........I wouldn't have believed it if I hadn't heard it with my own ears!!!! It's not even the same amp!!!!! What a difference. If you like the sound of the DB's, then you owe it to yourselves to put in a MM OT!! It's no my main amp, and I've just been holding on to it as a backup, but now I think it will definitely stay in this mans arsenal. Go Mercury magnetics!!!!! Now I'm gonna put them in my Ceriatone 18 watt TMB and my Budda SDII 18-watt 1x12. already have one in my winfield too. It's the best $$ you can spend on an amp - MAJOR DIFFERENCE IN TONE!!!!!!!! Its not even marginal - like new tubes or speakers - the tone is indescribable!!!
