The spring reverb and tremolo effect will also be pretty much the same on the amps that feature those effects - and they're the standard by which those effects are judged on other amps (and fx pedals.) The most noticeable differences between those amps will be ones which are pretty much obvious when comparing any kind of valve amp, so they remain true with vintage Fender models, as expected: smaller, low-wattage amps will give you a great crunchy tone when they break-up, with the volume cranked up; louder amps will keep cleaner at louder volumes; and amps with bigger speakers will sound fuller than the ones which have smaller speakers.Vintage amps don't have "Master" only "Volume" controls.Leo soon realised that amplifiers needed to be sturdy to withstand the life on the road, and decided to build his own, to care for the needs of travelling musicians such as his customers.
You'll see some big names such as Keith Richards, Joe Bonamassa or The Edge using vintage Fender amps onstage - but they can afford to, and it's no big deal to them.
These were easily the most powerful amplifiers commercially produced back then.
They all had the classic features we're familiar with now: heavy steel chassis, chromed control plates, and heavy pine cases covered with tweed fabric.
The list of illustrious British Fender users continues with Keith Richards (Dual Showman in the Sixties, Twin Amp now); Jimmy Page (Dual Showman in The Yardbirds), Pete Townshend (Bassman, Pro, Bandmaster and others); Marc Bolan (Dual Showman) and many others - so many, in fact, that it's almost pointless to try to create a comprehensive list of famous Fender amp users!
We'll just conclude this section by saying that, just like Fender amps have defined the rock'n'roll sounds of the Fifties and Sixties, they've carried on doing the same into the 21st Century: the Arctic Monkeys used a tiny, vintage Fender Champ to record most of the overdriven guitar sounds on their influential debut album; Jack White used a Fender Twin Reverb in the White Stripes, and The Strokes helped to popularize the modern Hot Rod Deville series, which is now a true staple in the setup of many indie bands.
It seems that, after many decades, Fender finally designed a series of bass amps that bassists can call their own!
