I have a pair of EMG-SSD (Stuart Spector Designed) 4 string passive soapbar pickups in excellent condition. I pulled them out of a Spector Performer 4 bass that I bought new a couple of months ago. They have a great sound and are similar to the EMG-35HZ pickups. They are the same size as the HZ's (3.5 in x 1.5 in) I wrote Spector customer service to find out the difference and similarities between the EMG-SSD vs. the EMG-35HZ. Here is an exact quote of what the customer service rep responded: "EMG-SSD -pickups are made in China, like the bass. -designed for us by EMG -passive, humbucking design -a little darker sounding vs. EMG-HZ EMG-HZ -pickups are made in EMGs factory in California -designed and built by EMG -originally made just for us in the 90s! -passive, humbucking design -EMGs passive version of their active humbucker, so -the tone is brighter than our EMG-SSD pickup. Quality is about the same." $40 (this includes shipping) and their shipped to your door anywhere in the lower 48 states of the US ONLY. If interested, send me a PM or an email at email@example.com Thanks!!!
