I have decided I want to use my 40B as my main axe for rock and funk gigs. But the 3rd valve slide is too long and causes tuning problems. I think back in this era the 3rd slide was made long on purpose to help get the D and C# better in tune, even though it is a kicker slide. I have to push the horn above the center of pitch to get it in tune on notes that use the 2 and 3 combination, and using 3 as an alternate fingering is right out. Any ideas on how much I should cut? I figure I'll take a little off at a time and solder it back together and play it a bit and then take a little more off if necessary. I'll be making the 1st slide into a kicker as well.
