I just got my first electric and a Roland cube 20x some two weeks back. This evening I turn on the amp and find that the volume is extremely low even when cranked up to the max. I'm ****ing panicking right now because I really had to push my budget for this amp and now it looks like I'm screwed.. And also I left the plug switch on for two days, but the amps switch wasn't turned on.. Any help would be really appreciated. Please help
