If volume is tone, I think you'll be proved right.

Trouser-flaping-tastic.

Great when you get the volume up so high you can feel it. It gives a percussive thump you can feel in your chest. It's a rare thing to enjoy. Changes the interaction between guitar and amp. Can't imagine it's something that could be modeled.

Well put. It really does move some air.

In fact with the heatwave you're experiencing, perhaps this type of setup could be a more soulful alternative than a generic fan in the room!

And if you're ever in Northland...

Heh! Just stumbled upon this pic from the first NZG Gearfest I ever went to.

This is about two third of the stuff I brought. From memory there was a JTM45 and Marshall 4x10, a couple '81 Tokai LPs, pedal board and a dozen beer all fitted into a Peugeot 309GTI.

So rock 'n' roll Capt!

Couldn't you find a full size Les Paul? That one looks tiny...

I remember you firing up the Marshall and drowning out everything in the room

Rory Gallagher year 1985, now there's some tone (unsure what exactly what he had there but sure sounds 800).

Better late than never.
The JCM800 amps that were first made in '81 take the honours I think, those and the early JTM45s and others in the '60s, seminal stuff.
Here's some of my lot

'67 wasn't bad. They started the year with KT66-equipped JTM 45/100s, and ended with the first split-cathode Super Leads with Dagnall transformers. In the meantime, transitional models that became classics in their own right (e.g. the brief run of dual-rectified "black flags").

And that's only the 100 watters...

On the speaker side, you had both 20W and 25W T1221 Celestions (and 25W and 30W T1281s). And don't forget the pinstripe grille cloth and tall 1982B cabs!

Valve rectifier on the 67's?

I approve! I also used to own a 309GTI and it was probably the most fun to drive car I owned. Until I loaned it to a mate who hit a curb and snapped one of the rear trailing arms in half!

Never the 100 watters (exception of an early prototype or two).

On the 50W side, there were a few KT66 JTM45s at the start of the year, then the switch to EL34s, then SS rectifiers (including the coveted "JTM50" series). To further muddy the waters, there were the existing "JTM50" PA amps from '65/'66, and the relationship between circuits and faceplates became somewhat unreliable.

Good article that. Angus Young a 50 watt pilot, I never knew. Thinking about it, yes that gritty bite of a 50 is in that sound.

I had Ryan of Amp Shop a number of years ago build me an interpretation of a build year 1968 JMP50, SS rec' too, fits with what I see in that article. I was always curious to know what'd be like with valve rec' and a bit of sag.
That one in more recent times I changed out it's JJ EL34L to Mullard ri EL34, more mellow creature it is now.

Nice! '68 would be different again (split cathode, .68uf cap on V2A, 33k/500pf tonestack, possible 2.2nF coupler on the bright channel, filtering etc.), although that changed during the year also, so specifics will depend on the interpretation.

I just built a clone of a '66 JTM 45/100, which leads me to believe that was a pretty good year for Marshall too (wish I had an original). I guess they had a few of them!

Those earlier years probably were open to a range of interpretation depending on what the part bins offered. Defining point of vintage perhaps.

Absolutely! I've got a '69 Super Bass with three different kinds of coupling caps (mustards, blue/yellow Dubilier ones and those green Hunts ones). It wasn't until the early '70s that they started getting some consistency.

Fender on the other hand...
