I am searching for a two EL-84 amp to play clean to dirty using the volume control, mostly with a maple neck Strat and occasional OD pedal. I would appreciate comments from those of you who have owned and/or compared TWO or more of these amps: 1.) Goodsell Super 17 2.) Matchless Spitfire 15 3.) TopHat Club Royale 20 4.) Marshall 18w 1974x and clones? I have played the Goodsell Super 17 for a day at my house. I especially liked the clean to distortion transition and how it responds to pick attack. I was not impressed by the build quality for the first generation with the tiny chassis and found that it ran the tubes way too hard (16 watts idle dissipation for an EL-84!). The Mk2 version has the tubes and everything spread out more, so the reliability should be better. Head or combo form is available, as is reverb, a $300 option. These are local to Atlanta where I live, which is an advantage other than having to pay sales tax. The Matchless Spitfire 15 appears to be the prototype for the Goodsell Super 17. They have the same set of controls. Not sure of tonal differences as I have not played a Spitfire in 10 years. I suspect the Matchless has more headroom due to larger power and output transformers. On the other hand, part of the charm of the Goodsell may be due to output transformer saturation as the volume is increased. The appearance and build quality, imo, is superior to the Goodsell and the price is only a little more. I understand that most Matchless EL-84 amps run the tubes pretty hard, too. The current version is available as a head, small combo, or the larger 1x12 combo with reverb. The latest version of the TopHat Club Royale 20 appears to give the most bang for the buck. They have recently upgraded the transformers to larger, Heyboers. The rectifier is a 6CA4 now instead of 5AR4. Preamp tubes are TungSols, probably the best in new production. The treble/mid/bass EQ section allows for more adjustment than the other two amps, which have only a "tone" knob. However, this does not necessarily equate to better tone! Other features include a Fat-Off-Bright switch and Cut control for the power section. Appearance and build quality is on par with the Matchless. I like the top-mounted controls, which are easier to see and adjust when standing up. Apparently available as combo only. (I am aware of the upcoming Sweet 16 / Mini King Royale head.) Also, if you have compared and preferred some other two EL-84 amp, such as the Marshall 1974x or clone, please share your thoughts. THANK YOU!
