This is a Kustom Sienna 35 acoustic guitar amp, fully tested and working as it should. It’s a pretty useful little acoustic setup because you can run a guitar and a mic or second instrument through it at the same time, with separate controls for each input.

The Sienna 35 puts out 30 watts and gives you a 4-band EQ, feedback control, and eight built-in digital effects. The effects include room and hall reverbs, chorus combinations, and slapback, so there’s enough here to add some space and character without needing to bring a pedalboard along. Kustom’s original specifications list it as a two-channel, MOS-FET transistor amp with an 8-ohm output. 

One thing I like about these is the look. The aged brown/tan textured covering, brown grille cloth, matching knobs and hardware give it a much more vintage feel than a typical black acoustic combo. This one has some normal cosmetic wear from use, including marks on the corner protectors and rear panel, but nothing that takes away from the overall look. The photos show the condition closely.

Around back you also get an external speaker jack, line output, headphone output and footswitch connection, so it has considerably more flexibility than a basic practice amp.
