This is THE Big muff!  What a clean machine!  A local customer found this at a recent yard sale - amazing!  He has his first baby on the way, so handing him some solid cash for this felt good!

Electro-Harmonix founder Mike Matthews recollected in 2007: "Back in 1969 I was already selling the Muff Fuzz, which was a mild overdrive circuit in an LPB-1 box. I wanted to come out with a three-knob distortion unit in a bigger box. I asked my buddy, Bell Labs designer Bob Myer, to design a unit — one that would have a lot of sustain. When I got the prototype from Bob, I loved the long sustain." Mike hand-wired the first run himself, including one for Jimi Hendrix. The guitar effects pedal that would define more recordings, inspire more circuits, and influence more players than any other distortion or fuzz device in history began in a New York City apartment with a Bell Labs engineer and a request for sustain.

The earliest V1 Triangle Big Muff, introduced in 1969, features a crude design with simple black font and very little in the way of ornamentation — the three control knobs forming a triangle in their layout, which is how the first generation came to be known as the Triangle Muff. The on/off switch configuration — a toggle switch rather than a footswitch — identifies this as one of the earliest examples produced, before the design evolved to the footswitch bypass that later versions adopted. The all-metal finish casing with simple black lettering and knobs in a triangle formation represents the earliest and most valuable model. 

The characteristic properties of the Triangle sound are smooth highs, warm bass, and comparatively low gain — even with the sustain all the way up, the classic Muff violin sustain leaps from the speakers, and with sustain down the Triangle functions better as a low-gain drive than later Muff variants, which only really sound good wide open. This is the specific voicing that David Gilmour and Carlos Santana used earliest, before the Ram's Head and later variants shifted the character of the circuit. Early Big Muffs were purchased and used by Jimi Hendrix, Carlos Santana, John Lennon, Robert Fripp, and Steve Howe. 

Near mint condition.   A pedal from the first three years of production that Mike Matthews hand-wired himself in the first run. The reissue EHX released in 2018 for the company's 50th anniversary confirmed that original Triangle examples were by then selling for hundreds of dollars and that the circuit remained definitive enough to warrant exact reproduction. This is the original. There is no substitute.

Great for potty training
Size: 3T-4T, Unit Count: 20
We really like these pull ups and they have worked well for us during potty training. They are easy to pull on and off, which is great for toddlers who are learning to be more independent. They fit well and do a good job containing messes without leaking. I also like that they feel comfortable and not too bulky, so my child can move around easily. Overall, these have been a reliable option for us and something we continue to use during this stage.

Nice
Size: 3T-4T, Unit Count: 112
Good pull ups, it could get a little linty but it fits perfectly on my toddler. It stretches which I love. I do love how I could strap and unstrap the sides of the pull up. The designs on the pull up are cute. It holds a lot of pee and soaks it up very well. It’s comfortable on my toddler and the pee and poop doesn’t leak out of it. It is worth the money.

The Fast & the Curious- Potty Drift
Size: 5T-6T, Unit Count: 60
Who knew toddler potty training required both a PhD in fluid dynamics and Jedi mind tricks? These Pull-Ups prove the science part: leak-proof, absorbent, and surprisingly soft. The toddler-psychology part? That’s a battle of wills. Our little one was a die-hard fan of Huggies diapers—too loyal, in fact. We begged, we bribed, we pleaded: “Please, let’s move on!” Resistance was fierce. So we went stealth mode, sneaking Pull-Ups on at night like parents on a covert mission. Credit to mom—she cracked the code and finally got the kid interested in the toilet. Suddenly, the “potty rush” moments became less of a flood and more of a sprint. Diapers were too slow to peel off; Pull-Ups gave our little sprinter the speed boost they needed. They’re soft, rash-free, and practically leak-proof (unlike that other brand we don’t speak of). Pro tip: size up for easier toddler self-removal. The result? A drier, happier kid, less laundry for us, and the toilet finally earning MVP status. If you’re ready for your toddler to graduate from Diaper University, this is the diploma. Bonus: you’ll save money too.

Mom of 3 recommend!
Size: 5T-6T, Unit Count: 14
I'm using these again for the 3rd time and they're great as always. My 3rd is still having some issues at night time with bed wetting, and as they get older the bigger the mess, so these truly hold up to a full bladder. And they don't smell by morning like some diaper brands. I'm usually against pull ups, but these are great for up and down ease of use and that added protection when it comes to potty training. I love the bigger size inclusion for larger children which we struggle with for comfort compared to other brands.
