What happened to EHX? Nirvana fan club? This is usable chorus for different type of sound (blues, hard rock, classic rock, pop, jazz, metal, extreme metal) which I tried.
I've tested it on:
Gibson Les Paul Faded 2018
Fender Stratocater Deluxe
Marshall DSL40CR
Marshal MG10
Pros:
Great sound
Nice design
Strong box
Analog sound
3 command only - easy to handle and experimentation
Cons:
For God sake, don't put Nirvana everywhere. Yes, you can easily make Nirvana sound, but you can make manyu different sounds, so please stop advertize this effect with Nirvana. I opened package and found "your Nirvana@. I like Nirvana, I listen Nirvana almost every day, but I haven't buy Electro Harmonix Op-Amp Big Muff Pi Fuzz (valve based and great fuzz) only because it fits good for Nirvana only and similar bends. Think about it!
