I am going to try one, with my Gretsch 5129 fat body (DeArmond single coils) and my Vox AC-15. I see the new version has a boost. Is it effective/useful?. Or should I save a couple of bucks and shop for an older version? I am looking for something that is going to retain that Vox grind and chime. I've been using (not all at the same time) a Fulldrive 2, a OCD, and a RC Booster, all with pretty good results.
