Hey guys,

I'm wanting to buy a trombone and I found an offer for a Couesnon Monopole trombone, but I don't find any source of information on these.

I've seen a video of a guy playing a Couesnon Monopole trombone on youtube and I found it has a great sound (<YOUTUBE id="g20_wL1CLJ4">https://youtu.be/g20_wL1CLJ4?si=rjnQ20D5PeJv32BS),</YOUTUBE> but it's not the same shape as the one i've seen :



Do you have any idea if it's worth it or not ? (I can't go and try it the seller is quite far from my place)

Best,

Bever
