I have a Godin Freeway 4. The 'P' pup has been replaced with a Seymour Duncan Quarter pounder and I've sanded/reshaped/oil finished the neck. It's rather spiffy, all in.
One gripe though. No; two. First: the neck is very noisy (buzzy/rattly) acoustically and a lowish action is almost impossible to achieve. I had a Godin guitar a few years ago which had a similar if somewhat worse problem, which makes me wander if there's an issue with their fret materials or whatever? Particularly odd given their emphasis on the necks being hand built.
The other one is: the bridges on these things are great; you have a standard stringing option or a through-body option. Not much of a gripe so far, right? Well ... this bass was a gift from a friend and he had it strung with some pretty beefy wire, through the body. It sounded great, big bright and clangy (in a good way). But the strings were way to heavy for me, so I got my usual Roto Swing Bass long scales and went about replacing the old strings ... only to find the the Rotos aren't long enough for the through-body option! There's nothing that I could see on Godin's website to warn you of this, but it looks like exra-long scale strings are needed for stringing through the back.
Of course, maybe that's always been the case with through-body strung basses, and I'm just being ignorant. Not that that would stop me bitching!!
Anyway, an otherwise excellent bass - and these things are insanely good value for money to boot.
