If you haven’t heard of either the Kemper Profiling Amp or Andy Sneap then you have clearly been living under a large naturally occurring solid aggregate of minerals and/or mineraloids, in which case just watch the video above for an explanation of both! The Kemper Profiling Amp is really gaining a lot of respect with guitarists and producers/engineers and it seems perfectly suited for Metal as demonstrated above.
