How is the TromboneSpineSaver™ Performance Stand different from Ergo-Bone or Ergo-Brass?

Weighs 29 oz     Weighs less than 14 oz.
Takes about one-and-one-half
minutes to put on the vest, attach
the main clamp  and
adjust it to playing position
Attaches to the trombone in under
ten seconds.  Adjusts to playing angle
in four to six seconds
Performance angle changes as
the player inhales and blows with
the vest attachment
Performance angle changes only when
readjusted because it rests on the chair
or on the belt clip attachment
Takes about twenty seconds to
change from vest attachment to
seat-length pole - - and I am still
wearing the vest.  A piece has to
be added to achieve seated length
Takes four seconds to go either from
standing to seated or seated to standing.
The belt clip attachment is already in place
and does not need to be removed or
attached to go from  standing to sitting.
Main clamp slips, no matter how
tightly I secured the fastener screw.
The posterior/anterior angle suffers
the most for consistent positioning.
Does not rely nearly as much on clamping
force to hold the adjustment so, once
adjusted, it does not slip.
Relies on the left hand to prevent the
main clamp from slipping.
Vertical weight is securely cradled and the
lateral and posterior/anterior adjustments
are independent so they bear far less weight
of the instrument and are, therefore, more
secure.  Nothing is required of the left hand
to maintain lateral and posterior/anterior
Takes about thirty to forty seconds
to remove the vest and the clamp
for storage.
Detaches from the trombone in about four seconds
Has all connective stress on the
trombone focused in one location,
making it prone to wear and slippage
as leverage works against its proper
functioning component part.
Distributes the weight and imbalances of the
trombone over three points of connection.
Each connection uses leverage to its
advantage to reduce wear on each
Is visually prominent, draws attention to the fact that the player is using a stand attachment
Is visually subtle, drawing less attention to
the fact of it being used - - unless one chooses bright-colored straps. Also has a more aesthetic appearance - - less bulky; customizing options.
Main clamp may remain attached to
the trombone (although I did not find
this to be an advantage because I had
to disassemble it again when re-attaching
it to the main stem for use)
The only requirement for any part to remain
attached to the instrument during storage is a silcon tube stay
Vest attachment puts the weight of the
trombone on the upper torso - - the
respiration center of the body
Belt clip attachment puts the weight on the hips
when standing.  There is no upper torso involvement
in supporting the trombone

What I like most about TromboneSpineSaver™ Performance Stand is:

  1. That I don’t have to wear a harness to stand up and play - - just a normal belt with a clip receiver, so it doesn’t touch my body any more than a normal belt.
  2. The trombone is securely cradled in three places rather than forcefully clamped in one  - - less physical stress on the instrument
  3. Quick-release set screw knobs allow quick and accurate angle changes in six directions that do not slip because they use leverage rather than fight it.
  4. There is nothing to fall apart when removing it, whereas the main clamp of ErgoBone tends to fall apart into three pieces when I take it off of the trombone or reattach the main stem.  I can see kids complaining that they lost this or that part of the main clamp when they were in a hurry to detach it and get to their next class.
