The Bach 42 Thread

[CSO4ever]

I’ve been playing Bach trombones since high school, and I believe it will stay that way for the rest of my musical career. Currently, I play the LT42AFG model, where I replaced the nickel on the slide crook with brass. The slide is very fast, and with this change, I’ve also slightly darkened the sound, bringing it closer to the characteristics of a regular brass slide. I like Bach trombones because of their full and distinctive tone, and the instruments offer a wide range of color that can blend into various ensembles. Over the years, I’ve played many excellent Bach trombones from different periods, each with its unique sound, naturally at Bach’s high standard. The only downside to Bach trombones (and, of course, other brands) is the poor quality of the lacquer, but due to the phenomenal sound, this doesn’t bother me.

I own and play a Bach 42G with a 3 piece interchangeable thayer, straight pipe and traditional rotor. Does anyone know the subcaprion on this model?

42G..TO....???

There should be C (convertible).
Maybe something like 42CBOT or 42COBT?

I have a 36 with F-attachment, straight pipe, gold brass bell, and lightweight slide. It is LT36CG. For rzeilinger, I would guess 42CT.

He has 2 valves (rotor and Thayer), so, CBT or CBOT (for closed or open wrap).
By the way, I'm curious, was it factory special order and what case accommodates all of these pieces.

[Kevbach33]

All axial flow valve (Thayer included) sections need to be modular to allow removal for servicing. There's no sane way to build it as a fixed section.

My guess is it either started life as a 42C(O) and had an aftermarket Thayer valve section added, or (less likely) as a 42T with added neck pipe and rotor sections.

[hornbuilder]

When axial valves first started being installed on instruments, they were "hard mounted". The front bell brace was solid, with the handslide receiver, valve cone/casing and top valve wrap tube all permanently attached to the bell.

The only one that is a factory is the artisan line… I don’t know that they bother to stack up the alphabet soup on them like the ‘standard’ 42s.

If it is an aftermarket Frankenbone, name it whatever you want.

Like how I have a 42 CO,T,K,CL2000,CR,&Monster. How I answer what it is depends on which pieces I have with me and then explain how I got there… Ship of Theseus history, if you will.

Considering that my 42 started out as a 42CO with an extra bell and 2 extra leadpipes, and has gone through multiple versions over the last 35 years with stuff added, subtracted, and replaced, I call mine a 42.

Sometimes I call it Betsy, but it doesn’t answer to that.

[sdenlinger]

For those of you who have played older closed wrap 42s with the original valve, as well as the open flow valve on the 42BOF, how do they compare? I really love the sound I get from the mid-70s 42 with the stock valve I'm currently playing, but is the open flow valve substantially different? Different throw? Different response?

[Burgerbob]

Way different. The open flow is a much better rotor than the stock rotor.
