I never back off the Tone, preferring maximum brightness at all times, so I intend to use the Tone Pot hole for the BP Volume Pot and have no tone Pot at all.
The Ibanez Fretless I own is a PJ style using Ibanez's Own PUs so Unsure of their equivalents.... and they are not the Standard sizes so I can't swap them out to try the sound.

I am certain I can do this, I just want to make sure I buy the right Pickups First time as I am very limited in the budget Dept.
Leaning very much towards getting an Entwhistle Neodymium Bridge Pickup along with Stock Squier PB Pickup as a starting point.

Ideally I would be using Seymour Duncans but one of those is worth almost twice what the Bass cost to start with......
