near me are the following
music 101 - second hand instruments for beginners, good shop, decent prices, nice guy.
billy hyde - massive range, they dont seem to mind if you just pick up some of the guitars and play heaps, the prices seem OK (i was once gunna buy a ltd ex-400 off them for $1500, which is $100 more than venue music in the city sell them for), but if you're good at talking you can usually talk them down a bit anyway. this joint managed to put guitar world out of buissiness in paramatta road lol ;D
gallins guitars - gibson (and epiphone of course) and some matons store only. expensive because the guitars are good quality. (bar the epiphones ;D)
downtown music - dunno about the prices, but for a small store they have some pretty cool guitars. last time i walked past they had a clear bc rich warlock =]
ive also got the bass player and 'sydney guitar setups' close, i dont play bass so ive neverb een into the bass player, and sydney guitar setups is more of a maintenance place i think.
anyway i hoped that helped, its the longest post ive ever done D: and this is all on paramatta road annandale/stanmore. all of these guitar shops are like within a 200m space.
