I bought this amp new so my son and I could play together. We have barely used it and both have Fender tube amps now, so we don't need the Crate. It has never been used outside my smoke-free home and looks brand new. Includes the owner's manual, original box and all packing materials.
The amp has two independent channels with inputs and controls for each: Volume, Clean/Overdrive switch, OD Gain, Treble, Mid, Bass, OD Level, Effects. You can play two guitars at the same time through the amp, controlling tone and effects for each one separately from the other.
The eight onboard effects to choose from are: two delays, flange, two choruses, chorus and reverb, and two different reverbs. 50 watts through one 12" speaker.
I don't have a digital camera, but here is a link to a couple pictures of the identical amp.
Crate's online manual will show you the specs for the amp. I am asking $300 for this nearly mint condition amp, but will consider trading for pens (let me know what you have).
