Re: Dr Z route 66?
That amp (and most Dr. Zs) was designed around the more modern vintage-flavored ceramic celestions like the vintage 30 and the G12H30s. You'll have no trouble with those. Those give it the highest headroom, best bottom end as Christian said and probably a very loud tone also. I must stress that the amp IS EXTREMELY LOUD for 30 watts. Try cranking it up at a club or something, you'll be surprised how much you cant bring it up. But its very different from your typical Marshall or tweed in the way it reacts to things. For example, the volume knob - low breakup, but instead of getting more and more distorted, it just gets louder and louder as you bring it up as Chrisian said before. Tone knobs (treble and bass) bring the amp from very thin to very thick, almost like the control on the tweak fuzz, more like voicing knobs instead of high-end roll offs. Has a super smooth tone though, similar to a Bluesbreaker but with definitely some Vox and 18 watt influence with the inclusion of the EF86. Very simple design, great tone. I got a chance to play it a while ago with multiple guiutars and all volumes (hahaha never will get to do tht again!). I think it sounded best with P-90s and Alnico Vs (I was playing a '54 LP Custom Reissue). Strats and hums sounded good too, but the P-90 really stood out giving the smoothest tone and seemingly endless sustain. Id definitely recomend it...
