Ive got a JVM 205 head through a 1960AX cab. Ive owned the JVM for 6 months now and still cant work out how to use the f ing thing. I just cant set the volumes (within the same mode/channel) to be equal. You lower the volume say on the green OD channel to get a nice moderate rythm volume -and that immediatly effects the volume on the other 2 channels...and the same goes for the masters...bring them down or up depending on what channel your using and all the others are affected. Its a pain in the ass amp and now hate its multi channels. I can see why most pros use single channel amps, or an amp for each sound they want. Waste of dollars.Should have gone for the Vintage Modern - far simpler and cheaper! Mick Northern Rivers NSW
