This pedal is an amazing deal! I have always been into big muffs but the original design and variants are not always very responsive when you're dialing in your tone.
What I love about this pedal is that you get the classic NYC Muff sound if you only use the 3 classic knobs in the normal mode.
For added versitility, the bass boost function really gives my single coils depth.
The attack really helps bringing clarity into chordal work. I also use fuzz pedals while playing some chords or filling certain passages and with a regular Big Muff, there would be no note clarity for more complex chords. Not with this unit, chords are much clearer with the attack knob maxed.
Due to the nature ofbig muffs, they are really noisey. With the added gate knob, this is no longer a problem. It is extremely sensitive and I usually use it before 3 o'clock. If I want really prominent staccatofuzz sound, I just pump up the gate knob and get really gated fuzz sounds.
Another inovative feature I really like to use is the Mids part of this pedal. I have at least three ways I like to use it: As a normal mid boost, as a clarity enhancer or as a dramatic effect. You can really sweep through those mid frequencies and dial just the right amount.
If used with an expression pedal, it yelds some some frequency sweeping sounds just like a wah would. I usually set it and leave it but you can change it on the fly should you wish.
I woudn't change anything to this pedal. It's clear, noise free, fairly priced , has a low current draw and is realiable and durable.Amazing sound and quality we have come to expect from Electro Harmonix.
