I am liking the EG3/4 X. I think if I only played by myself at home....I might keep it stock...but with the band, I think I'll be heard better.
Really, I find it kind of Marshally with bigger low mids.
Now, I don't think it does the JCM800 thing as well as the SL2 or SL2X. You guys? In fact, I think I prefer the SL2 stock. I think its cut is fine. I actually found the EG3/4 needed the additional presence and cut, for me - not the SL2. That is like a smoother Marshall, fine by man. The EG3/4 gets the growl and upper mid award....plsu as you said it is still thick.
By the way, my EG3/4 X is a touch different. It has the upper mids but the highs or treble are not as....high, LOL. I have a slightly different cap but I think it is a minimal difference.
