Pros: Compensating 4-valve (3+1) with one-piece bell construction

The Yamaha 641S (YEP-641S) is the predecessor of the 642 and 842 models. It is a 4-valve (3+1) compensator with monel valves and hard plastic valve guides. It has a warm tone -- darker than most Besson compensator's. The 641 has a bore of .591 / .661 and has a large mpc receiver. Many feel the 'one-piece' bell construction is a plus over the 642 - which replaced the 641 (I know that I can't break up the sound by trying to over blow it). I do think however, that the 642 has a better response in the low register (peddle notes). Intonation is excellent - but I do use 2-3 fingering for the high concert Bb. I use a Doug Elliott mpc with this horn (LT-102 rim, LT-H cup, H8 shank).

If you're interested in purchasing a YEP-641, you'll have to find one in the used market as this model is no longer made.

Pros: M/L bore. compensating

Bought it 15 years ago. Loved it then @ still love it.
Easier to blow than most other euphs i've played.
Found the plating wore off pretty quick. It could just be mine.
