Vintage 1961 Harmony 310 External Reverb Unit w Jensen 10 Speaker

  
Heres a link to a demo. Unlike other Reverb units of the era, which came with a Hammond style reverb tank, this EXTREMELY RARE piece, courtesy of the Chicago music giant, Harmony, came with an amplifier section and a speaker.

Using a ¼ to RCA cable (included), this unit plugs into the external speaker jack on your boring old dry, non-reverb amp. Dont worry, if your amp doesnt have an external jack, you can pigtail a jack right off the dry amps speaker leads. Until you activate the footswitch, which is hard wired to the chassis, this unit also amplifies your dry guitar, adding additional depth to your signal. When the switch is engaged, the Harmony H310 soaks your sound with Reverb and sends it to the on board Jensen 10 speaker. Spread the amps apart and dig the great stereo effect with one side dry, and the other dripping in glorious spring Reverb that you can adjust with the Gain and Decay controls.

Needless to say, this would pair quite nicely with a Harmony H303 or H306, and make you the coolest guy in the garage. But this unit, and most Harmony amps at the time, was manufactured by the Sound Projects Company, which was west of Harmonys Chicago headquarters, in Cicero Illinois.

So, youll find this will compliment most Lectrolab amps as well. But it will work with ANY amp of yours thats in need of wetness. But remember, this unit is from 1961, so you may want to swap out the old lamp cord for something a little more safe (grounded 3 prong). You may want to change the RCA input to a ¼jack so youre not relying on one specific cord that youre just gonna lose at a gig. Ive gone ahead and replaced the dried out leather handle, the 2 amp fuse and some missing screws, cleaned the pots, given it a new #44 bulb, glued and clamped one side of the cabinet, and replaced the broken strain reliefs for the footswitch and the AC cord, but it might not be a bad idea to take this to your tech and have him --cuz lets be honest, your tech is definitely a dude-- drop in some new tubes and get those sockets cleaned and re-tensioned.

Do that, and then you can be the REVERB KING OF 1961! Contact me beforehand to work out any other arrangements. "As Is" sale, with all sales final. This unit is currently being offered at Reverb.
