GAS Thaedra I (one) really floats my boat. Awesome build quality and very easy to work on if need be. All of the sheet metal is done on a press brake, no stampings of thin tin, all black anodized aluminum or nickel plated steel. All of the circuit boards are plug in and very easy to repair or as these forums like to do "recap". Also the knobs are solid aluminum for a great feel, not aluminum coated plastic. I forgot to mention the sound, it's the best I've ever owned, been at this for 40 years.
