Yeah - really good point that they didn't use the muff live. It might be worth watching one Billy's rig rundowns and copying that.If you want to try to mimic the record equipment, he did replace the stock JCM-800 tubes with KT88s, but I don't know what other changes resulting amp setting adjustments (bias settings? transformer settings?) you would have to do. Also, the Big Muff is the Op Amp version, which may not be the version in the Fractal. He was running the muff on full gain settings into a pretty clean head (KT88 doesn't overdrive as quickly as EL-34) and using the muff tone to find the exact spot where things turn a certain color.
On the other hand, the band didn't use the Big Muff Live, you lose definition trying to make that sound work in a really loud setting. You could follow Billy's lead there and consider using a higher gain amp. Last tip if you're interested, for the solo he's using tape flange, which the fractal has a model for. I messed with starting a patch for SD songs but I haven't really finished. Also need a phaser set to really slow rate to get a lot of the lead sounds.
Note that you can set the Muff to Op Amp. I haven't noticed a difference, but my preset uses that (and KT88s in the amp) just for "accuracy"
