Hey I've taken my little roland microcube to my friends house and when I put it on the distortion channel for example, it seemed like alot of the tone was sucked out of it. Could this have to do with the grounding in his house? Because it sounds better while at my house.
Acoustics of room maybe? Could be your position relative to the amp as well.
The room you're in can play a surprisingly big role on the tone of your amp. Which I find annoying tbh.
hrmph..well if thats the case then that sucks :\
