Peavey's exclusive HyperVent technology pushes bass through specially designed ports allowing the woofer to respond to its full potential. With 50 Watts of power that includes DDT speaker protection and a 15 inch heavy-duty woofer, the Peavey MAX® 115 is great for plenty of gigs and rehearsals. Another Peavey exclusive is the patented TransTube® circuitry that offers you a choice of three separate voicings MAX, Vintage and Modern each capable of emulating its own distinctive sound. The onboard semi parametric EQ offers some intense tone shaping with controls for low, mid, mid shift and highs.
