Harmony H620 Tube Combo Guitar Amplifier
At the heart of the H620 lies two 6L6 power tubes and three 12AX7 preamp tubes. This amp delivers 20 watts of warm lows, rich mids and glassy highs through an Italian-made 12" Jensen Falcon speaker.
Other key features include a 3-band EQ and a Presence knob for precise tone-shaping adjustments, along with a built-in attenuator that allows the H620 to use its full tonal capability even at lower volumes. Onboard Tremolo, Reverb and Gain Boost are foot-switchable, and a line out jack is also available for direct recording to an external device.
Smooth, responsive and dynamic, our Series 6 Amplifiers feature all-tube circuitry for signature cleans and saturated tones.
A Standout Design
All amplifiers are wrapped in deep blue tolex, complete with an angled baffle and leather handle, making it visually stunning and always durable.
