There’s also a deep switch, which slightly boosts low frequencies and lowers the cutoff of a high-pass filter (more on that below). The 4-band EQ is standard fare, with shelving bass and treble filters accompanying two bands of peaking midrange.įinally, master operates as expected, controlling the input signal’s gain as it enters the power amp. The voicing filter is a complex, variable-frequency response curve that is essentially flat when it’s fully counter-clockwise and progressively more 'smiley-face' as it’s rolled up, with boosted bass and treble and a progressively attenuated midrange at higher settings. Input governs gain at the J-FET-based first stage and couples with the o/d indicator to precisely monitor overdrive.

My benchmarks were a Fender Road Worn Jazz Bass strung with DR Strings flats for the old-school side, and a ’74 Jazz loaded with a first-generation J-Retro preamp and spankin’ fresh Dunlop Marcus Miller strings to represent the modern thing.
