Details

The U-RETRO 01, based on the J-RETRO 01, is a universal highly flexible on-board dual input preamp and EQ system. 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 passive tone, which interracts directly with the pickups, operates in both active and passive modes.

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 as this can give a subtle difference in sound. A second switch allows some basic passive modes with some useful settings too.

Each pickup input has its own individual input amplifier, along with its gain trim adjustment preset. This allows for pickups of different types and output levels to be readily matched without compromise.

The pots have 10.0mm threaded bushes designed for rear cavity mounting in the bass. Flat wire connections to the pots and toggle switches allow for flexible layout.

The preamp comes fully wired including battery clip and Switchcraft jack. For ease of installation, pickups are connected via screw terminals.  A ground wire will need to be connected to grounding points such as the bridge and any internal screening.
 
Out of the box, just connect the pickups using the screw terminals. snap on a battery, and you'll get sound. 

HARDWARE OPTIONS: Chrome, Black or Gold. (Can be mixed by special request)

What they say!

*  Hi dear John, This message to confirm all the pleasure I have to play my Alusonic bass with the perfect wedding Crel pickups and your U-Retro Deluxe preamp; It's really the sound I need and I hope. The most important point was the continuous medium frequency setting; I've choosen one which give me a punchy sound and a lot of presence. The other characteristics I appreciate are also the cautiously bass and treble settings. Treble frequency is perfect to add relief for slap style without the strings noise on fret,and it's very easy when playing,to find a smooth sound cutting treble or medium. Bass setting is flatbecause the instrument give natural rich round sound on B and E strings. Again bravo about your work. With my best musical regards.  Patrick - France

*  Hello John, my name is Julian and I bought a U-retro bass preamp which I love. I used in in a Warwick Corvette bubinga bass. First I used the stock gold/active pickups but being a rather 'clean sound' person I wanted to see how my Bill Lawrence J-45 pickups would sound with it and I liked them both.  Julian - USA 

*  Spent some of the weekend fitting the U-Retro as well as making sure the cavity was properly and 100% shielded with copper sheet. It was pretty easy although I had to re-use the existing jack rather than the one supplied - shame as my soldering skills are awful. The end result though is that the guitar sounds brilliant, as well as quiet, even with treble and bright boosted. Frankly, it's like having a new guitar but a whole load cheaper. I can't put the thing down I have already managed to annoy the family by playing too much and too loud!! Many thanks.  Huw - UK
