There is still that compression as it always has had, but it isn't as much.
However, at least with my setup on either Soldano, there is more clarity there compared to the previous regular SuperD that I was using. Now, bear in mind, mine has the aged cover so that also may affect how it...
I swapped out the stock JB in my Fender CS strat for one of these back in June. A 100% improvement! It is very slightly less output than the regular SD with a couple of slight changes to the mids.
Mine has changed over the past few years from what I initially posted - in order of my favourites:
1.) Soldano SLO-100R
2.) Friedman SSv2
3.) Bogner XTC 20th
4.) Marshall JVM410HJS
5.) Diezel Herbert MK1
I wish I could have kept all of them but I wanted to try other things.
Sincerest thanks for the the things you do around here to keep the place sane!
Hoping you can find the time you need to sort things out. Sometimes we all need a break.
I remember them having issues with the early vietnam built models years back.
I've had a 100W Stealth and 100 W EL-34 head through the years and no issues other than tubes. I would assume the 50s would be on the same build level.
