Electric guitar cable?

I and associates have also used with good results:

Canare (brew it yourself...long live soldering parties)
Dimarzio
Monster

Not cable but Wavelength audio makes a 300B based one-speaker guitar amp! List for around 5K. Gotta love it...

JPS Labs and Audience both make guitar cables but I never tried any yet. I gues if I was recoding or play out a lot, I would try one but I am not doing too much of that now.

I use a Tara Labs Decade cable for my bass guitar. Big difference in bass and mid-bass response. Anthony Jackson, one of the best bass guitar players in the world, is as tone obessed as Eric Johnson. He uses a Nordost Quattro Fil cable connected to an FM Acoustics single channel preamp, Krell monoblock, and custom made 3-way speaker cabinet. Audioquest is also making musical instrument cables. Hope this helps.

I use diy cables made with DH Labs BL-1 bulk wire (two conductor shielded).
