Last week I found this pristine BOSS SD-1 Super Overdrive at a pawn shop for $15. It was the lowly made in Taiwan model, not the spendy vintage MIJ variety. Strange as it sounds considering that I've been playing guitar for thirty five + years, I don't recall ever trying one of these before. I think that a negative experience with a BOSS DS-1 Distortion sometime way back put me off to the brand. But for $15 it was a no brainer. So I buy the thing, take it home and fool around with it all weekend, reaching a number of conclusions and raising a few questions. First, holy hell this thing sounds good . . . like really good. I've got boutique drive pedals, hand wired stuff and so on, so I have good standards of reference to compare the BOSS with. The SD-1 is warm and natural sounding but also detailed. It works awesome as a clean boost with the level maxed and the drive pulled way back. With the drive set just shy of 12 o'clock it has such a nice gritty snarl. It's more rude than a Tubescreamer, in a good way. I've never liked a Tubescreamer for rhythm, but this SD-1 does a great job at it. So my questions: Why in the world are these only $50 new? Do you guys think this one has been modified? It definitely doesn't lack low end or have that "blanket over the amp" sound many attribute to this pedal. Guess I'd have to open it up to see if anything has been altered. If it's not already modified, what modifications do you recommend, if any? I'm playing a Harley Benton Les Paul with Epiphone Probuckers through a 65 Amps London set at very mild breakup. Settings used on the demo for lead guitar. Settings used on the demo for rhythm guitar.
