Without routing there may be problem.
Also dependent of the model of the bass. TRB 5p has at least three versions that I know of. If it's the latest soapbar model, no extra routing will be necessary on the body. The pickups are slightly wider than emg40 and about the same length.
Still, try the bass first. I like them as they are.
Yep! It's the lastest model with soapbar pickups. I really like the bass but thinking of changing the pickups to Nordstrand and Nordstrand preamp to see how that's like.
