Hi Scott,
I use
Evidence Audio cables - good solid reliable cables that don't degrade my sound at all, and don't get tangled easily! There's not much you can ask of a cable beyond not really noticing that it's there. If you're having to pay much attention to a cable after having bought it, something's wrong. The Evidence Audio stuff just does the job.
I rarely use a strap, as I sit down to play most of the time, but when I do, I use Comfort Strapps.
cheers,
Steve
