Mods and upgrades

A classic Marshall
My Super Bass is from 1971. This is the amp that John Frusciante uses, since a long time. I use it with guitar, and it's just an unmanageable monster, it's beyond loud. For achieve the "right" Marshall sound, you have to set the volume at 6-7, and it's just too much for almost any venue. You can use an attenuator, or something like that, otherwise it's impossible to use. You can use it at 2, but it's just a clean amp, and it doesn't make sense at all. If you use it at a proper volume, and push it with a simple overdrive, you have the iconic sound you heard on many records.

“It was just the best amp that I’d ever had in my collection. And it was so roadworthy,” Page says. “It did all those Led Zeppelin tours, and all the recordings,” Page says. “It did flippin’ everything.”
Paul McCartney used the Marshall Super Bass amplifier during the recording of the album "London Town," as evidenced by a photo from Maccafan.
Around 17:15 in this rig rundown of the Rock or Bust tour, Angus' tech mentions that they have two or three Marshall Super Bass heads (production years not mentioned) that get cycled in and out of the 9+ head rig that they use.

My first amp was a really nice amp, actually: at the time, nobody really wanted ’70’s amps. It was a 1971 Marshall Super Bass: it had an amazing tone, but it was nowhere near loud enough for me and it was always breaking.
