General Informaon
The SRZ-65 is one of Dr Z's first designs going back 20 years. This amp was ahead of it’s me. You get a tube
recfied EL34 output secon and a classic three 12AX7 cascaded gain front end in all it’s hand wired glory.
The tonal possibilies are vast. Gain and power combine to deliver pure crunch making this the ulmate rock
amp. Simply roll the volume back on your guitar and you’ll hear the shimmering bell like cleans from the
EL34s. The SRZ-65 is perfect for dialing up modern and classic rock sounds as well as old school Brish Steel.
Coming in at 60 was the SRZ-65 can handle stages big and small. The master and gain sengs allow many
different shades of clean to crunch. The full EQ and Presence circuit let you dial in the perfect blend of top
end, middle, and bass for your guitar. Single coil and humbucker equipped guitars are equally at home
plugged in to the SRZ-65. Around back are 4, 8, and 16 ohm speaker outs as well as a convenience AC outlet.
The SRZ-65 is available as a head only and matches up great with any of our speaker cabs…especially the Z
