I replaced the pickups on my matte black SG Special VE with Artist Guitars 'bullbucker' humbuckers and wow! Huge improvement. I compared to a SG400 Pro in the local shop and my Special VE sounds better. I do notice that there is a huge jump in volume from just past '2' on the volume knob, and the tone seems to not make much difference from '6' upwards. Is this normal? Still sounds amazing, especially through the Boss OS2! Would upgrading the pots etc. result in improved controls?
