It's perfect, i would add more adsnese at the top right (check out the adsense here in the thread right between my post and yours). About the site in general, if you want any traffic you should start posting unique contnet, articles about fenders, and music. You can just use a ebay script and expect visitors to come. GOOD LUCK
Actually, I would remove the 2 468x60 ad units and have them randomly placed where an auction listing would appear, would get much better results.
