The Harmony Amplifiers - Series 6 - H620 brings an all-tube design with a host of player-friendly features. At it's core is a 12" Jesnen Falcon speaker powered by a trio of 12AX7 preamp tubes, and a pair of 6L6GC power amp tubes. On-board analog effects, including spring reverb and tremolo, deliver loads of classic tones, along with a built-in attenuator which supplies high gain tones at small-venue volumes all the way down bedroom levels. A handy feature includes the ability to turn the attenuator down to zero, allowing for silent recording when running the line out into an audio interface. Plug in a second speaker cab via the handy second output at the back for increased volume depending on the gig. This retro-inspired amp harkens back to some of the cool odd-ball vintage amps of the past, and sports a retro-inspired design which looks good in any space.
