Really wanted to test out a PRS low wattage amp at higher levels after hearing so much about how the MT-15 can stand up to a 50- or 100-watt amp. Don't have an MT-15, but running a PRS Archon 25 amp into an Emperor 4x12 cab equipped with Eminence Governors. Decibel Level measured with an iPad about 2 metres away. I think you'll find the results really fun! The volume is terrifying, as you'll see! I go from 7 o'clock on the amp to 3 o'clock! No studio trickery or wizardry! Audio recording using a Zoom microphone into my phone!
