Hey Jimmy, I also have a set of superwounds on my homemade fretless that were put on in 1996 and still sound the same (not that the bass has seen much action since I bought my fretless rogue). They were obsolete even in 1996 but my local guitar shop in Worcester (where I lived for about 4 years) had a 'special' relationship with james How and had a batch made up specially. I really liked these strings as they were a 'half-round' profile that was ideal for my style of fretless playing, allowing my fingers to slide easily. I recently strung the rogue with D'addario chrome flatwounds and absolutely hated the feel - my fingers were 'sticking' as I tried to play a sliding vibrato - so they came straight off after the first gig and I've gone back to the DR red devils.
