The scooped Fender blackface tone is due partially to the circuit and partially to the inherent characteristics of the 6L6 tube. The 6L6 tube, at least the 6L6GC, has a stronger bottom end and less mids than an EL34 or even an EL84.Originally Posted by marnold
I think that EL84 tubes are chimey because they have a lot of top end, not so many mids and a relatively weak bottom end, IOW the tube emphasizes the top end. The EL34 is less chimey as it emphasizes the mids.
