So after having the Route 66 for a little more than a week, I think I am in love. The amp is so expressive, its hard to explain, but its something you must feel rather than listen to. I have been playing a Maz 38 for the last year and while that amp has wonderful tone, its not nearly as touch sensitive as the Rt66. I was afraid the Rt66 would be dark as I have heard that form a lot of folks, but I dont find it dark at all. Its big and warm with very interesting mids yet cuts through a band mix easily. I LOVE how the tone controls work. You can really dial in a breakup point with them. Because the tone controls are not conventional, I can see how this amp is not for everyone. If you want MORE treble or bass, these controls dont really work like the ones on your typical amp or home stereo, they add gain to those frequencies. They adjust dynamic to the eq as opposed to scooping out the mids or something. If you like the basic tonality of this amp, its an absolute winner. Its not real clean and doesnt get all that dirty but its all places in the middle and its outstanding! I have to learn how to use my pedals with this amp because it will take them with so many more settings. I can have the Rt66 at 2 oclock and have a distortion pedal in front and it doesnt blow up!!?? What I am finding is that my pedals can be used for a larger variety now. I can have boosts, and even set something with a little dirt with little or no volume increase. Its great. I can go on gushing but must refrain. Its a lot of fun. If your curious about this amp, you owe it to yourself to try one out.
