PREAMP FOR BIGTONE: Schertler Stat-Pre or Pre-A III?

I have a Schertler Unico and just wanted to know which one of the two Pre-Amps could be used for a bigtone pickup, as it doesn't get very loud when plugged directly into the Stat- channel of the Unico.

Any help is greatly appreciated.

    The Unico itself has those features built-in, so I dont think the pre's will be of any assistance really. What I would get that I use with my bigtone/unico combo is the schertler active driver cable, it really makes a difference.

    For the connection of passive pick-up systems requiring high impedance input (passive piezo systems, ellectric guitars and basses with magnetic pickup). Active Driver Cable is a mono Jack with one side modified electronics for rising input impendence. Using it with a Unico amplifier, input impedance is near to 500 Kohm. The red connector is the active one, plug it into your amplifier Jack input (Stat In).
    Order code : CA-ADRIVER-4

    Also, be careful of losing volume by cutting the amps eq's too much. You can lose lots of volume by cutting the treble for example.

    Hey, thanks for the reply.

    The thing is that I have the bigtone built into the bridge by german luthier Jürgen Volkert who has a vast experience with maccaferri guitars ( The bigtone is set a bit deeper into the bridge, not too close to the strings. This greatly improves the tone, but also implicates a loss of output gain (like the Bigtonde deluxe setup sold here at So I thought to compensate it with the Preamp. So do you really mean that the Preamp doesn't improve the outpout volume?

    But thanks for the cable tip, I'll try it out!
