The J-RETRO 01 is designed to fit directly into standard "Jazz" style basses without modification, including a PP3 battery, in most cases. Its high quality circuit uses three stacked knobs and includes an active blend circuit plus a 3 band equaliser with bass, variable frequency mid, treble and bright function.
A very gentle built in contour gives immediate colour without detracting from the basic sound of any bass.
The active blend circuit prevents the loss associated with many passive basses where, when both pickups are up full, the signal from one pickup feeds into the other and vice versa.
However, a switch is included to allow a passive equal mix of both pickups. A second switch - basic "get-you-out-of-trouble" passive mode is included in case the battery dies in crucial circumstances, and this mode allows some useful settings too.
EASY TO FIT, NO ROUTING OR MODS TO MOST J STYLE BASSES.
A STANDARD PP3 BATTERY FITS UNDER THE PLATE IN THE STANDARD CAVITY IN MOST CASES.
HARDWARE OPTIONS: Chrome, Black or Gold. (Can be mixed by special request)
PRE-SHAPE or FLAT RESPONSE
There are two versions of the J-Retro, the original with a slight low and high end pre-shaper boost built in. And by consistent requests, a flat response unit, where when the controls are set in their most neutral setting, there will be no coloration, or difference in response, when switching between active and passive. The standard pre-shape unit gives a slight lift and fatness with a slightly brighter top end, whereas the flat response type retains the original sound, except that the pickups are buffered by the preamplifier of course.
Some players go for more of a bridge pickup mid rangy sound, so the flat response is a better starting point. Otherwise, they have to dial out the pre-shape to some extent. Some prefer a fatter fuller sound in which case the pre-shape gives a head start. The pre-shape isn’t exactly dramatic in any case, with just a few dBs gentle boost at the low and high end. So you can get either style of sound from both but depends where you want to start from. They are just slightly different starting points.
