hi guys! i have the first version of mark bass little mark . same sound,same watts,but yellow and 14,5lb heavy. i'm interested to know which between the PJ and the MB2 head sounds better. reading all around it seems a great head. i'm interested only in sound quality. i like uncoloured sound(markbass also has it). markbass starts winner on weight, 14,5 lb VS 40 lbs! does PJ recover and win for the sound?
