I think our tastes in pedals is pretty similar!Fulltone Octafuzz-The fuzz so good you want to make it work in any context even if the nature of the pedal doesn't suit what you usually go for. Use it as a boost for any other drive or fuzz for great results.
Earthbound Audio Supercollider 71-I love Muffs and this is the best of the many I've used so far. The perfect balance of fatness and high end with the added mid-range boost just sounds incredible. It instantly blew my band mates away the first time I used it.
Boss BD-2W-I've been through a good many ODs from cheap as hell to expensive as hell and I definitely like this one the best. It's very transparent and just adds a little bite and volume how I set it. Honestly I pretty much only use the stock mode so I assume this could apply to the standard BD-2 as well but I've never actually tried a regular model.
Blakemore Deus Ex Machina-OP Amp Muff with mid boost and clean blend. If you're like me and really dig that Siamese Dream sound but don't want to get lost in the mix this pedal is the one for you. I don't mess with the clean blend but smarter minds could make that work in cool ways.
Edit: Nevermind. Going in for #5!
Catalinbread Perseus-Okay so the Perseus is ****ing insane. It's like bridging the space time continuum from now to the 70's using LSD to create thundering computer riffs. Tracking is great, tone is great. Add a phaser or chorus to add movement to your epic sustain or play quick syncopated riffs and blow people away. Also you can use it as a regular old gated fuzz. What's not to like?
