Wasn't me. I've only seen, played and set up the Maverick that Jim has...
If i see it again on evil-bay, i'll PM you the link if you want cos although it's uout of my range; it may not be out of yours.
Do you know Jim's tech- Martin Connors?
Dude is HUGE! I never saw him next to Jim, but he must be at least 6'5". I wanted to get his as well as Jim's autographs when Stone Sour played the London Astoria (i got Josh's) but they disappeared.
I think Jim was bursting for a ****! Lol.
EDIT- I gotta say that IMO the JR4 plays excellent. I've set it up & done soe mods so it isn't "off the shelf", but with my mods it is great. I love the tone & with the EMG's it kicks metallic ass!!!!!!
I can play on it as fast, smoothe & clean as my RG1550. Ideally i'd want number 2 of 2 of Jim's actual guitar cos it's Alder bodied i think, with Ebony board.
It doesn't have active EMG's though which is dumb if it IS Jim's guitar.
But i can say 100% hand on heart, it plays better than any Fender USA of High End Gibson i've played, which DO include the really expensive ones & also a Flying-V like Jim was playing on the Astoria gig.
