This amp has built in FX, with the ability to program specific FX. External speaker out and additional insert located at the back. Three channels lead, rhythm, and clean all have great sound and covers a wide range of tones. The original owner's manual and foot switch are included in the sale. I used this amp for my high school jazz group and got the job done. This amp is literally sitting in the corner of my room not being played since I've bought another amp. The Crate is in excellent condition and working order. This amp would be perfect for a progressing guitarist looking for the next step up. Please contact me if interested, I'm willing work something out. I'm a college student and I need the money. I'm asking $400 OBO.
