So while I wait for the lazy admin staff over at PlexiPalace to approve my registration, I thought I'd come here to find the answer to my simple question: I bought a 100W Marshall Super Trem off the 'Bay that was listed as a '73. Turns out it was a '70!! (I'll have pics of it posted soon). Around the same time, I aquired a '72 1960 slant cab with 4 Celestion 25W, 8ohm, G12-M speakers with 55hz Bass cones. Is there a mod that is required in order for me to run the head and cab as a half stack or is this already a match made in heaven? Thanks in advance!
