  1. Treble/Bass Stack

Add active EQ to your P or J without any drilling with this 2-band onboard active EQ with stacked basstreble pot, and switchable treble frequency.

On board Tone Circuits add tremendous tonal versatility. This circuit enables you to boost or cut EQ at center frequencies voiced specifically for electric bass. Features low noise, low distortion and high headroom. Originally voiced for use with Blackouts for Bass but with its switchable treble frequency, works well for all musical styles and genres.The lows are deep, clear, and tight. There are two treble frequency centers to choose from. The lower setting is perfect for adding growl and bite to traditional P, J, and MM tones.

The higher setting provides crystal clear top end to modern-sounding, full-frequency basses, and when used with Blackouts for Bass gives punishing clarity without being brittle.This two-band active EQ is available in two configurations. This STC-2C-BO is mounted to a concentric potentiometer, and can replace a standard tone knob with no need for additional holes in the bass; while the STC-2S-BO separates the treble and bass controls onto two pots.

For nearly all basses, due to the selectable treble frequency. For use with active or passive pickups.

Very good for the price I installed it on a Squire P-bass and it brought the sound to another level.
