I have a pair of EMG-SSD (Stuart Spector Designed) 4 string soapbar pickups that I pulled out of a Spector Performer series bass. These passive pickups are in EXCELLENT condition and are the same dimensions as the EMG-35HZs. According to Spectors customer service, the SSDs are comparable in quality to the 35HZs. They are slightly darker sounding than the 35HZs but nothing extreme or dark and muddy. They actually have a great punchy sound. That's why I picked up the bass in the first place. Make me an offer, if interested. Send me a PM or email at email@example.com.
