gibson faded cherry

the question of his guitar.?
Ok, so I played a Gibson V-cherry boxes need a watt amplifier Retro FX 200 (RFX200). love the setting and looks great in volume .. but I realize that my amp sounds trebely most of the time, almost metallic and again here. I the habit of playing the "leader" channel (lots of metal c decreased recently, but also use it for my classic rock and others) with my gain to 7, below the elbow, complete media at 8 and my "triple play" again at 6. suggestions about how to obtain a more complete my amp?
recover treble a bit and put the mids at 10. The guitar is a midrange instrument. So if you still have the problem … Place an EMG 85 (Active humbucker) in the bridge position.
