#### Topic: Bocal lengths

This sounds like such a stupid question, but here goes.

I understand the difference in pitch between various bocal lengths, but can this be quantified? How much sharper is a 2 bocal than a 3? Or a 1 over a 2? Is there a difference between manufacturers (yes I know that Fox bocals are one number larger than an equivalent Heckel)?
