I haven't seen a source explaining which Big Muff was used. Comparing a Triangle, Purple Ram's Head and Civil War, the Triangle Big Muff sounded closest. In terms of what could be commonly available, the first version of the Ram's Head which had the same internal components is probably accurate.more
In an interview with Phil Taylor, David's guitar technician. He is quoted in the article as saying : "PT: It think it's just pretty much him. He is obviously using a couple of effects, like a Big Muff and a delay, but it really is just his fingers, his vibrato, his choice of notes and how he sets his effects." David Gilmour has been known to use the Big Muff on one of the most renowned guitar solos of all time, the solo from Comfortably Numb.more
At 9:58 in this video interview, J Mascis talks about his Big Muff Pi Pedal, saying, “I got it in '87 on our first tour. Before that, I was using a Deluxe Big Muff and then I got that on tour and then I started using both of them, but I really like that one. From then on, I just used that.” He provides more detail at 10:34 saying, “It seems a bit clearer. It's really easy to play rhythm. That’s my main distortion for rhythm sounds and lead. Some Big Muffs kind of get really mushy when you're playing rhythm, it's hard to articulate the notes. That’s the main thing I notice about it.” The Big Muff is demonstrated by J at 21:34.more
Sound varies between fuzzy/sludgy and edgy. It's very good for stoner rock/metal. When a friend plugged in his ukelele it sounded very nice, you could play punk with an ukelele.
big muff fans do NOT get excited and start asking me to sell you this.... I've had this forever and its super-broken. If I did fix it, it would not be original. All the transistors are shot. It looks like a previous owner immersed it in a swimming pool. Big muffs are pretty overrated anyway and one sounds much like another. I'll bet some dude got sick of the mid scoop and flushed it down the toilet. I really intended to fix this up back when iw as into muffs but a friend of mine has a very similar ram's ehad that works and I was really underwhelmed by it and I pretty much then switched over to tonebenders and rats then.
