East J Retro 01 Fender jazz bass preamp retrofit

GuitarsCorner.com

The East UK J-Retro 01 preamp is an elegant, sophisticated and musical preamp for J-style basses, incorporating three bands of flexible EQ designed to work harmoniously with the natural sound of your instrument. It is also designed to fit directly into standard "Jazz" style basses without modification, including sufficient room for a standard 9V battery. Screw terminals on the circuit board are used for pickup wire connection, making for nearly solder-free installation. A very gentle EQ contour is built into the preamp, adding immediate colour and presence to your bass without detracting from or unduly modifying the fundamental tone. Controls consist of three stacked knobs and two switches. The stacked knobs function as Volume/Blend, Treble/Bass and Mid/Frequency. The first stack controls volume (upper knob) and active blend (lower knob). The active blend has an indent to indicate an equal mix of both pickups. The active nature of the blend also continuously compensates for the level difference between the equal pickup mix and the full clockwise and anti clockwise single pickup positions as the knob is turned. The result is that the playing dynamics are firmly in your hands, not in the pickup output level. The second stack controls treble (upper knob) and bass (lower knob). The treble control is boost and cut at two different frequencies, and is indented at the 'flat' position. Boosting treble gives a maximum of +12dB at 3kHz, while cutting treble gives a maximum of -12dB at 1kHz. Cutting at 1kHz gives a deeper sound when treble is rolled off, closer to a passive tone control than an active treble control. The treble control is also a push-pull knob that controls a bright boost of +8dB at 7kHz, for serious sizzle. The bass control is boost only with a non-fixed progressive variable frequency. Rolled fully anti-clockwise, the bass control is 'flat). As the knob is turned clockwise, the frequency of boost gets progressively lower, to a maximum of +15db at 50Hz. The bass knob is indented at the midway point to aid in setting this control. The first switch (by the Volume/Blend stack) controls the function of the blend and can be switched between full active blend (via blend knob) or a passive equal mix of both pickups (bypassing blend knob). The second switch is a "get you out of trouble" switch that bypasses all active circuitry in the preamp, useful if the battery dies but also handy for true passive tones. In passive mode, all controls are bypassed except the volume and the first switch. The first switch in passive mode acts as a pickup selector, switching between the soloed bridge pickup and and an equal mix of both pickups. Note: The J-Retro 01 Preamp requires a control cavity that is wide enough to accommodate a standard 9V battery, and ideally a minimum depth of 32.5mm.
