Hey guys,

I'm going into college and my trombone playing days are unfortunately coming to an end. I'm looking to possibly sell my Stradivarius which i bought a few years back, but i am having trombone determining the exact model of it. I know it is a model 42, and it is convertible with an open wrap. That leads me to believe it is a 42CO, however all the pictures of that model online do not show the circular piece at the top with the Bach inscription on it. I'm posting a link to my Flickr account and i have a few pictures of the bone there. If someone could tell me the model of this Stradivarius I would GREATLY appreciate it. Also, anyone have any ideas of what i could fetch for this? Thanks, Kevin.

Bach 42CO. But it looks like you have two leadpipes, right?

The circle is a counter-wight that is supposed to be used with the straight horn and not with the F attachment, that's why the pics you see don't show the counterweight. If you look at any standard pea-shooter or pro-level straight tenor, they almost always have a counter-weight.

$1500 if it's in great shape, just because it's convertible. But $1200 is a fairly safer estimate for a horn in decent shape. Sell it on Ebay.

Yeah I have two. One has a "O" marked on it and is significantly longer. I believe there was 3 when i got the trombone but i cannot locate it. To be honest, i'm not too sure what these even do. Do they come standard with the 42CO?

The leadpipes change how the air enters into the horn, making it easier for example, for upper-register (lead playing) so one such as that would be best used for the straight horn for Jazz, etc. I don't know too much about the Bach line of trombones, so I don't know what any of the markings or numbers mean. Is there a .547 or .525 marked on the lead pipes. they may even have like a 1 or 37 or something like that also. I can do some research and get all the specs so when you do sell it, you can be a well-informed "salesman." However, without having the thing in front of me, I have nothing to reference to.

Heres what I found one one of hits from a google search for "bach trombone leadpipes." The info is from Hickeys Music Center. But it done/t mention the standard bach markings just Hickeys model numbers. The 3rd pipe you are missing is probably currently in the trombone, by the way.

INFO:
Removeable Leadpipes, Set of 3

Available on 42 series tenors and 50 series basses. Each leadpipe in the set is tailored for a different performance characteristic. The leadpipes included in the set are, for the 42 series tenors, a V42S, V42SO and V42LO. For bass trombones, the models include V50S, V50XO, and V50XX. (These model numbers are Hickey's own. Each leadpipe is described below.) The shape of the leadpipe has a great deal to do with the way the instrument performs, indeed many would say it has everything to do with the character of the horn. Being able to change the pipe is a fast way to alter the fundamental playing characteristics of the instrument without the need for a gas torch, flux and solder. For most artists, the intent of a triple set of leadpipes is not that they will be changed often or depending on the situation. Instead, usually one pipe is chosen from the set as the one best suited to the artist's physique and performance style, after an extended trial period. That leadpipe often becomes the "default" pipe with the others placed in storage for occassional use. Your mileage may vary, blah, blah, blah.

V42S - standard pipe for the 42 series tenors.

V42SO - standard length pipe with more open venturi (wider diameter at the "pinch") for less resistance and more flexibility.

V42LO - long length with open venturi, for a very free-blowing instrument.

V50S - standard leadpipe for 50 series basses.

V50XO - short length, open venturi for less resistance and more flexibility.

V50XX - no venturi tube, mouthpiece receiver only, for playing on a "leadpipeless" horn that's very free blowing with little focus.
