These little babies were amazing! Add more bass to your guitar by running the low E and A string into a bass amp with a simple configuration. These things add balls to your tone that you didn't know existed! We were were at the NAMM Show workin' the floor when we stumbled onto Andy's booth next to the James Trussart booth. Andy, the inventor and engineer behind A Little Thunder pick ups was there doing demos busting out some classic rock riffs by the likes of AC/DC and Aerosmith. Instantly you could here the bass coming through in his playing. But it wasn't muddy, heavy bass tone… it was clear as a bell! Ok, so i sat down and couldn't help but banging on some power chords… Wow! These things could honk! Heartbreaker Guitars goes to the NAMM show every year and let me tell you something… it is HARD to stand out in a crowd full of incredible gear! My partner and i were simply amazed with the tone of these pick ups! And thats not to mention some pretty sweet James Trussart Guitars they were mounted on! Anyway, best of luck to the guys at A Little Thunder. What a great product!
