ToKo Klangbogen made of brass, for a better saxophone sound. Creates a much stronger and fuller sound across the complete spectrum. The Klangbogen is fixed to the support used for a marching note stand. Due to the differing mechanic arrangements on each instrument, you are able to fix the Klangbogen in 3 positions to avoid contact with them.
Sceptical prior to purchase. Not after buying it! Definitely gives a bit of a richer tone. Can't say it's dramatic, but definitely a noticeable improvement. For the price, that's an absolute bargain. No instructions in the box so loses a star :-)
