Guitar pedal effect - boost/overdrive from Andy Timmons signature series. In 2016 JHS releases one of the most popular drive pedals over the last few years the AT Andy Timmons Angry Charlie style overdrive pedal. Now they are cranking it up a notch with the AT+, the same amazing overdrive pedal with an added boost section. The new boost section in the AT+ is a completely independent single control boost that you can kick in at any moment with the dedicated footswitch. On it's own it provides a little bit of grit, pushing your clean sound a bit up to a light crunch on some amps. Combine it with the AT drive inside though and you can take that amazing overdriven sound into a sweet sustaining lead that pops out of a mix.
