Filter caps..?

[crashtm1]

I've got a 2204 (JCM 800) I built 5 years ago...
It's always sounded thin even after many mods..

 Recently I started a 100 watt Plexi.. About done I decided to insert make it a
master volume,, basically another 800,,(2203)..
 This one has beautiful tone... Thick, full and very flexible gain , not grainy..

 Just recently I up graded the main 2x 70 if caps on my
Super reverb to 2x 220uf,,, wow!!!

   My question is this,,, if I double or triple the size of the
main caps in my 2204, will I see a huge improvement in tone??

Any suggestions???

Thanks..Crash...

I've always found the 2204 to be painfully bright w/o the obligatory 4x12 boxy cabinet.  Much of the shrillness is designed into the front end.  C1 = .68uF  I like a 2.2uF or greater.  C5, C6, & C8 can go away altogether.  This gives back a lot of the body.  This completely my subjective opinion.
