The J1 alto trombone is an indispensable companion for any solo trombonist. Its precision of intonation and especially its unparalleled responsiveness at the high register come in handy in demanding solo performances. J1’s tone is bright, as is required from an alto trombone, but it’s capable of warm nuances and has considerable richness and power of tone as well. By using a slide-tuning mechanism, we have been able to completely eliminate certain corpus imperfections that lead to adverse effects on intonation.
