I have had this Marshall for over 10 years now. I play it rarely and Gig'd it only once. It has been modded with a Half switch, and an effects send and return with level controls for each. It is the Horizontal input. It sounds amazingly phenomenal (but.....). I get 4 different levels between the Hi and Lo inputs and the High and Low power switch. It also has the Preamp and Volume knobs to interact with in each configuration (and still I wonder.....what if...... )

My Questions is: These beasts were forged with EL34s at the Marshall factory. Did Distributors change the tubes out for American sales to 6L6s? Or, is this a personal MOD made by someone aftermarket? AND: Can it be switched Back to EL34?
