Debug a TS808 no gain - Deadhorse by Protone

[spunko]

Hello friends, this is my fisrt post here.  
I have a Dead Horse by Protone that bougth from ebay, it's supposed to be a TS808 clon with symetrical/asymetrical diode clipping. When I tryed it, didn´t have much gain, in fact it was like a clean boost with little gain at 100% all knobs, I tryed batteries and two 1spot.
I thought it was modded to be a clean boost, then I saw that the led was a different color (green) from the orginal (red), so I oppned it again, and saw that the Drive knob was 160K, instead of a 500K that the schematics show. I changed the knob and the led for a red and 500k and it worked, when I first tryed it sounded like a OD pedal, with a lot of gain \m/. Then I took off the power cord and plug it again for more testing, and sadly it sounded like a clean boost again, almost no gain. After more testing, the pedal works randomly, sometimes I have to plug/unplug the power 4 or 5 times because it truns on with no gain. Somtimes will turn on with normal gain at the fist try.
I don't have much technical knowledge, and can't figure out the problem here, I hope someone help me to solve it. I have a fluke multimeter, soldering skills, and a lot of patience
Sorry for my bad english.

This should be in the "Building your own stompbox section".

As the forum subtitle states, this section is for digital and dsp related problems.

Sorry, I didn't know that. Could someone move it to the "Building your own stompbox" section, or do I have to start a new post?

Thank you.
