I use a TS9 clone with the + feature and i run the gain low. Imho i an NAIL a Jerry tone with this pedal, pick softly and its nice and clear, dig in and it gets rough. My fav dist/od pedal t use by far. I go back and forth depending on the song with my DOD 250 clone and a GL custom drive. So i have 3 different distortion tones to play with. But the tone i always come back to is the TS9. Im also running a BBE Boosta pedal at all times on about 10am on the dial.
This thru a Fender or my SMS CTP preamp is amazing sounding. I personally dont like the MXR Dist+, i owned a nice 70s one and i just didnt like the tone. May have worked for Jerry, but it didnt like my picking style it seemed. Different strokes for diff folks.
The TS9 sounds wonderful with either my Wolf guitars or my G&L guitars. I can get 70s-90 perfect, after that im not as big of a fan of Jerrys tone. Its not bad, but its not the same. I do like his later clean tone a lot though.
