What is an ABC?

Developed by Chris Waters and the engineers at Ray Farr Flugels, the new Tom Hutchinson Adjustable Bottom Cap (ABC) replaces the standard Bottom Valve Cap on a piston brass instrument. Over the past six years our previous Heavy Bottom Cap model for Sopranos, Cornets, Trumpets, Flugels and Tenor Horns have proved very popular worldwide.  

How does it work?

Adding mass which reduces the harmonic partials (the full spectrum of sound colour within each semi-tone) is the science behind our Adjustable Bottom Caps, acting positively in terms of centering/securing notes, aiding sound and projection. The ABC can be used on either the 1st or 3rd valve; your choice. The proof of the pudding is in the blowing however and we offer a 1-month trial period with a full refund guarantee. 

What do the weights do?

There are four different weight options to use on the ABC and each combination of weights gives a different sound, depth and tone, allowing the player to adapt to whichever style needed. The extra weight gives greater stability in all ranges, helps the player produce more centred notes and improves production and control.

Every ABC is finished in bright silver plate with 24 carat gold trim.
