For years I have used ElectroVoice EVM12L's in my rigs but following a lot of experimentation have loaded one of my TwoRock 2x12's with Celestion G12-65's
Of course in my early career, I used piles of Celestion loaded cabs in the past by Marshall (G12M) and Orange (G12H) but fell out of love. Familiarity breeds contempt and all that! Recently I rekindles the love by buying a Germino Classic 45 and Vintage 4x12; fantastic!!!
They have a rich low mid and a lovely presence in the 2-4K region which really suits the Bludo. Davy Knowles recently borrowed my amp (liking it so much he ordered one) and was getting great results using a vintage Marshall Cabinet loaded with G12M.
I will shortly be recording a video tour of my rig and guitars. If you are interested, please drop me a line and I will add you to my mailing list.
Cheers and see you back soon!
