Bob Sanders Signature Bass Trombone Mouthpiece – The Studio Powerhouse

Same rim and cup as our Chinook with a  considerably More Open Throat & Backbore. Bob Sanders a true giant in the Los Angeles studio world — a first-call bass trombonist for decades on blockbuster film scores, TV soundtracks, and recordings, while also teaching and mentoring the next generation with generosity and expertise. When Bob needed a mouthpiece that could handle the relentless demands of Hollywood sessions — massive projection, instant response, dark warmth, and total reliability — he turned to Giddings. This is the original Bob Sanders Signature — the piece that defined his sound in the studio trenches. It shares the same cup and rim as the Chinook (for that secure, comfortable feel and rich core tone), but we opened up the throat and backbore considerably to unleash explosive airflow, faster energy transfer, and a bigger, darker, mellower voice that fills the room without effort. Giddings uses harder stainless steel than the competition — a deliberate choice that gets your buzz into the instrument quicker, with less air and less work. The result? A seamless transition from player to horn, letting you forget about the equipment and focus purely on the art of music — exactly what Bob needed for one-take wonders and high-pressure sessions.

Bob Sanders' Own Words:
"The results are everything I wanted and more. Everyone I have played the Chinook  series mouthpiece for has felt there is more sound, sooner and a darker, mellower tone with abundant core and projection."
