The new boost section in the AT+ is a completely independent single 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. This boost is set just before the drive in the circuit to push the drive when both sides are engaged.
If you loved the original AT @ Andy Timmons drive then you will love this as the main section of the pedal is exactly the same, unchanged from the winning formula they had before. Same controls, same feel, same tone just now with an added boost section.
If you have never heard the original AT what can you expect? This is an amp transformer, it works great with any clean or crunch tone and turns it up to 11 with a great american style drive.
