I just wanted to take a moment of your time to give a huge thumbs up to the amp lab! i reached out to them about the M7 set screw i was in need of and couldnt find locally nor on any of the sites i looked on (i.e. fastenal etc etc) and they replied asking me for my address, i gave it and they VERY promptly replied with a tracking number. I got it yesterday and it was EXACTLY what i needed! I asked them if i could pay them for it (the package said it cost them $2.85 to send to me) and they refused instead asking for me to spread the word about their kind act and prompt service. Big props to those dudes!!
