The initial model of the Tweed Deluxe in the Axe Fx II was based on my 58 Tweed Deluxe which Cliff borrowed during one of those "wanted: amps to model" periods in Sept 2012. I can't remember which epiphany and FW brought about the need to retest most of the amps after that, but I had my amp back in my hands when that happened, so if it did get retested, it wasn't with my amp.
Yes, there are lots of clones and it's a simple circuit, but there are vast differences between the results in my experience. When I bought mine it was because I was playing in a band with another guitarist using his own late 50s Tweed Deluxe and hearing this endlessly great tone pour out of it. I needed some of that glorious sound. He'd gotten the amp and then spent a couple of years tweaking it, getting the perfect tubes for it and the best speaker he could find (a Jensen p12p which he recently replaced with an Alnico Blue which significantly increased volume and sounds fantastic). I compared the one I bought to a couple of older Deluxes and a couple of clones in the store I bought it from and it completely smoked them all. After I bought it, I borrowed my friend's awesome Deluxe. Mine was super similar and the sound differences attributable to speaker differences were far greater than the differences between the 2 amps. They're both awesome.
I completely agree about the compatibility with a tele. I finally understood the beauty of a tele bridge pu when I matched it with the Deluxe which rolls off all the icepick nastiness. The bridge pu also puts out enough sound from the low couple of strings when driven to offset the fact that there's HUGE low end rolloff when the Deluxe is driven hard which makes the bottom disappear when using the neck pu.
One of the awesome things about the Axe and the Tweed Deluxe (and many other amps) is that in addition to all the great drive sounds, it's got a fantastic clean sound that has no headroom in the real world model. In the Axe you can dial the input drive and the gain WAY down and get a gorgeous super clean fat and warm sound suitable for jazz or clean country that simply wouldn't be possible with any volume in the real Deluxe. Conversely, you can gain it up and get it loud enough to compete with any other amp.
Also completely agree with Cliff about position of treble/tone knob. I have it almost all the way up most of the time. It opens up the amp lets it shine. I have the treble much higher than I would typically run it on BF Fenders or most other amps I'd use (low to mid gain).
