What model G12T-75s were used on AJFA?

[ABoyWithaTH30]

Does anyone know if Metallica used the vented 84’-85’ G12T-75s, or if they used the non vented 86’ or later first gen G12T-75 speakers in the 1960A cab?

Neither. 8 ohm Marshall Vintage speakers. Probably also used their EV loaded Mark series half back cabs, since it sure sounds like it

The Marshall 1960A and B cabs both came loaded with G12T-75s and some models also came with G12-65 speakers as well. MOP for sure used the 75s, AJFA also used them im almost 100% sure, but the first gen had 2 different models and they had different tones.

Maybe a better question is, whats the tonal difference between the vented and non-vented first gen G12T-75 speakers (early 80s white label)?

The vented ones have more midrange. They sound sort of like a higher wattage greenback and more similar to the G12-65’s. The non-vented first versions are more scooped in the mids with stronger lows and highs and imo better cleans if that matters. Both nice speakers, just different

+1 my exact analysis as well. I prefer non-vented later models.

A RTer has a cab very close to the serial# of the cab in the pics of the session. His has vented 75s. They were vented when first introduced in 84; and sometime in 86 the vents disappeared as I’ve had 2 cabs from 86 one with vents, and one without. Braintheory’s description is spot on.

One way to spot an 85/86 cab; the cloth fades to brown over time.

They never used angled cabs to record or get their tone live

While I don't disagree with this assessment, please let it be clear that when you're talking about non-vented early ones (with the serifed font label), they are no where near as scooped or even fizzy as the later ones were.
Source: I got both.

But yeah, the vented ones are pretty close in sound to a G12-65 and apparently the only technical difference was the coil former material; glass fiber or kapton.
