Mindprint enVoice Pre-amp / EQ / Compression stage
A very nice piece of kit, this. Not designed for use with a bass guitar rig - in fact, it's a studio outboard unit principally intended for use on vocals - but it suits my purpose very well.
As you'd expect from gear of this quality, it has a very low noise floor. Features include 3-band EQ, a battery of useful filters, and a cleverly designed valve saturation/compression stage.
