I've owned the Barber Direct Drive and Signa Drive. You will be very pleased with either. the Barber is very transparent (overused term, but best I can think of). It gets quite a bit of drive if you need it, but the low gain is exceptional too. One of those pedals that sounds right with any guitar amp combo. The Barber LTD is similar with less drive. Built exceptionally well, made in USA & priced right.
The Signa is very organic too. Neat thing about it, is that it has a mini-toggle, which runs the input through 3 different chips. As I remember, one is TubeScreamer-like, one is lower gain but with higher output, and one is high-gain more like hot rodded Marshall sound. Built exceptionally well, made in USA, and again - good price for what you get.
Never heard a Pinnacle.
Best of luck.
