Warburton P.E.T.E. Embouchure Trainer Si
This is just a must-have trainer for every brass player.
I use this almost every day in my car while driving to work. I admit, I get some strange looks when cars pass in a traffic jam, but I do not mind because this tool is helping me in getting a stronger enbouchure, more overall endurance and even a greater reach in my upper register.
This tool does not replace regular exercise, flexibility exercises and long notes, but it really helps me with time management.
I do not care a lot about all those different trainers, but this one always goed with me when I leave the house.
Thanks Thomann for the great service (as usual)
