Glowplug Tube Warmer

OVERDRIVE

BOOSTER

PREAMP

Description

Housing an authentic 12AX7 preamp tube, this harmonic enhancer pedal introduces vintage warmth, natural compression, and subtle overdrive saturation to bass signals. A dedicated crossover control sets the frequency threshold from 100 Hz to 1.3 kHz to restrict harmonic enhancement strictly to low and low-mid bands. Instrument definition remains intact via an interactive mix control that blends uncolored dry input against the warmed tube circuitry. The warmth potentiometer dials the tube drive from gentle harmonic enrichment up to gritty edge-of-breakup saturation. An integrated volume pot supplies ample output level to serve as a clean or saturated pre-amplifier boost. Signal routing employs true bypass footswitching in a folded heavy-duty steel stompbox enclosure.
