WHAT IS AN ADJUSTABLE BOTTOM CAP?

An ABC replaces the 4th Valve Bottom Cap. It is the same diameter and thread as the Valve Casing on your Instrument, with the BIG advantage being that you can try the 4 Weight options and find the one that works best for you and your instrument.


WHAT DOES IT DO?

From Students to Professionals of all ages, customers worldwide tell us that using an ABC has a very positive effect in "Centring and Securing the Notes in all Registers, helping to Slot them more accurately".

HOW DOES IT WORK?

This diagram details the Waveform of a Note when there is not an ABC weight added to a Valve Casing and shows the degree to which us brass players, as much as we try to keep the note in the centre, can lip the note up and down (shown between the orange lines) from its actual True Centre of the Note shown by the green line. 

The second diagram shows how by adding extra weight with an ABC to a Valve Casing, it Attenuates the Note closer to its True Centre. An analogy of this is when we used to turn the dial on an old-style radio to "Tune it in" and get the best reception, that’s the Attenuation achieved by using an ABC.


The science behind the ABC is that by adding Mass/Weight, this Attenuates the Lower Harmonic Partials, acting positively in terms of centring/securing the notes.

The science is interesting, but actually Trying an ABC is the Real Proof and that's where our 1 Month Approval facility Worldwide really helps.
