Charlie is a great trumpeter, and a very handy fellow. He vented the valves on my PT6p and replaced a valve cap "pearl" with "my overscale." He threw in a great valve alignment to boot.

If you're not familiar with Charlie he is former Principal Trumpet with the Israel Philharmonic and Seattle Symphony and has most recently been performing with the Houston Symphony.
