Onboard Preamp
TCM 2

The NOLL TCM 2 is a compact equalizer that provides easy and space-saving installation. The secure insulation of the sealed equalizer perfectly protects other electrical components. Bass 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 equalizer is 9-Volt battery powered, adding an additional 9-Volt battery (18V) will ensure more headroom and longer battery life.

The NOLL TCM 2 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.
