It is very similar, but the Persuader Deluxe also has an LED and a mini-toggle boost switch located at the top of the pedal.

Hi! Great product, sounds good! I have a question about the Gain Knob, let's say it goes from 0 to 10. The pot does very little variation between 0 and 8. And then, all the gain is to be added between 8 and 10, which is pretty difficult to dial a precise gain tone... Is it possible to have instructions to obtains a more "linear" gain increase and more subtle, starting sooner on the potentiometer? Is this a resistor thing? Also, what are the mods you suggest If I want to try different types of tones, gain stages with this pedal? Different Mosfet? Different caps? Thank You! Bruno
