We offer Three Standard Models:
FLM - Medium funnel shape with a #20 bore size. This model has a lighter sound and is preferred by players who need to play in the upper register.
FL - Standard deep funnel shape with #16 bore size. This has been by far our most popular model over the years.
FLX - Extra deep funnel shape with a #14 bore size. This model is capable of producing a most beautiful classic Flugelhorn sound for orchestral and other large ensemble work.
Plus our Wide Rim Option (W) - Any of the Trumpet, Cornet, or Flugelhorn tops can be ordered with the W rim option which provides an additional 0.020 inch (twenty-thousandths of an inch) of outside diameter for players accustomed to slightly wider/fatter rims. Note that the W option is not available with the Signature models.
