Heckel (37) / Fox 19

F#+low-E connection on the butt-joint

Use:
Facilitates slurs between low-F# (R-4f) and low-E or lower notes.

Note:
To use this option, one must play low-F# with R-4f; on some bassoons, this F#-tonehole is too flat for use in the low octave. (N.B. This does not apply to bassoons with F#-toneholes of matched size.)
