AC/DC is a gift from God. Malcom and Angus set the standard for classic Marshall tone.

That intro riff to Jailbreak has haunted me my whole life. It is one of the most unique tones in rock and Malcolm hasn’t exactly had it again in any other song. It’s just all bark with zero sizzle. Have never had an old Marshall or newer amp, that even when set cleaner, have no sizzle and that kind of clanging bark.

Yeah its the ultimate rhythm guitar riff played by the ultimate rhythm guitarist! When you say sizzle are you meaning that kinda fuzz/fizz when the amp starts to break up?

Trust me this amp OF MINE sounded ordinary. Jason using a Les Paul with Humbuckers in the clip made it sound good. BUT with a hollow body Jet with 3.9k output Filtertron pickups it sounded woeful with no balls or volume whatsoever. Wait till part 2...

A video on the Baxandall plate fed tone stack could be interesting. Maybe we can explore a bit more about what Marshall was doing here? Please like this comment if anyone else is interested. I have been studying ACDC tone for years and I think this is closest I have ever heard.

I actually like the sound of when the amp came in. It sounded cleaner and less fizzy or more like early ACDC which I have always preferred. this is my humble opinion. :). however I also loved the sound after Jason tackled it. I would be interested in a video explaining the differences between shared cathode and plate-fed tone stack.

Malcolm Young had my all-time favorite guitar tone. As someone who almost only cares about rhythm guitar, his tone and play style were the absolute pinnacle. Not much gain, bright but not ice picky. The power came from his right hand, and where/how he picked/strummed. Just the perfect hard rock rhythm guitar sound.
@MichaelSorensen-bl3ec

Sounds pretty good. I'm always surprised at how clean Malcolm's tone actually was, I think it was a conscious decision so that his parts would mesh with Angus's more dirty tone and both would be clearly audible. That "Rock & Roll Singer" riff was re-purposed by Billy Duffy of The Cult in a song called 'Wildflower'.

I have built around 10 tube amps from the bottom: 1987, 18w, 2204, AC30, Princeton ... and modded a lot of different amps. I have followed a lot of builds on YT, and read a lot of the tube amp books around. 2 things that make me wonder is: 1. Why don´t amps builders experiment with cathode bias ?? It is easy and sounds very good in VOX, Matchless and some older Fender amps. 2. Why don´t amp builders use the Matchless type post inverter MV ?? It puts the PI into play, and sounds very good in Matchless amps. I think about building a 50w Super Bass with cathode bias, Post PI MV and only plastic caps in the whole amp. SCR makes some 650v plastic caps that can be used for PSU caps, at reasonable prices.
@bobtuiliga8691
7 ай бұрын
The negative feedback and dissipation of cathode biasing becomes more of an issue with larger tubes which is why you usually see it used with smaller tubes, especially EL84s/6BQ5s as they only require a few volts bias. You do see it on bigger tubes from time to time though
