For sale is my Dr. Z Route 66 head in very good condition and perfect working order.

If you're looking at this listing, you probably already know what the Route 66 is: one of Dr. Z's most revered designs and a true boutique classic. Built around a pair of KT66 power tubes and an EF86 front end, the Route 66 delivers the thick, harmonically rich British blues tones that made the original KT66-powered amps legendary.

This is not a Marshall clone. It's Dr. Z's own take on the big, dimensional KT66 sound with incredible touch sensitivity, huge note bloom, and outstanding cleanup from the guitar's volume control.
