Yanagisawa BWO20 Baritone Saxophone - Bronze


Top-of-the-range Elite Yanagisawa made from solid bronze - Saxophone engineering doesn't get any better than this!

The WO series for baritone is here! Yanagisawa have refreshed their range and made improvements to their already highly regarded baritones. The BWO20 is their top-level bronze model and it brings us some adjustments in intonation and further advances in key mechanism and layout. The best has just got better!!


The Yanagisawa BWO20 baritone saxophone is the real deal when it comes to top-notch baritone saxophones. With its bronze body, it brings a warm, rich tone that sounds huge. Smooth and easy to play, it hits all the right notes every time. Whether you're rocking out with jazz, keeping it classic, or exploring new sounds, the BWO20 has your back with its killer sound and rock-solid reliability. This saxophone means serious business.

The BWO20 is considered one of Yanagisawa’s ‘Elite’ models, and in practicality, this means that there are some refinements in mechanism beyond what is available through the BWO1 and 2 models. Firstly, the BWO20 includes a ‘fully ribbed’ construction – this means that there are strips of brass soldered onto the body of the sax, on to which the various pillars are then soft-soldered themselves. This gives added ‘body’ to the tone while offering even further solidarity of design. Secondly, the Elite series offers double arms on the lowest and most vulnerable keys, again adding stability to the setup.

Staff Review

Could this be the best modern baritone in the world?! The bronze fully ribbed construction gives off the most exquisite and pleasing sound imaginable. Okay, it’s true, I’m not a baritone player, but if you pick this beast up and give it some stick, everything becomes easy! I think that Yanagisawa’s attention to detail when it comes to improving something that has been considered an industry-leading baritone for years is admirable. I find their entire WO series of baritones an absolute joy to play – the sound is the most responsive of all baritones I’ve ever tried; playing down through to the lowest register feels like an effortless process, and mechanically it is a dream! You can’t ask for more. Jim - SAX


WO Baritone Features

Let’s take a look at the improvements that Yanagisawa has made with regard to key mechanisms.

1. Change to the angle of the right little finger keys for smoother fingering.

2. Set of ‘feet’ underneath the side Bb & C levers – plus an optimisation in the mechanical side of producing these notes.

3. Newly designed Low A thumb key for smoother fingering.

4. Repositioning of the strap ring for easier playing.

5. Newly designed right-hand key guard exclusive to the new baritones. This protects the player from getting their trousers caught in the mechanics, when balancing the bell section on this area!

6. Redesigned upper bow brace for a stylish look!

Secondly, there are adjustments to sound and intonation:

1. Readjustment of tone-holes sizes and positions for better intonation.

2. Addition of a plate on the front of the neck pipe for a ‘tightening of the sound from middle to high register’.

3. Newly sourced Brass material for WO1 and WO10 

And finally, there is a newly designed case, offering much more practicality over the previous model. In-line with the altos and tenors, it is now a back-pack style design! However, for baritone they have included some beautifully designed and slickly inset wheels, essential for any baritone player out on the road! This case also has much more pocket space to store one’s accessories.
