Re: Tweed Amps - Which ones are they
Let's take it apart a bit. I'll be very general here and probably will screw up something that a few other, more expert will correct me on, but they didn't take the time to write this...
THe early Fender amps were covered in a tweed material. Hence the name Tweed Amps. It references the Fifties models for the most part. Lots of mids on these amps. Very raw sound.
Then in the very early 60's, the started putting brown tolex on their models and the controls got moved from the top to the front. The plate behind the control pots were brown for the most part: hence, the name Brownfaced. They added some vibrato/tremolo to some of these models. That kinda sucks a bit of the raw tone away IMO.
Then along about, what, 63 or 64, they started using black tolex and black faceplates (I've even seen a brown tolexed amp with a blackfaceplate, like Leo had some left over parts or something) and we call those amps, the Blackfaces. Oh yeah, they started adding Reverb to those Blackfaced amps and the world has never looked back. The left the vibrato/tremolo on there as well. Tone-wise, these amps are a little softer on the mids.
Along about 68 or so, Fender got sold to CBS (I think) and they decided that those awful Blackface amps distorted too quickly. We must fight off Marshall and the others, so we'll try and give our amps more clean headroom. The results were generally thought of as being a bit on the sterile side of the tone spectrum. They're often referred to as Silverfaces because they left the black tolex, but put silver faceplates behind the controls.
I have a first year silverfaced Pro Reverb. When I got it, I rewired the circuit and turned it back into the Blackface Circuit from the previous year. Amp now sounds better.
Now to address your question, there is a Tweed Champ (1x8), Tweed Deluxe (1x12), Tweed Super (2x10), Tweed Bandmaster (3x10), Tweed Pro (1x15), Tweed Bassman (4x10), Low powered Tweed Twin (2x12) and probably some others I'm missing.
As far as tubes, the Tweed Champ and Deluxe used 6V6 power tubes and the rest of them used 6L6 power tubes.
That Fender Field Guide link above has a WEALTH of info on all the models, what tubes they used, etc.,. I've spent countless hours there.
