Electro-Harmonix EHX Hot Tubes Overdrive Effect Pedal

Electro-Harmonix Hot Tubes Overdrive – Tube-Style Warmth | Tone Switch Bypass | True Bypass | Vintage-Inspired Dirt

Description:

Tube Tone. Solid-State Reliability.

The EHX Hot Tubes delivers the warm, responsive overdrive of a cranked tube amplifier in a rugged, compact pedal. Designed to emulate the natural breakup and harmonic richness of a tube amp pushed to its limits, the Hot Tubes produces everything from subtle, bluesy grit to thick, saturated distortion—all with exceptional touch sensitivity and dynamic response.

The intuitive three-knob interface makes dialing in your perfect tone quick and effortless. The OVERDRIVE knob controls the amount of gain, ranging from mild tube-like breakup to full-on saturated distortion. The TONE knob allows you to shape your sound from warm, rounded lows to bright, cutting highs. The innovative TONE SWITCH bypasses the tone control entirely, delivering a more powerful, direct signal with enhanced punch and presence—perfect for cutting through a dense mix. Housed in a compact chassis with true bypass switching, the Hot Tubes is a versatile, affordable addition to any pedalboard.

Key Features:

• Tube-Style Overdrive: Emulates the warm, responsive breakup and harmonic richness of a cranked tube amplifier.

• OVERDRIVE Knob: Controls input gain and distortion—from mild tube-like breakup (fully counter-clockwise) to saturated distortion (fully clockwise).

• TONE Knob: Creates a range of tones from warm bass to bright treble as the knob is turned clockwise.

• TONE SWITCH: When set to OFF, the Tone knob is disabled, resulting in a more powerful, direct tone with enhanced punch. When set to ON, the Tone knob behaves normally for full tonal shaping.

• VOL Knob: Sets the output volume, providing ample boost for solos or driving your amplifier harder.

• True Bypass Switching: The footswitch engages or bypasses the effect. When engaged, the LED lights up for clear on/off status.

• Compact & Pedalboard-Ready: Small footprint design fits easily on any pedalboard.

• Vintage-Inspired Aesthetic: Classic EHX styling that looks as good as it sounds.
