Professionally built on a custom made aluminium chassis with a superb solid oak dovetail jointed head box.
2 X Sovtek KT66 power valves, giving 30-35 Watts.
1 X EF86 (new old stock)
1 X JJ ECC83
Ive recently added a master volume control to ‘tame the beast’ & glazed the front panel to show off the workings.
About the Dr Z Route 66
The Route 66 is an all original Dr. Z design based on the incredible KT-66 tube originally built by Genelex. This tube generates the “Milkshake Thick” tones, as heard on John Mayall’s “Bluesbreaker” album featuring Eric Clapton (the “Beano Album” as it is known to many).
This is not a duplicate of the Marshall JTM-45, but completely original spin with new tonal end results. The Route 66 has an EF-86 front-end. For those not familiar with this tube, it is a 9 pin pentode that offers incredible gain and input dynamics. It is normally used in high-end stereos, most often for its accurate transfer of input signal, balance, and headroom.
The Route 66 features a deceptively 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.
I fell in love with amp very quickly – I’ve owned a 1966 JTM45 and this comes ridiculously close to that tone..if not excelling in some areas. However, as with the JTM, roll back the single volume and it loses clarity. I got tired of grief from front of house PA guys about the excessive volume’s I was having to play at in order to achieve the ‘magic’ tone and have recently added a master volume to try and make it more manageable. Currently, I am undecided.
I know if I only played stadiums then it would the one – no effects, and a waa pedal & a booster for leads – with the addition of a tube powered vibrato and ideally a reverb too , this has the potential to be my ‘perfect’ rock amp.
Initial tests at lower volumes with a pedal infront haven’t thrilled me, but I’m not ready to give up on it yet.
