This EMG dual coil pickup works and sounds great. It is a drop-in replacement for the pickup in the Ibanez AGB-140, too. I had a pair of these pickups, and I used one in my Ibanez and I still have this one left over, This is a passive pickup that does not require a battery. The EMG 35 HZ is sized for 4 string basses. $40 shipped anywhere in the USA. PM your email address and I will send a Paypal invoice. Check out my stellar TB feedback!
