Okay so I was in the market today looking for a new overdrive to see what my options were and I saw a Boss SD-1 for 30 dollars. I figured, ah what the hell? If I don't like it, I can always get another TS-9. So I traded my TS-9 for it, plugged it into my amp and holy shit... Grime and grind like you wouldn't believe. Keep in mind, I'm running it into a 6505+ with a 2x12 with Governor/Swamp Thang combo. It doesn't have the annoying mid hump that most tube screamers are known for. Just a clear hard edge with no squishiness or anything like that. I don't have pics and I don't have the capability to post clips, but needless to say, this thing is doing the job I WISH my TS-9 had been doing all along. For what I play (black/thrash/death metal) this thing absolutely slays. I understand it's got less than stellar views in some places, but for me, this thing is perfect. I'm also proud to say that I actually came up the better end of the deal seeing as they gave me 17 dollars back. Worth it? Not sure. But that 17 dollars is going toward a fret dress on my Epiphone and the same Epiphone is being set up in B standard for some good ol' At The Gates style grime. The first thing I noticed however was that I needed a tad more gain on either the pedal or the amp to give me the same juice that a boost normally does, but it made my amp go from sounding like the typical metalcore amp to an all out hate machine. The only thing I can't wait for is to see how my Epiphone with Black Winters sounds in B standard through it.
