Common Questions About the S.E. Shires 'The Monster'
What sound concept does the S.E. Shires 'The Monster' pursue?
The S.E. Shires 'The Monster' is built around a huge, dark bass trombone sound with a broad core and strong projection. It is intended for players who want substantial tonal depth while maintaining control in demanding musical settings.
How does the Bollinger dual-bore slide shape the playing experience?
The .562/.578 bore Bollinger bass trombone slide supports a broad, open feel while retaining definition through articulated passages. The tone intensifier further supports the instrument's large, centered sound concept.
Why use a nickel silver tuning slide on this build?
The nickel silver TN tuning slide gives the instrument added immediacy of attack and articulation. On this build, that helps balance the darkness of the red brass 10 inch bell with a more direct front to the sound.
