Micro-pedals are all the rage and finally you have a proper attempt at a micro-expression pedal. Overall this is a just an incredibly clever and pedalboard friendly little option.
The AMT Electronics R-1 Preamp is made to emulate the sound of a Mesa Boogie Dual Rectifier, and boy does it ever! I was amazed at what this $200 box can do.
The knobs and buttons are self explanatory. The top row of knobs are Channel A, or the clean channel. The second row controls Channel B. Bass, Middle, Treble, Gain Crunch and Gain Lead.
The WH-1 is a wah goddammit, it's the easiest type of pedal to get a good sound of once you get the hang of it.
