hAndSlideS
The prex “LT” before any Bach Stradivarius model number (such
as LT16M) indicates a lightweight handslide. Some musicians
prefer the feel and quick response of the lightweight slide. The
weight has been reduced by using nickel silver tubing for outer
slides. In addition to the light weight, nickel silver tubing also
resists corrosion. All Bach Stradivarius trombones not having an
“LT” prex feature regular weight slides made from brass tubing
for outer slides. All models can be special ordered with lightweight
nickel silver outer slides. Bach 42 series trombones can be
customized with narrow handslides for playing comfort.

Many Bach Stradivarius
trombones can be congured
with traditional, “T” Free Flowing
or Hagmann Valves. Bach
trombones with traditional rotor
valve sections offer a choice of
either open or traditional wrap.
Open wrapping of the rotor
section places fewer and larger
bends in the tubing, resulting in
less blowing resistance. Traditional
wrapping provides compactness
and protection. “T” Free Flowing
and Hagmann Valves systems
eliminate sharp crook tube bends
within the rotor itself. Combined
with open wrap section tubing, “T”
and Hagmann Valve systems allow
for a free and unimpeded ow
of the air column, regardless of
whether the B

of F sides of
the trombone are being used.
The top two pictures highlight
traditional rotor valves. Open
wrapping of the rotor section
(pictured top) places fewer
and larger bends in the tubing,
resulting in less blowing
resistance. Traditional wrapping
(pictured second from top)
offers the advantages of
compactness and protection.
The “T” Valve (pictured second
from bottom) and Hagmann
Valve (pictured bottom) allow
for a free and unimpeded ow
of the air column combined
with open wrapping.
