« Lives up to the hype! »

I use the JF-02 with Fender tube combos, Silvertone tube head and a Marshall 18 watt combo. Battery is easy to change. I have tried this pedal with my 1962 Strat and Epi-Dot. I don't know how power hungry it is yet. I do intend to try it at 18 volts. I expect that it will increase headroom even though it already does the clean boost thing superbly. At 9 volts and the drive control at minimum, clean tones and the guitar's character really comes through. At about 9 o'clock a little dirt starts showing up. (with Texas Special single coils at about 6.25 K ohms). Between 9 and 12 o'clock you get slight to medium overdrive. The touch sensitivity is on par with more expensive boutique ODs. Still the guitar's true character is heard. Past 12 o'clock is dominated by moderate distortion. Throughout the range of the drive control you can clean up your tone by rolling back the guitar's volume a little bit. The tone and level controls are musical and effective. Bottom line- this thing is outstanding regardless of price! I love to modify amps and effects but will be leaving this one alone.
