hi, i've got a studio pre and i'm gonna buying a Mesa 50/50 soon. Since i can't reach exactly that scooped Metallica's tone even with the built-in graphic EQ set to the classic V (the tone is still too sweet and juicy), i was thinking about buying a graphic eq and put it in the loop of my pre or eventually between the pre and the poweramp... i want something not too expensive and i thought for example of a MXR 10-band eq.. what do you suggest? 8)
