Sonic Vortex

TrumCor’s Sonic Vortex is a brand-new sound for your tonal library. Lay into it for maximum, bright sparkle. Pull back for a cool, smoky timbre. Various materials and scientific principles allow for this dynamic range of timbres. The fiber cone and maple resonator offer the warm, resonate tones. The spun aluminum base and vortex create the sparkle. The perforated, aluminum diffusor blend the tones for a rich, modern sound.
You have never played anything like it.
