| Flexibility wise there's no comparison, the VHT Sig:X is exponentially more flexible. Tonewise? That's definitely up to the individual's taste. I like Mark IVs, but I'm a huge VHT fan. I think they make the best amps in the world.
It really depends on specifically the kind of tone and response you're looking for. The Mark IV sounds great, but in terms of metal it's pretty much a one trick pony. It has 'a sound'. You either love it or you don't. The VHT is capable of many diverse tones, you can sculpt almost anything - in terms of both tone and the playability/response of the amp. |
