Anybody tried the Rockman Bass Ace Headphone Amp? I was going to get a good pair of wireless headphones and a wireless setup for my bass so I can play in the living room while the wife watches TV. Ive been getting that "you need to spend more time with me and less time in the office with your bass!". Old married guys, you know what I mean. Younger single guys, its coming soon. Only thing is it will cost me about $400+ for this rig, so Im considering a cheaper alternative with this headphone amp. Anybody tried it? Any good?
