First of all, MOSFET amplifiers are a much better choice for ... When the tube amplifier is "overdriven" by transistors, the transistors can really be heard. An all tube design is needed for a clean sound. Thus, noise gates were invented. A simple straight forward tube amplifier design works best for guitarist.
