Well here I am sat at work in my wonderful guitar shop bored to the dying breath then I decided to get
something done in terms of collecting knowledge so I lined up every cab in the shop with different speakers and decided to test them all with the original JCM800 2205 in the shop.
So here is my conclusion.
Vintage 30
Lots of high mids here with a dark top end, I've always been a fan of this speaker but hearing it next to other
speakers I hear this high mid peak that annoys people instantly very much in a range that hurts the old ear lugs.
nice overall tone though one of my favourites and really shines when u whack some volume through it.
Black Backs from 70s
Well this are Post-Rola Celestion Greenbacks and I think they sound down right horrid, really raspy and thin
no bottom end and none of that crunchy buttery mids that the Pre-Rolas provide, not impressed.
G12T75
Lots of highs lots of low end and a sizzling mid range, Im a fan I like it I think they're good but I must admit they have something in the high end that makes them sound somewhat brittle unless they're pushing masses of volume.
Hot100
Well these are my favourite so far tonnes of bottom with a thick dark mid range, tamed treble and enough balls to break your face open, they're essentially T75's without the harsh highs and extended low end. and for £29.99 each? simply cannot go wrong here I think everyone should try this speaker.
G12H30
Classic rock it's here! nothing but crunchy mids and great treble, even a nice rounded bottom. I'd suggest these also.
