Probably not really worth the trouble (but I'm gonna do it anyway ), but I've got a 1990's US made Peavey Microbass combo. It's a nice little amp, but the driver was crapped out when I got it second hand (eBay...). Anyway, I'm not really too fussed about the fact that the driver was gone when I received it - it was nice and cheap. I threw a generic 8" driver in it that I had kicking around, and it's OK - but not fabulous...but would like to replace it with something more suitable. Any specific suggestions on a replacement driver for a 20w Peavy Microbass?
