Adjustable Spreader

Description

Martin Seibold Adjustable Spreader; max.length 70 mm; additional support in or in front of the tuning slide ensures a more robust, centred tone and improves the projection of the instrument (not suitable for reversed lead pipes); the effect is particularly noticeable on trumpets that do not have a factory-fitted tuning slide support; notes lock in more stably, especially in critical areas such as the upper middle range and high register; the instrument responds more predictably and with greater control overall; the length of the support can be adjusted for your own instrument by turning the claws
