It’s like the pedal gods are listening to my prayers. Stop me if you think that you’ve heard this one before, but: I LOVE pedals that offer stacked drive tone! Bad Cat’s Siamese Drive has two overdrives in one enclosure. It’s not the only dual overdrive on the market, so what’s the twist?! Both overdrives are EXACTLY the same circuit. This means you can have two immediately recallable settings of OD or run one into the other for a third, delectable overdrive tone. I’m a big proponent of getting the most bang for both your buck AND your board real-estate. Once upon a time, I used two Boss Super Overdrives in this fashion—identical pedals right next to each other with different settings. The Siamese Drive takes this approach with one enclosure AND saves me a spot on my Pedal Power 2 Plus (though to be fair, it still takes up just as much space, if not more, than my two compact pedals did). Yeah yeah yeah, that’s what it IS but how does it sound?! It’s Bad Cat. It sounds awesome. The magic in this pedal for me is in not cranking it. It seems best paired with an amp that is on the verge of breakup (in my case, I used an AC15 and a Fender Excelsior) to really push the amp over the edge. Hmm. I don’t want to drop the K-word (Klon), but it might be somewhat applicable. Using the Siamese Drive as a clean boost (this can be done by turning the gain all the way down) or with just a touch of gain really helped push the AC15 into the perfect sweet spot and really brought the Excelsior alive. I found that for dirtier tones, I preferred a few of my other more obvious dirt pedals—but none of them have the finesse that the Siamese Drive has. Everything seems really solid on this unit, though my puny Black & Decker electric screwdriver did somehow manage to strip one of the Phillips screws on the bottom plate, so I was unable to look inside at the board. Bad Cat has a reputation that should inspire confidence about what’s under the hood, however. What we like: Three unique tones available on tap simultaneously. The cat eyes LED's are cool too. Concerns: None. Well, one. The aforementioned stripped screw; a tiny bummer that happens all too frequently to most manufacturers from time to time.
