The other day I was trying out some basses and amps at a G.C. I was mostly trying to hear what different amps sounded like but also enjoying different basses. I was playing scales and simple little riffs to try and play in as many positions as possible. I was also checking out different EQ settings on the amps. This older guy walks up plugs in, cranks the amp and starts playing the bass riff for "Come Together" over and over again at ear bleed volume. At that point I couldn't hear anything well I was doing so I hung up the bass and left. I didn't want to get into a volume war with this putz or start playing recognizable riffs that I know. (U2 anyone?) I realized later that I could of gone into one of the quiet rooms but I also would have had to haul each amp I was checking out into the room. I'm sure there have been similar rants here before but I do feel better now. Maybe I should change the thread title to people who think they are showing off at music stores. I'm not surprised when a young kid acts this way and I give them a lot of grace but this guy should know better by now.
