Hey Ed !
Its actually the Gain as well as the Tone stack plus the Cap .... and yep it does ... I posted some clips at "the other place" comparing the same L.P vs the same Legacy Profile at the same varying settings .... and the differences are very, very stark ... a clip obviously though cant convey feel and dynamics
Not totally sure what you mean about the "base character" but each LP now does
not use the old legacy generic "amp base" ..... you *can* if you want re-insert the old "generic" stack .. but then you lose all the new benefits .... this is no doubt why the so-called Kemper Amp
signature that many of us all knew and loved/hated .... is now also gone ... although there is one poster here on TGF that swears its still there :) .. it isn't :)
Again, anyone one may love or hate or think L.P is total horse-sh%t ...
its all good :) .... that's kind of not really my actual point though.
If we are talking about fantastic great authentically tweakable raw Amp tones ... which I *think* we are, to leave out the new KPA approach for the current [and growing] list of 44 Amp Channels .... is just ignoring the current 2023 reality with the KPA.
