The NOLL TCM 3 is a compact equalizer that provides easy and space-saving installation. 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 TCM3 includes the concentric Volume (Push-Pull Active/Passive)/Blend, jack, and battery clip. The concentric Treble/Bass, and Midrange controls are prewired with high flexible cables.

Please Note:

    Exactly what I needed
    By Gage
    Used this preamp in a Warmoth build. 32" scale P/J, mahogany with maple cap and Wenge neck. I ran the Noll at 9 volts with Bartolini Classics. The sound is excellent, frequency centers suit me well and offer a ton of options. This is literally the best sounding bass I've ever built or played. The preamp is pretty colorless.....switching back and forth from a flat-set active to passive yielded little difference. I literally wouldn't change one component, as the sound is so perfect for my needs. Slap to fingerstyle to does what it is supposed to do. I would highly recommend this setup to anyone. Mec pots, superior quality, nice work Noll.
