TB (Tina Brain) is a Paxman 4 rim modified by John Ward (very fine technician formally workshop manager at Paxman). The result is an exceptionally comfortable outer rim peak model, in effect the Paxman 4 rim Neal Sanders Style! The original is in Black Acetal and this combination provides exceptional comfort and protection for the embouchure.
The TB18 steps out the exact profile of the TB model by 0.5mm (0.020"). At this cup diameter the high peak does give the impression of a wide aperture which offers great flexibility low playing.
Available in 7 finishes.
Measured at 1.25mm (0.050") depth
