일부를 발췌해 보았음... (밸브기타앰프와 솔리드 기타앰프의 장단점...)

위 사이트에 솔리드 앰프의 하드 클리핑을 소프트 클리핑으로 바꾸는 방법도 있고요..
전자기타의 기본지식과 코드 잡는 방법까지도 들어 있네요..
중생님께서 번역하여 <연재>형식으로 올려 주셨으면 합니다...
Guitar Amplifiers - Valves vs Solid State
This is a subjective topic, however, it is the collective opinion of the vast majority of electric players that valves sound better. One result of this opinion is that nearly every solid state guitar amplifier produced is marketed with a claim to reproduce valve sound! A look through any guitar music magazine will show proprietary names such as ValveState and TransTube!
Here are some of the pros and cons of valve amplifiers:
Pros:
Smooth transition into clipping (RMS power is usually quoted at a given % THD)
High dynamic range (because the onset of clipping is not as noticeable around the full power rating)
Overdriven sounds are "musical" (ie smooth and not harsh)
Various models produce consistent standard recognised sounds
Limited bandwidth (amplifier and speaker in combination typically cover around 80-6000 Hz)
Cons:
Amplifiers are heavier, due to the requirement for a speaker transformer and larger power transformers.
Valves typically need to be replaced up to once a year to maintain peak performance.
Valves are noisier (both hiss and microphonic components)
Amplifiers run hot (and very few include cooling fans!)
Expensive to buy and maintain
Leo Fender had a background in radio, so its fair to assume he did not design his amplifiers in the 1950s with any thought of controlled and sustained overdrive. Rumour has it that his first design was straight out of the RCA valve handbook!
With the help of field tests with musicians of the day (notably, guitar-pick-melting American surf guitar guru Dick Dale), he clearly intended a physically and electrically reliable design to withstand use and abuse by touring performers. It just happens that the combination of his (electronically) robust design, and the natural overdrive characteristics of valves produces the trademark guitar sound used to this day.
