share your dirt pedals here (no boosts unless the can produce their own dirt into a bone clean amp).... I am going to split my list up into good and bad (for my tastes), maybe everyone else do the same and we can get discussing. This is a sensitive topic and one man's trash is another man's treasure so be nice, no flaming. All tones can be legitimate in the right context.
Good: DOD OD250 and 1st gen Distortion FX55 (very similar, classic bare bones diode to ground OD, hard to improve on, better dynamics than DS1 and no tone control to fuck your EQ response up), Ibanez TS9 original issue (classic, awesome with Fender amps, hard to improve on, given to a friend for xmas), Boss SD1 original issue (Boss's version of the TS9 with assymetrical clipping diodes, crunchier top, different mid emphasis, similar bass response), Proco Rat 80s, Colorsound Overdrive (a boost, an EQ, an OD, a fuzz, trashy, transistory and pure rock), Boss OS2 Overdrive/Distortion (meaner than an SD1, better voiced than a DS1), MJM Brit Bender Mk3, Univox Superfuzz, custom low gain silicon fuzzface clone, EHX muff fuzz, V8V sweet 'lil '66 tonebender 1.5 clone, mid 60s Vox Tonebender, BYOC Tonebender professional MK2, Burns Buzzaround, Stomp Underfoot Skreddy Mayo clone, Way Huge Red Llama 90s (based on Anderton's tube sound fuzz project using CMOS inverter chip, awesome tweed type sound, great dynamics and bandwidth, a little noisey), MXR Super Badass modified Overdrive (an SD1 with the option of flat or humped mids, a better tone control and a bass gyrator that boosts or cuts 100hz after clipping, easy to tailor to your amp's voicing and to sit well in the mix of your band, a green rhino mk2 with asymmetrical clipping and less mid sculpting), EHX Soul Food (Klon clone, gets close enough for most people including me.... needs a way to bring the bass up for some amps and applications after clipping when used as a dirt machine and not a clean boost, otherwise awesome... fairly transparent, could be more dynamic, I have thoughts on improving the circuit, I might make my own modified Klon soon)
Bad: Ibanez TS5 (sounds like a TS9 for cheap but the plastic tac switch breaks easily), DOD FX55b Supra distortion (awesomely buzzsawy, 90s tones, I actually kinda miss her awful sounds), EHX Russian big muffs Green and 1st gen Black (very similar, both boomy, fun on bass), Ibanez Sonic Distortion SD9 (reminds me of the DOD FX55 but not voiced to my taste, might suit a lot of other people though), Marshall Bluesbreaker silver box 2nd gen (meh, black box 80s ones are supposedly better, whatever, not for me, too bland), MXR distortion+ (like a gainier, less dynamic OD250), Sans Amp 1st gen, DOD YJM250 (brighter, crappier sounding OD250), MXR Distortion II (unique sound, but not particularly useful), Jack Oram Fet Muff (surprisingly abrasive for a FET based design -- not like anything else I've heard but not terribly special either), GGG BSIAB2 (cranked marshall tones from 2 cascaded Oram miniboosters, awful tone control, sounds transistory and almost like a fuzz at high gain settings, basis of many marshall in a box pedals), Boss DS1 (the distortion we all love to hate), 70s EHX Ram's Head Big Muff (big let down), 90s USA Big Muff, BYOC Large Beaver 1st generation with 'triangle muff' specs, Fulltone Fulldrive mosfet (somewhere between a TS9 and SD1, very expensive without much in the way of additional tone shaping, I'll stick with the original Ibanez and Boss units or better still the useful features on the Way Huge and MXR versions), 90s Vox Tonebender RI (small black box, not as good as original in any way, great mod platform), Skreddy Pig Mine (another tweaked muff, supposed to get the David Gilmour Muff sound, fails, more of an unmuffy muff sound LOL, preferred the Mayo circuit, the best Muff style I have ever used but muffs are still overrated), Carl Martin Plexitone (part of a cash plus trade deal for my last ACTUAL Marshall plexi, suffice to say it does not have a plexi tone but did have good resale), Carl Martin Crunch Drive (sounds a lot like Marshall's bluesbreaker pedal with more gain and less dynamics, part of the plexi trade, sold, bad resale), Barber Direct Drive (part of plexi trade, british flavored OD, nothing special, good resale), Catalinbread Hyperpak (great tones in the red llama camp but hissy even at low drive settings, lent to asshole friend of ex-wife, never returned), Mosrite Fuzzrite (great for Iron Butterfly covers and little else), Shine-ei Companion fuzz (make your guitar sound like a musical chainsaw, funny, valuable, sold), MI Audio Crunch Box (popular marshall in a box, sounds a lot like the Marshall bluesbreaker pedal), Xotic BB preamp (not a bad juiced up ts9, but the 2 band tonestack is tuned in such a way that it changes the EQ of your clean guitar tone way too much at ever possible setting), Maestro FZ1, FZ1a and FZ3 (too finicky, only useable for recording retro material, piss weak output, very gimmicky, best to borrow if needed), Blue Silicon BC108 Fuzzface 70s (spitty, harsh, velcroey, fun but too valuable to keep, very gimmicky), BYOC ESV germanium ac128 fuzzface (just meh), Sam Ash fuzz box (okay with humbuckers, awful with fender pickups, not enough output), ZVex Distortron (almost perfect yet not right for me AT ALL, getting so close to a great cranked amp tone is worse than not sounding amp-like at all, but she's good for someone though... very similar in design and tone to BSIAB2 except using mosfet based SHO boosters in series with the big muff inspired tone control instead of 2 dual jfet mini-bosters, different tone and feel, tubier than BSIAB2 but also not as good for heavier music, bass contour switch is handy, tone control STILL holds her back ).
I think that's all the dirt boxes I owned and used for any period of time. Chime in. I know there have been similar thread, but not tackled comprehensively. WHat are your winners and losers?
