DESCRIPTION

The J-Tone is a new on board preamp with a fully passive signal path and a high spec professional active preamp. It is designed to fit directly into any jazz style bass without the need for invasive modification to the instrument. In passive mode, the original jazz style bass is fully maintained since the signal path is a replica of those in the original Jazz.

The J-TONE pre amp was created to replicate 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 Active EQ is simplicity itself, incorporating highly responsive bass and treble controls, taken from the John East 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.
