To be fair first act is a legit company with some solid guitars. Started with a ex Gibson employee (if I remember correctly) then put out the cheap starter stuff. But numerous artists have first act guitars. (Now if they use them or not idk.) but Keith Richards, Rick Nielsen, Brad Whitford, both the Mastodon guys.
Like I said. Can’t say if they get much use (I know one of the Mastodon guys has a First Act custom 9 string that got some real use) but they do make decent guitars
