I currently own a 5 string bass in which I swapped out the pickups for an EMG DC and TW. I needed to get the ones for a six string because the holes on my bass were exactly that wide. Now, this bass is nearly unplayable, and I was thinking of getting an Ibanez SR506 and putting those pickups on it and just scrapping the 5 string completely. Does anyone know how I should go about this? How do the Bart MK1's compare to EMG? I looked up pickup dimensions for the stock pickups on the Ibanez and didn't find anything.
