The Country Guitar has been a popular hacked DLC 'axe', known as the Guitar Axe.
I have recently re-released it as a permanent HDLC (called GuitarAxe2)
----
There are 3 other guitar furniture items built into the game: Rock, Metal and Folk Guitar.
I've taken off the guitar stands and turned them into similar GuitarAxes. You can use them to hit your friends over the head.
Please take a look at them and let me know what you think (please post on this thread or PM/email me)

Also a test version of EZ_DLC_Install is available to try them as "OHDLC". You can try 2 of them at a time.
If worthy, I hope to release them soon as separate (permanent) HDLC.
IMHO the 'folk' guitar is too similar to the 'country' guitar, but your opinion counts.
