I play a Mesa Lonestar Special, and my question concerns the clean channel. I am looking for a pedal that fattens the tone, makes it rounder and is able to add a tad of dirt without increasing the volume of the channel considerably. I had looked on Youtube for videos, featuring some devices that might be fitting (EP Booster, Klon-Clones etc.), but the videos left me without a definite answer. Either the volume increase seemed too big, or the people were using the pedals with (for my needs) too much drive. Remember, I have the second channel for more dirt. So, what have you tried for similar purpose that worked well?
