Arlington GC is pretty decent, because they have vast stock of MM/Fender and they also have Rics and super vintage fenders. otherwise, Craig's in Weatherford is stocked with Mesa Amps, and thats it. if you want a bass experience, go to Bass Emporium in Austin.
yeah, Dwayne is the manager and he's a really cool cat (bass player too) otherwise, i like murphy's music in irving, although they don't have a lot of bass stuff...they're cool guys
