I found the schematic for the MB500 Fusion head, which uses a 500k linear taper pot. I'll give it a shot, but does anyone have any experience with the GK-style contour/"voicing filters" that are used on a lot of bass amps? Any suggestions?
I actually bought the MB110 while searching for a better quality/higher wattage amp similar to the Crate BX25 combo, which I've had around for years and years but only recently tried reamping guitar through and was blown away. The Crate has a "Shape" knob and an on/off switch for the Contour, and 100% sounds very similar to the GK, but I keep it at 50% and it sounds great.
