So here is my delema. I have a JO5 and been wanting a DJ5. In on another thread we established that these two bases use the same pu's so they would sound very similar stock. I love the way that base looks so i was thinking of getting one with the J-retro in it, I never heard a DJ5 with one in it, so would it be a much different sound then the JO5? since the JO is more vintage sounding i'm wondering if a DJ with that preamp would be different enough to warrant a purchase.
