Re: Turning a JB into a Distortion?
It could be the roasted peanut...err..maple making it darker. Either that or there's a bad pot. Your Tone may be sticking at a lower setting, even though the knob is on 10. Wire straight to the jack and add pots until something changes.
As was stated, the JB and Distortion do not have the same wind. IIRC it was stated by one of the current/former SD peeps here (was it Frank?) that they use different wire sizes, have a different wrap count, and are simply voiced differently from each other.
What you can do is put a ceramic magnet that is the dimensions of the A5 in the JB (i.e. take one out of a Custom and put it in the JB) and it will sound "Distortion-ish" but will not be a true Distortion. It's commonly called the DistortionLite, or JB+. A little more drive than a stock JB, but not as much grind as a Distortion.
Frankly is you want a better Distortion with more articulation, get a PATB2. It's a lot cleaner, but still delivers the pizza.
