I just got my first bass, but since I ordered my amp online (and the shipping's taking quite awhile, something I need to call about), I had nothing to play on. So, I figured that I'd try it out with my old guitar amp, a Crate G15XL from a guitar setup which my parents got completely ripped off for two years ago and gave me as a gift. Now I don't know if I'll be using that bass amp much when it gets here... with the Crate, I can bring the volume up to 11 and get some nice, fun distortion. But using the built-in distortion switch on the amp, it makes Zeppelin's Dazed and Confused really fun to play. And the speaker is holding up very well, no signs of damage when I turn the volume down and eliminate the distortion. Very nice little experiment of mine, makes me (almost) glad Sam Ash is taking their sweet time getting the amp over to me.
