defnition of Beater guitar = something you dont give a shit about and can use and abuse. cheapies with mods? partscasters slapped together? abominations of nature...
the cheaper the better.
GO!
mine
squier Vintage modified Custom neck/15+ year old Samick Strat body from my very first electric guitar...refinished in 2pak paint, and abused/mistreated and forgotten, stored in a tin shed (aussie summer gets to around 40 deg cel) pickguard holes dont line up, bridge pickup is a from an ibanez (infinity INF4) and neck is a GFS 90. slapped together and a few tweaks here and there...and i can play just as good on this guitar as my other much nicer guitars. another tool to make some noise with! i love it!
