I've also heard the ceramic Jensen reissues can be nasally.  How much could that speaker be involved, and what would be your speaker suggestion?

Thanks!  I will put the buffer in shortly.

I have a wild question to ask:  Would it be possible to add the reverb and tremolo units in the Heath to a 5e3 clone? 

I have a Heathkit TA 27 that has a great clean with very little treble, but general lack of brightness greatly effects any slight overdrive or fuzz used.  The problem gets worse when to achieve anything close to brightness, the bass must be turned all the way down, killing any "chunk" or low end dynamics.  I'm looking for any possible mods to brighten up the amp but not lose the dark warm tones already there, and allowing more range of use with the bass and treble.  I have a link to the schematic below.
