The Euphoria is his take on that elusive tone and feel made famous by "D style Amplifiers" - smooth creaminess yet crunchy when you need it to be, yet the tonality is much more transparent than other "D sounding" pedals. Very responsive tone controls that interact with the pedal - they don't just "color" the sound. The controls actually affect the response and feel of the pedal, just like a great tube amp. If you love the sound of your clean tone, and just wish you could have more "hair" on the note... a little bit of grit without any change in tonality, the Euphoria will do that with ease. PLUS it's extremely flexible... with the toggle switch in the down position you'll get a hint of fuzz along with the overdrive, it's reminiscent of the tones that "Eric Johnson" may use. With the toggle in the up position the tonality is super smooth, creamy yet crunchy when you dig into the strings. This is reminiscent to the famous "D style" tone, though it's really much, much more than that. In the center position, the toggle will give you tons of crunch, or roll the gain back a bit and push the volume up and you have a superior clean boost with a 2 band EQ that's extremely transparent, but variable so you can actually turn it into an awesome treble booster just by cranking up the treble and turning the bass down.
