Inderbinen Alpha 100

This is one of Inderbinen's most popular trumpet models for a good reason.  It is easy to play and free-blowing with good intonation.  The sound is warm and medium-bright.  With both a traditional tuning slide and a tuning bell, the Alpha gives players freedom to customize its character and find their own sound.
