Bringing together features like an armada of 12AX7 and EL84 preamp and power tubes, onboard tremolo, reverb, and three-band EQ, and dedicated controls for pre and post gain, the Peavey Delta Blues 115 30W 1x15 Guitar Combo Amp covers the whole tonal spectrum of what blues players demand from their amps. The 15" Stephens True Sonic Speaker takes the 30 watts of power through the whole gamut from beautiful tweed cleans down to dirty searing distortion with the twists of a few knobs.
