Purpose-built for blues musicians, the Peavey Delta Blues 30-watt all-tube design generates substantial output that surpasses solid-state units. The three-band passive EQ, boost circuit, and tremolo with variable speed and intensity deliver the tonal flexibility required for both intimate sessions and full-volume performances. Includes an effects loop and external speaker output. This amplifier provides the sonic foundation and reliability that working blues players require. Does have some rust on the top of the control panel, it however doesn't affect the amp in any way.
