The new GTO is the latest design coop with Guthrie Trapp. The original was sort of the Nashville favorite, recreating the old Nobels ODR-1. A great sound in itself but Guthrie wanted more! The new GTO has a much tighter bottom, less gain and more cut in the mix. It can go from super mild to a really nice, dynamic OD feel. This pedal has compression but in a great way. You can use it as a clean boost and EQ or you can bring in the dirt. Level – Interactively controls the overall output. The more gain, the louder it will become so you have to use the two in conjunction Gain – Controls the gain level but also creates compression and feel. It blends with the clean signal so you can really find interesting sounds Accent – Controls the cut through the mix, the top end and the bite Warmth – Controls the bottom end but is also very interactive with the Accent control. You can really fatten up the mids but use the accent to keep it from getting woofy.
