cathode resistor/cap question- split vs shared

[Strat0kaster]

Hi All,

Simple question: is the split cathode "model" of a shared cathode amp really equivalent in terms of sound, feel, interaction between channels, etc.... ?

I'm toying with the idea of running a 1.5k/5uf and 2.7k/.68uf split cathode on my JTM50/JMP 50 mongrel. I like the current shared cathode I'm now running 820/10uf, but I find myself wanting more of the true "lead" sounds at times. Electrically, the 1.5k/5uf split normal channel and the 820/10uf shared normal channel should be roughly the same (obviously 1640k would be ideal). My question is, will these have the same "feel" ? Are there any other subtle differences?

If not, it would seem like an obvious choice for anyone to run 1.5k/100uf (or 110uf) and 2.7K/.68uf split to get the "best of both worlds" ?? I should also mention that I'm not running a mixer bright cap, and use a 100pf cap on both volume pots, so the 2 channels are the same other than the V1 coupling caps, which are .01 for normal and .0022 for the bright.

Thanks!

i'm also curious about this. I don't like the 820/320uf. Way to boomy and sub-bassy. Maybe i'm going for the fenderlike 1.5k/25uF
