FS: Used GK Backline 600 Bass Amp. I've had this for approx. 2 years. Used for VERY light gigging (less than once every 3-4 months) and light home practice. Unit functions perfectly and is in great cosmetic condition. 300 watts @ 4 ohms 13 lbs 4 band eq Gain, boost and volume controls Contour control Seperate Distortion Channel Effects loop DI on front GK links: http://www.gallien-krueger.com/products_bl_hd_600bl.html http://www.gallien-krueger.com/products_spec_600bl.html Asking $200, paypal ok. Open to hearing trades. I'd really like an Ashly 571 para eq though, and random effects pedals are always fun. But I really looking for the cash on this one. I can post pics upon request.
