass filters to guarantee a smooth overdrive tone when using tweeter-equipped cabs. The LF control can reduce boominess in large cabs or fatten up small combos, while the HF control fine-tunes the upper mid and treble response, compensating for your clean tone’s EQ settings and accommodating different speaker types.
