Bach Backbore and Throat Specifications
Bach mouthpiece backbore and throat specifications. Reference guide for matching backbore numbers to cup designations across trumpet, cornet, flugelhorn, horn, trombone, and tuba models. Key to Backbore Specifications Except in general terms, identifying backbores by size isn’t possible, because they also vary in shape. Various combinations of size and shape darken or brighten the tone, raise or lower the pitch in one or more registers, increase or decrease volume. In each instance the effect depends in part on the throat and cup used with the backbore. Trumpet and Cornet Standard: Models without letters: 10 backbore "A" Cup Models: 24 backbore "B" Cup Models: 7 backbore "C" Cup Models: 10 backbore "D" Cup Models: 76 backbore "E" Cup Models: 117 backbore "F" Cup Models: 76 backbore "V" Cup Models: 25 backbore Special: No. 24: bigger, darker, symphonic No. 7: dark, Schmitt style No. 3: dark No. 117: favors the upper register, standard piccolo trumpet backbore No. 87: big, free blowing No. 76: bright edgy sound; helps upper register No. 41: bright, more resistant No. 57: lively, helps raise pitch on some notes, good high register.

Key To Bach Throat Sizes Numbers and letters are drill bit sizes. The smaller the number, the larger the throat. Generally, larger throats make freer-blowing mouthpieces with more volume possible. However, as the throat size increases, the upper register tends to sharpen; the player may tire more quickly. Trumpet and Cornet Special: No. 28, 3.57mm/.141" Standard: No. 27, 3.66mm/.144" Special: No. 26, 3.73mm/.147" (Standard Mega Tone) No. 25, 3.81mm/.150" No. 24,3.86mm/.152" No. 22,3.99mm/.157" No. 21, 4.04mm/. 159" No. 20,4.09mm/.161" Flugelhorn Standard: No. 22, 3.99mm/.157" Special: No. 21, 4.04mm/.159" (Standard Mega Tone) Horn Standard: No. 16, 4.50mm/.177" Tenor Trombone (small shank) Standard: 5.85mm/.230" Special: 5.94mm/.234" (Standard Mega Tone) E, 6.35mm/.250" F, 6.53mm/.257" (symphonic) (Standard 6-1/2AM) G, 6.63mm/.261" (euphonium or large tenor) (Standard 6-1/2AL & 5GS) 17/64", 6.73mm/.265" (Standard Mega Tone 6-1/2AL & 5GS) Bass Trombone/Large Shank Trombone Standard: 7.00mm/.276" Special: J, 7.04mm/.277" 7.53mm/.296" (Standard 1-1/4GM & 1-1/2GM) N, 7.67mm/.302" 8.1Omm/.319" (Model 1G) F, 6.53mm/.257" (Standard 6-1/2AM) G, 6.63mm/.261 " (Standard 6-1/2AL & 5GS) 17/64", 6.73mm/.265" (Standard Mega Tone 6-12AL & 5GS) Tuba Standard: 8.33mm/.328" Special: S, 8.84mm/.348" (Standard 24W, 24AW, 7 & 18) 9.00mm/.354" (Standard Mega Tone 7, 18 & 24AW) R, 8.62mm/.339" (Standard Mega Tone 12 & 22) Mouthpiece Express, LLC, PO Box 20239, Roanoke VA 24018 540.989.8848
