*The original Ullvén "Copper CUP Mute" Chrome plated.
(Tenor Trombone small Bell).
 
# the original Ullvén popy Cup mute with an adjustable cup will coverall you need.
# Can be all from a tight cup soft warm, to an open bright crispy sound, rich in overtones and perfect in pitch.
# the Cup can be used as a plunger and without the cup, the torpedo/Straight part becomes a nice ”Straight” mute.
# with this mute the brass player may cover 90% of the requi- rerments and it gives the solooist a greater spacesound.
#put a sock in the cup and use it tight, you will have a great practice mute.
 
#The Chrome Plating gives the mute a little more brighter sound and great projection. It also stays shiny and if needed, easy to polish with some metal polish cream.
 
*Note, The Copper metal give the mutes more weight compared to Aluminium.

they are clearly the best mutes that can be found
in today’s situation !! output solid warm sound, no
one else has it !! have played a lot on the old ”wah- wow”
bop mute (Dizzy gillespie original) now, and, 
fantastically good when the Cork is sharpened!!

I love the tenor cup you made! I play it all the time. I'll play it tonight actually on my gig It has this beautiful vintage quality to it, where you can get the cup mute timbre & sound like JJ Johnson or Frank Rosolino.
