While the numbering system of PeakTone trumpet mouthpieces is based upon a system developed for the Mouthpiece Project, it has many points at which it overlaps with that developed by Vincent Bach. However, it is not possible to say categorically that any particular PeakTone mouthpiece corresponds exactly with any mouthpiece from a particular manufacturer which is given a ‘Vincent Bach’ designation as there is so much variation between the offerings from different manufacturers.

The PeakTone trumpet mouthpiece range is currently offered for tenor instruments, these having a choice of trumpet, flugel horn and cornet stem offerings, the switch between these being made by means of the type slider on the stem setting. To see the stem type settings in action, click here.

Individual PeakTone mouthpieces are designated by an alphabetic code, i.e. a letter from A to Z, although each individual group does not span this entire range. Mouthpieces designated with letters from the beginning of the aphabet are deeper than those from the end, i.e., a mouthpiece designated A, were it to exist, would be the deepest of mouthpieces. The PeakTone codes utilised to describe trumpet mouthpieces will be: PT-ATB-M (alto trombone, not yet available), PT-TTB-M (tenor trombone, currently available), PT-BTB-M (bass trombone, not yet available), where the final character, here ‘M’, defines the size of the mouthpiece.

The tenor trombone mouthpieces provided range from Size H to Size P.

PeakTone Tenor Trombone Mouthpieces

The PeakTone tenor trombone mouthpieces range from Size H to Size P with Size H having the deepest cup and Size P, the shallowest.

The dimensions of the offerings are:

These dimensions are those used in the Peaktone model and the use of these will produce repeatable mouthpieces. However, they will vary greatly from the published data for Vincent Bach mouthpieces as no two publications can agree on exactly what to measure to obtain this data.

The Designations of PeakTone Trumpet Mouthpieces


PeakTone mouthpieces are designated 1 to 10.5, an additional letter being added only to aid comparison with commercially-available mouthpieces. A PeakTone numbered mouthpiece may be converted to any one of the variants for that particular number mouthpiece by means of the web site controls. The throats of all PeakTone trumpet mouthpieces are set initially to 3.66mm and the rim widths to 5.30 mm. Both these settings may be varied by means of the controls provided.

The sizes of the key features of the PeakTone mouthpiece range are:

These dimensions are those used in the Peaktone model and the use of these will produce repeatable mouthpieces. However, they will vary greatly from the published data for Vincent Bach mouthpieces as no two publications can agree on exactly what to measure to obtain this data.

The problem lies in the contours of brass mouthpieces which generally have no sharp edges for one to measure up to. The image below shows a fairly-typical mouthpiece cup.

The tapers of the shanks or stems of PeakTone trumpet mouthpieces are set to a default of 1 in 20, the actual dimensions being shown below:

 

The dimensions shown in red italic on the above diagram are adjustable by means of the sliders provided. The shank/stem Taper Start diameter (11.878) is indirectly edited when the Shank/Stem Receiver Outer Diameter (10.970) or the Shank/Stem Receiver Depth (25.4) are edited.
