Alright, I have a JBL 600.1, used for maybe one month, with MAYBE 15 hours on it. Great condition, has box and almost all papers with it. I was wonding if this would be a good trade, my JBL 600.1 for an USAcoustic 2150 model amp. I posted this to see what you guys thought, and would maybe consider this trade in a few months, but I wanted to see what you guys thought. I need an amp with a filter and higher wattage at 4 ohm load, and this amp is roughly the same price and does about 150 more watts at four ohms. Just wonding thanks all.
