This carefully engineered studio and live performance solution allows the true sound of your amp or loudspeaker  to come through by negating resonance artifacts that can muddy up the tone of your amp. GRAMMA yields nearly total acoustic isolation, resulting in a purity of tone that has to be heard to be believed! • A tighter, more focused low-end • Hear the true sound of your amp, loudspeaker or subwoofer • Instantly improve your sound on-stage or in the studio “Thanks so much for the cool amp stand and wedge! We’re fiddling around with it now at the shop, and it’s really remarkable how the amp responds! With a Golden Melody, it made the mids clearer and more defined… Great to see it’s Made In USA!” – Mark Baier,  Victoria Amplifer Co.
