Dr. Z Amps - ROUTE 66 JR. 1x12 Combo - Black - Dark Checks - Gold Z Logo

We've been fans of the Route 66 for years, and when we heard about the new Route 66 Jr we jumped on ordering up this combo. Featuring the same simple, vintage-inspired controls that was a part of what made the original build famous, this 12-watt, single KT66 build delivers on that huge, dynamic and thick sound. For 2026 there are two new features to this amp, including a buffered FX loop as well as two additional steps of volume attenuation from 12, to 6 to 3 watts. 

Delivering that now classic Dr. Z combination of vintage American tones with a bit of that British chime and bite, this is a special sounding amp that we're excited to have here in the shop.

Additional description courtesy of Dr. Z: The Route 66 Jr. features the same time-tested EF-86 preamp, featuring a large, hi-fi pentode tube that delivers unmatched clarity, dynamic response, and headroom going beyond it’s smaller, more common 12AX7 sibling. This preamp is married to a Class A, single-ended Genalex Gold Lion KT66 power tube, cutting the tube complement of the OG Route 66 down from 2 to 1 and delivering 12 watts at full output. Quite a step down from the original’s 35 watts, the Route 66 Jr.’s output is enough to handle the stage but won’t have the patrons running for the door at full tilt.
