I just received this set from Jason at BassStringsOnline. I started stringing them on one of my Spector's and noticed I needed to notch the nut wider a tad more. I don't want to alter it anymore so I am putting these up for sale here. This set is the Heavy DDT 55 75 95 115 135. These are one of the BEST strings for drop tuning D, C# or C tuning. The only thing I did was cut the D and G string while I was putting them on. I always cut 6" long past the tuner post and my Spector's are 35" scale. Again these are new and unused. These are $30 plus shipping. $22 Shipped ConUS Lower48 Only.
