Electro-HarmonixOp Amp Big Muff Pi Fuzz Pedal

Sounds great. It’s not picky about placement in signal chain.Love’s a Blues Driver, or a Tube Screamer before it. This will stay on the pedal board. Worth the money for a sturdy build quality pedal.

Love the classic sound. It won’t disappoint!!!

Amazing big muff! So good for shoegaze, post rock!!

As most of you who are thinking about buying this pedal already know, this is the pedal that was said to be used on the Smashing Pumpkins “Siamese Dream” album. It has that iconic, thick 90s fuzz tone that not only sounds like “Siamese Dream” but can also be tweaked to sound like most 90s bands that used fuzz like Bush, Collective Soul etc. It is also worth mentioning that the price is fairly cheap for a pedal of this caliber. It is heavy in weight so you know it is not cheaply made. Now I know that most of you notice that the price on Amazon is higher than most other music gear sites. While that is true, most of the other sites(at the time of this review) don’t have this pedal in stock and after paying shipping/taxes, you may end up paying 5-10 dollars(or the same amount)more on Amazon but they have it in stock and you get the pedal in a couple of days. I’m not recommending one or the other but do the cost benefit analysis for yourself. Lastly, if you hook up this pedal and immediately start playing “Cherub Rock” you will notice the tone sounds basically identical but something is off....what is it?!? According to my basic research, the band actually layered multiple guitar tracks in order to achieve the exact sound on the album. So what I’m saying is don’t get discouraged if your riff doesn’t sound JUST like the album because it is impossible unless you layer multiple guitar tracks. But this pedal gets you 95% the way there and that’s good enough for me.

I did not buy this to play smashing pumpkins, sorry, I bought it for the tone shape, it's awesome. I put it next to my EHX cockfight, they are definitely two different flavors. The cockfight has a percussive low end, downright mean sounding. The op amp is more a distortion with a nice spectrum, it will not be leaving the board. It is really a great pedal, get one.Update, this is my favorite pedal on the board, I have the revv g3, super badass distortion, cockfight, even my dark terror doesn't sound this good. My 85 peavey butcher pounds out tone with this in the low gain input, definitely ordering a backup.

Some people opine for the vintage version of this pedal, but I wanted something I could get now without breaking the bank. This pedal makes it easy to dial in those classic Pumpkins sounds, and it doesn't break the bank or take up too much space on my pedalboard. If you are on the fence between this one and trying to find a vintage one, look up the video where Billy Corgan discusses them both.

I got this and really liked the sound, but after a week it failed. Red light comes on but there's no signal, and yes I swapped in new batteries already. Called the manufacturers customer service but no answer. Bummer2/7/21 - Manufacturer customer service called me and said to get replacement through amazon2/14/21 - returned broken unit and ordered a second because this is such a great pdeal, they drop shipped it Fedex. so im giving this 4 stars2/24/21 replacement unit working well so far

If you're looking for great fuzz, look no further. Whether you're going for Black Sabbath or trying to nail that Siamese Dream sound, this is the one
