I've collected these AMT preamps to find the one or two that work best for me and thought others might like to hear a baseline comparison. The first part of the video demonstrates all pedals with the controls at noon, the second part are my own preferred settings for the riff being played.
With enough interest, I'll also do videos like this for my medium-low gain and clean preamps.
The guitar I used was a PRS McCarty which I ran into a Pigtronix Infinity Looper to record the riff. The only thing after that was the AMT pedal being tested, a slight reverb from a Strymon BigSky and then into the fx return of the Mesa Boogie amp.
