This is everything I expected of a rangemaster clone. Makes all my guitars sound much better (except my strat into the hudson broadcaster, that is the combination that just never sounds good). But if you send a trat to a tubescreamer via the ranger booster, you will get some of the best single code blues tone you will hear. And with humbuckers it just screams hard rock.
I thought the price was a little high for a boost, but looking around all rangemaster clones are in the same price range, and this one comes in a beautiful casing, really good quality, totally worth the money.
