Hey all, I've been playing the snot out of my Mark Ir lately, and just thought I'd share a little love for it. I've spent the last seven years trying an assortment of amps to satisfy my blues jones, and the Mark I keep on smoking 'em all. The quest has gone throught the following: '99 Mark I reissue '68 Deluxe Reverb (gone) '65 Twin Reverb (gone) Fender Blues Deluxe (gone) Bad Cat Black Cat 2x12 (gone) '67 Super Reverb (gone) '66 Bassman (still love this too) Every time I have A/B'd the Mark I against any of the above, it wins every time for smokin' blues tone. I run it in a Mark IV head shell with a 1x12 EV loaded Thiele and a 1x12 MC90 loaded 1/2 Back. I just replaced the stock Mesa tubes today with ElectroHarmonix preamp tubes and the reissue Mullard EL34 power tubes, and it's better than ever. I get such an in your face blues tone on Channel 2 (the Blackface one)! It is pure magic with my '68 Strat. Just thought I'd spread the love, Stormin!
