loudness

i bought a roll of the 3m sitkkit gold 320 at a place called cti abrasives in sanata ana. got a 45 yd roll for $29. stew mac sells a 15 yd roll for $40? maybe more.

i use the stew mac double sided nut files 12/16 24/32 36/42 50/60 covers most of my needs for acou and electrics i also have larger files for bass guitar nuts. 75, 90, 105 etc the xacto .010 saws are great for high e strings and starting slots

what typeof files would one use for workinhg on stainless steel frets? also what type of sandpaper. thanks

i watched that video clip and couldn't really tell what the frets themselves sounded like unplugged. each time he played the guitar it was plugged into an amp.
