heaps of guys here including myself have used the Tone Riders from the PGB store and have good things to say about them. I used the Vintage Plus I think. I'd stick with the single coils because that what makes a tele a tele , to me anyway, its that twang. There is a point of diminishing returns where like a lot of things you are paying for the brand rather than the product , SD's make great pick ups, no denying it but are they worth double a set of Tone Riders? Only you can decide.

Second hand.....why are they selling them? Did the soaking in beer experiment fail? Just like used cars really, you take a punt.
