Interesting thread. I have both the Bassman and the Tweed super I built both from scratch. The Bassman has cleaner tones and the Super with 6v6 tubes is used for distortion. The tweed Super with 6l6 is also nice. I have set up the Super so that I can switch the tubes and reset the bias and have either a 6v6 or 6l6 in a few minutes. The tweed super has the advance over the Double deluxe of clean tones and a more versitile tone stack. The transformers ae also custom wound. You can not go wrong with a authentic reproduction of these tweed amps if this style of tone is your bag. I use the Bassman and tweed together and I am in Tweed heaven !
