hi! i readed that the PUP on the warwick fortress masterman is a dual Jazz Twin and not a humbucker. i tried a rockbass streamer, the one with only 1 PUP, and find it to sound great when it was with a humbucker, but VERY thin when using the single coil option. i have tha chance to try the MM before buying it, but would like to know if changing the dual jazz for a humbucker is a good idea. so if yes the dual pre amp wont be necesary, and so maybe changing the pre is an option. Ive always been fan of 3 band eq instead of 2, so maybe i could get a good 3 band eq pre, with the option of been bypassed, and the spare pot could be a passive tone control. any comment is welcomed, also recommending me posible hummbuckers and pre amps!
