I think I'm up to 7 now.
Let's see:
1. Russian Big Muff
2. SUF Green Russian Dlx - has a separate boost circuit that pumps up the volume and mids
3. Tone Hungry Fuzz Cream - Germanium Fuzz Face, love it, when the footswitch is working
4. Seeker Mk I - Killer Tone Bender
5. Warm Audio Foxy Tone Box - kinda Muffy with an octave, lovely box of noise, $100 used at GC right now
6. Wilson Effects Knuckle Dragger - Super Fuzz clone with tricks. Most bombastic of the collection, makes your guitar effing uge
7. BAT Pharaoh Supreme - Big Muff with tricks. Just picked up, haven't played yet.
8. Fulltone Soul Bender V2 - good Tone Bender III
I've flipped plenty, Analogman, Skreddy, SD, Pedalworx, Monsterpiece, Danelectro, Lumpy's, Colorsound...
The Tone Hungry is the most versatile for cleaning up, and then stacking for heavy stuff. One on Reverb for $110.
Tone Benders are my fav. MkI is just raw wall of sound, not much clean up, killer lead pedal. Mk III is more refined with good cleanup. I think Mk 1.5 is close to Fuzz Face circuit. Seeker, R2R and a few others are making some great fuzzes with NOS parts. Good used prices on Seeker at TGP. The Fulltone SB V2 is a good pedal, not much volume on tap, benefits from running into a cooking amp or a boost after.
The Warm Audio and Wilson Knuckle Dragger are big, musical walls of noise with octave capabilities. Much fun. The KD almost makes the guitar sound like a synth on some settings. Crazy.
The SUF pedals are fantastic, and a bargain at used prices, imo. The Astoria is supposedly a clone of one of Gilmour's Rams Heads. Muffs don't cut thru as well as the other fuzzes, don't clean up as well as other fuzzes, and benefit from something like an EQ, Timmy or Klon behind them to add a lil mids.
