Boss DS-1 Fat Mod (by AMZ-FX)

Back in 2008, Jack Orman had posted a mod for the Boss DS-1 that helped make newer ones sound sweeter and not so harsh. At the time I had a few laying around and decided to give it a try. Yeah, that did the trick. It made it sound like a DS-1 should.

See, the problem is the input stage gain is too high. This mod fixes it by dialing back the gain. All it takes is changing two resistors. One to dial back the gain and the other to rebias the transistor. Very simple.

It may be 6 years later, but I feel it is worth sharing.  Thank you, Jack.
