A few issues ago, Guitar Player magazine did a test of over a dozen different cables. They found some pretty wide differences between them.
With creating music, the sound and tone of everything in the signal path will matter.
I have built a NITRO level guitar cable for my son. I also built him a single ended, tube, head with a 12" hemp cone loaded cabinet.
If you are interested in trying out the cable, pjchappy, send me your address and I'll send it to you for an audition.
