I've not played any Nash guitars or basses so I can't comment on the parts quality. But just looking at the paintwork made me not want to pick them up. I'm sure some are great, but they're not for me.
But I'm not really into relics as such. My Bravewood P bass is a replica of Sting's #1 bass, so it's reliced to look like Sting's as much as possible. My wife's Bravewood P bass was built un-reliced.
What's nice about a relic is another ding doesn't spoil the look of a pristine instrument. I know some people are very fussy about thinga like that. I'm not though. I gig all my gear and if it gets dinged etc, so be it.
