Onboard Preamp
TCM 3 P

The NOLL TCM 3 P is a compact equalizer that provides easy and space-saving installation. The secure insulation of the sealed equalizer perfectly protects other electrical components. Bass, midrange and treble controls are center-detented and allow 15dB of boost and cut with a gentle slope of 6dB per octave which results in a natural and true sound. The best feature of this preamp is a parametric control with adjustable frequency range for all controls. With this electronic the player can pretty much dial up any sound imaginable.

The EQ requires power from two single 9 Volt batteries in series (18V).

The NOLL TCM 3 P onboard preamp can be combined with both active and passive pickups.

All units are prewired with high flexible cables, delivery contents all pots, jack and battery clip; however, knobs are not included.

Potentiometers have 6 mm solid shafts, while the stacked pot has 4 mm (upper) and 6 mm (lower) solid shafts.

Our MixPot also allows you to combine high impedance Piezo with magnetic pickups. Further custom configurations are available.
