Interstate Zed

Based on the Dr Z® Route 66


(no mid, no presence, no master)
One of the most original and successful, designers and manufacturers in the contemporary “boutique” scene, Dr Z is known for establishing new tonal templates, rather than cloning the vintage standards. The popular Route 66 is perhaps the best case in point: based around a pair of KT66 output tubes (a ruggedized, military-spec version of the 6L6), with an EF86 pentode in the preamp, the Route 66 manages to make the most of high-end “ultra-linear” output transformers that are popular in the tube audio world, but have foiled guitar amp makers for decades. The result is an amp that achieves an extremely touch sensitive, full-bodied “milkshake thick” overdrive when pushed, without ever losing its impressive clarity and definition. In short, a new and original classic.

The Route 66 features a simple tone stack, consisting of Volume, Bass, and Treble, which feeds a non negative feedback Phase Inverter, for true harmonic content and full output tube dynamics. It has a GZ-34 Tube Rectifier to complete the round enveloped tone. The amp has piano-like clarity with endless sustain, even at low volumes. Its 32 watts truly sing when driven hard in a focused, thick distortion, with a tightest bass response.
Treble and bass operate regularly until 50%, and dial in gain once turned past 50%.
To put this amp into overdrive, crank all three controls (Drive, Treble, Bass), use humbuckers and possibly an overdrive pedal.
