Boosted 800 through a pro rack, back in the 80's. It was like the voice of God.
A buddy's Diezel Herbert. I had never heard anything like it in my life, and knew I had to have on immediately; that's how I found Rig-Talk.
Mark's stuff has absolutely floored me on multiple occasions, but the biggest WTF moment was an amp he called the Custom 75.
The Custom 75 was laying in a corner of his house, with a makeshift face plate, and spider webs inside.
He says to me, "hey dude, take this and check it out; let me know what you think"
It was a Friday night, and I was going out, so I didn't plug it in until late the next day....in all my years of playing, that was probably my biggest single holy shit moment....absolutely blew me away....mostly because this unfuckingbelievable amp was just laying in a corner, with no real plans to see the light of day.
I posted up clips of that thing back in the day...wish I still had them....
Jaw dropper, for sure.
