I feel that the Gibson '57 classic plus pickup in the bridge is a very good pickup for the Angus sound. The black flag JTM would probably be the way to go for B&B type of tone. They started using preamps to sweeten up the sound during that time period, so you might not hit that exact tone but it's gonna get damn close. Mod the JTM45 to the El34 50watt OT and you'll get really close. I find that I get an excellent earlier Angus tone from a stock Metro JTM45, but I like the really early stuff. I think Angus used a JTM45 in High Voltage. If you go with the JTM45 then you can switch between stock and black flag version.

I have an SG with 490 pups. I am going with Angus signature in the bridge and 57 at the neck. You have a good point re the jtm 45 mod offering some flexibility. I also like the early stuff, it's raw and edgy.
Thanks

The Jtm 45 has a tube rectifier and the jtm 50 has a ss rectifier. What is the tonal difference?

what do you mean when you say high voltage. are you refering to the original 1974 aussie album or the 1976 european album? 7 songs on the latter were taken from TNT (the 1975 aussie album), 2 songs were taken from from the 1974 album.

490 pups aint bad. the angus signature pups have way more output than the old gibson pups angus recorded and toured with.

My 490's are open style puckups (2002 special) and I prefer the look of a closed pup with a cover. My reason for changing them is mostly cosmetic. You have a good point. Angus has said that he used mostly stock Gibson pups and that he didn't like to change the type, he paid more attention to how a particular SG sounded as a whole. I guess I could put a 57 at the bridge.

you can just buy covers for the 490. I believe the 490t has wider spacing then the old pafs.

a 57 will work, but it wont be much better than the 490

I built the metro 50 kit. and I have never played an amp that does a better Angus. the first time I played an ac/dc riff through it I got goosebumps. and I'm using a tele with a strat hotrail in it.

Great! What options did you choose tubes, trannys etc? How about MV control or do you use a Hotplate?

The SS* rectifier has a tighter bottom end, which usually means better bass response and sharper attack. This is usually good for the rhythm stuff, but I usually like the tube rectifier for lead work.

what do you mean when you say high voltage.


US version. Songs like Livewire and Rock and Roll Singer have that tube sag during the solos and just a little extra "warmth" that makes me think it's a JTM45. Oh, and the '57 Plus has a little of that extra umph than the '57 Classics. It just sounds really good for AC/DC stuff.

that's the songs from the original tnt album. on many of the solos you hear the room sound from albert's studio B (or whatever that small old studio is called again). it seems that the room resonates nicely. I'm not sure it is a jtm45 though. it could very well be a later el34 amp.

I got the stock trannys and the jj's nothing fancy. I installed the Larry/mark MV, It sounds great at rehearsal volumes but I don't like it at low volumes. I really like the jtm45's as well and If your more of a blues player that might be a better choice. but if your into the rock the 50 is awesome. I have to add that I didn't compare the amp to an actual AC/DC recording. I may be way off as far as replicating the actual tone, but I've been listening to them for as long as I can remember and it sounds pretty close to me.

:?
I hear the exact opposite of what you've described. Tube rectifiers have a "loose" low-end and a smoother attack, IMO. SS rectifiers are "faster" and usually have a tighter bass response (all else being equal). Filtering and other variables have an effect but tube rectifiers have more of a blues sound and SS is more straight-ahead rock, IMO.

It's pretty obvious that Angus used a lot of different amps and the various recording techniques played a role. One of the most appealing aspects of "AC/DC tone" is the contrast between Angus' and Malcolm's tones. One is raw and loose while the other is clean and tight. Put them together and something special happens.

I actually prefer Mal's tone and think a lot of people underestimate its effect on the big picture. Just my $0.02..........

OOPS, that was supposed to be SS rectifier. Typo on my part. Tube rectifier is looser than SS rectifier. I was trying to type that response at work and people kept talking to me....probably should have been working instead!

Also, I agree about Mal's tone. By far the most under rated tone and guitar player in my opinion. The way that Gretsch growls is awesome! I used to pull one of my small stereo speakers into the bathroom when I would take a shower and it just so happened it was the side with Mal in it. ever since then I've always appreciated his guitar playing a lot more.
