no ST it doesn't show anything else than EQ (or Volume)
that is a snapshot of what's captured when reproducing those above mentioned samples
I've used Izotpe Ozone 5 (it's old but it's still working fine)
- the Purple line represent the overall freqeincies coming out from the Les Paul (let's say the EQ spectrum of that riff, If played on a LP
..or simply.. how the LP Sounds those notes)
- the Yellow line is the Lucille freq
- the Red line it's the difference/relation between the 2 EQ lines;
it means it's the EQ You shoud have to add, to apply to the LP's Take, if You'd like it to sounds more like the Lucille's take.
Or, if You want to see it on the other way, basically it shows How the Lucille Sounds (in terms of EQ and Volume) if compared to the LP: less high Mids, less Highs, just a lil more Bass, and generally a bit softer/quiter.
You can listen the average loudness difference in the stereo track above...the Left side is Louder than the right one.
a note About Loudness:
I have to say that I've setted both guitars in the same way, same action, same PU height, same strings and I also have to say that the SD APH II Slash (Lp) are a bit hotter than the 490s (Lucille);
of course if You Play them Unplugged, the Lucille sounds Louder than the LP..but when recorded...
And of course that graph can not represent anything about the feel, the attutide, the... smell.. of playing 2 differents giutars.
