My Favorite New Production "6L6"
Replaced a pair of Ruby 6L6GC-STR tubes in a PRS Archon and a pair of TAD 6L6GC-STR tubes in a 65amps The Whiskey. More refined, and better balanced than the Ruby tubes. Can't say I noticed a lot of difference as far as head-room but there is a much smoother break-up. The same can be said when compared to the TAD tubes. No where near as bottom-heavy yet still very punchy. Notes are more distinct and snappier.
