These guys are morons. You stick a metalcore in front of a windsor it will sound like absolute crap. How do I know? Because I have both.
For the windsor, i suggest getting a ts9 or ts808 tube screamer pedal or something close to it.
for the spider, honestly youre probably better off getting that floor switch they have. it adds a bunch of new effects, not just more distortion.
Honestly, one of my favorite "normal" distortions is the DS-20. The only problem is its a bit noisy, so it doesnt get absolute kudos from me.
Anyway, windsor with a ts9 in front of it
