BigAmp Piezo
Type: preamp/D.I.
Features: Low noise Class A JFet amplifier, 15db amplification, Balanced output, input impedance 5 mOhm, runs on 8-48 v phantom power
The key philosophy behind the BigAmp D.I. is to put the pre-amplification as close to the musical instrument as possible, where it is most effective. An extra benefit might be BigAmp’s really small size, making it ultra portable. It runs on phantom power (from e. g. mixing console).

Sunday Driver
Type: preamp/buffer
Features: input impedance 1 MOhm/4MOhm (switchable), gain control
This little box has not much features, but is very effective: it has a switchable input impedance of 1 or 4 MOhm, which helps to get the best from your piezo pickup. The signal is preamplified without any modification. It is suggested to be used as a impedance matching buffer for electric bass amps (which usually have too low impedance inputs), as a cable driver for large stages, in complex effects set-ups, or as a recording preamp.

Series 3
Type: preamp
Feautures: volume control, adjustable high-pass filter, Input impedance / capacitance: 10 MΩ / 220 pF, Phase (polarity reversal) switch
This preamp was developped and is manufactured as part-time business by bassist Francis Deck. He doesn’t sell to outside the US: “Unfortunately, the world still has borders. The HPF-Pre product does not carry a CE marking. There may be other countries where the lack of regulatory approval is also a problem. While I am confident that the HPF-Pre would be approved if tested, the cost of testing runs into the thousands of dollars. This is simply impossible for a very small business.”
However, Francis makes the schematics of his preamps available to public for DIY projects.
