    J Tone 01 Pre Amp John East – Bass

    Is it possible to retain the original sound of a J style bass?, but with a modern Active EQ? in the same preamp, along with no changes to my bass?

    In response, we have created the J-TONE pre amp, replicating the authentic original passive wiring of the J style bass with a high spec Active EQ. It's designed as a direct drop-in replacement, including a place for the battery. It's easy to fit at home using basic tools, no soldering, no physical changes to the instrument*.

    The Passive wiring is available as either the classic Volume / Volume / Tone, or for those who prefer a master volume – Volume / Blend / Tone. Plug-in tone caps allow additional fine tuning of the passive tone control.

    The Active EQ is simplicity itself, incorporating highly responsive bass and treble controls, taken from our new high end UNI-PRE system. Internal edge wheels allow individual custom voicing for both the bass and treble control spectrums. Instrument qualities can be enhanced in conjunction with tone-shaping to match playing styles.
