Guys, I'm considering buying a used MPG JJ4 bass listed on www.tradingbasses.com. It is gorgeous with a 5A quilted top and tobacco burst finish. I am curious if some of you TB'ers own an MPG and what do you think of the craftsmanship and playbility. I'm also considering a used Fender American Deluxe Jazz w/ upgraded shielding and Aguilar Preamp instead of the Fender/Suhr preamp. Which bass should I go for? I'm looking at getting either of these 4 strings for straight up slap/funk and jazz playing. I love a traditional jazz tone but both basses are calling my name...Need Help!
