Comparison of all four cabinets:
Same setup for all sound samples - Axe-Fx III with default amp settings on the Plexi 50W Jumped amp sim. I highly recommend you try that amp sim with default settings. It was the closest amp sim to my 1971 100w Super Lead Jumped and everything at noon works great. Fender Strat with Suhr pickups for the intros and leads. Gibson Les Paul with Burstbuckers for the rock rhythm tracks. Just an SM57 IR from each pack and absolutely no post processing apart from a tiny bit of reverb.
I'll give you guys a short history lesson here in case pre-Rola doesn't ring a bell. You've most likely heard of Greenback speakers. Although the modern Greenback is an awesome speaker the design for this speaker was completely different "back in the day" when AC/DC, Jimi Hendrix and the likes created rock'n'roll. The factory that created the cones is said to have burned down in the early 70s and with that factory went the secret formula for one of the main ingredients for the original Greenback - the Pulsonic cones. These cones have later been mimiced by other manufacturers but these are the originals. Some say they come close but having compared them side by side were still comparing a 50 year old speaker to a brand new one. The term pre-Rola comes from the Greenback labels saying Celestion and not Rola which happened in the early 70s. Some of the Rola speakers also have Pulsonic cones (I have two cabs with those as well) but if you have old pre-Rola speakers you're pretty much guaranteed to have Pulsonic cones.
The pre-Rola speakers can have a different size magnets, power ratings and cone specs. The most commonly used ones for guitar are medium and heavy magnets and a 55Hz bass cone and 75hz lead cone. So if you've ever wondered what the M stands for in the G12M25 - it's the medium magnet with a 25w power rating. If you've ever wondered what the H stands for in the G12H30 - it's the heavy magnet with a 30w power rating. So these four cabinets are:
The PR-M75 pre-Rola is "the Greenback" used by everyone from AC/DC to Eddie Van Halen.
The PR-H55 pre-Rola is the one that was used by Jimi Hendrix, Jimmy Page, Ritchie Blackmore etc.
The PR-M55 pre-Rola is a crossbreed with the medium magnet and the bass cone.
The PR-H75 pre-Rola is a crossbreed with the heavy magnet and the lead cone.
While the Pulsonic cone is the "main missing ingredient" I will say that the 55/75 indicator makes the bigger difference in tone. I love the 75 cones with humbuckers and 55 cones with single coils but obviously they all work great with just about anything. I would recommend giving the single mics a shot to get that raw vintage sound instead of a polished modern sound which obviously you can also do with these but I feel like the single mics emphasize the pre-Rola vintageness.
I'll be posting more clips next week so remember to follow this thread and be sure to ask me anything about these speakers. I have quite many of them and have experience miking them a lot.
