THD HOTPLATE 8 OHMS ATTENUATOR and BRUEL & KJAER 2250 SOUND LEVEL METER test demo slm spl dB

Demo of the THD hotplate with a Bruel & Kjaer 2250 Sound level meter. I stood outside the room to try and minimise the string noise being picked up by the very sensitive sound level meter and the mic. if you're planning on getting one of these with the intention of cranking your amps volume and then squashing it down to whisper/bedroom levels...be prepared to be SEVERELY dissapointed,(the fizz you hear is in part to the speakers not being able to move efficient amount of air.) but used sparingly (ie -4db to -8db) this can be a very useful tool to get your amp closer to that "Sweet" spot. also...believe it or not...in my 15+ years of guitar playing, this was the very first time ive played these AC/DC chords!!! (so its prob wrong in the transitions)
