Anybody who has owned these, commentary on the different tone between the three? Is SL2 a lot darker and smoother than SL? I had one years ago and it seemed darker according to my memory. I also had an EG3/4 which was darker than SL2. I owned SL2 and EG3/4 at the same time so I remember the darkness difference of those two. Never owned SL until now I own the SL+ which I believe is an SL with extra mid switch.
