Anyone here tried one of these? Found a used one at a local music store for a decent price. It's super lightweight because of the newfangled magnet it uses. I'm trying it out in my Peavey C30. It sounds a bit better than the stock Blue Marvel (to me). More bass and defined highs. More pleasing midrange. Not a major change, but it definitely sounds warmer to my ears and seems to tame the lead channels squishyness at higher gain, a bit. This one is the 100W/16ohm version.
