Yamaha DTXpress/DTXplorer/DTXtreme

OK... I figured out how to do a factory reset , but that did not 
help.... it still sounds really low volume, and the bass drum is 
barely there, even when the volume knob is cranked , and still sounds 
like a weird reverb setting yet i tried to change that too... to no 
verb , but still sounds like im in a tunnel i hope i did not spend 2 
grand for this thing to poop out on me not even 2 mos after getting 
it. i still dont even know wht happened , as i saud before , i was 
fine , i took a break come back hit them and poop...dag blurnit.
thanks for your time ... Jaymz Hughes
