TBH, I've given up on any Youtube guitar demos, because 95% of the time, all I'm hearing is a. how good the guitarist is and b. their amp + Youtube's crappy audio compression.
A good demo can get me hyped about a guitar, but that's about it. If I buy a guitar, I am buying for ergonomics...
Marty will always be my favourite Megadeth guitarist, which is saying something because that band has always had top-quality lead guitarists the whole way, from Chris Poland and Jeff Young in the pre-Marty era through to Kiko Loureiro and Teemu (cannot remember how to spell his last name lol)...
I'm torn a bit. From the metal standpoint, it's a great name, particularly suited to the Lvciferion crowd. But yeah, it in no way conveys how versatile the pickup actually is. You can use it for all kinds of non-metal applications quite handily.
