With a rich and distinctive sound to its name, the Harmony H650 combines the best amp-building techniques of the past and present into a single neat package. Made to stand out at festivals and concerts, this amp delivers a multitude of tones — from signature cleans and edge-of-breakup tone, to all-out roaring leads.

At the heart of the H650 lies two 6L6 power tubes and four 12AX7 preamp tubes. This amp pushes 50 watts of warm lows, rich mids and glassy highs through an Italian-made 12" Jensen Tornado Stealth 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 H650 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.
