I have 2 Bach 12`s a Lt12G with a Kanstul W^ leadpipe has been my Daily horn for years

About 4 years ago I bought a 1965 12 with a standard weight slide and yellow Brass bell.

It played great but was a little front heavy.

I decided that I was going to modify the slide. 1st I hunted down a nickel light weight 12 hand slide crook.

Bach had none. Nobody had one except...... Brad Close at the Brass Medic Thank you so much!

I took it to a local repair tech to have the outer slide sleeves removes and the Nickel crook put on.

If you are on the Gulf Coast of Florida, Andrew Beecher is Fantastic.

I love the lighter slide on the horn. Glad I had it done.

Picked it up Sunday am. Had a Jazz quintet gig that day, 3 on Monday , 2 Tuesday , one on Thursday and a Big band gig Friday and the horn has Shined every time!!

Carl Fontana had exactly that.

That's a lot of gigs

I love my standard mid 70s Bach 12.
