I have built my own bass want to put 2 humbuckers in it with an active preamp. i would ideally like to find someone who will be able to make me some custom pole piece humbuckers to fit but is this possible? is it rediculously expensive? should i just go with Barts? anyone got experience of just putting them in a custom bass ie. not in the original music man position? and what preamp? should i just go with a standard bart one? or get a proper music man preamp? which will suit better? not really chasing an authentic MM tone just wanted somethin different from my jazz bass. thoughts?
