How much do you guys turn each of these sonic shaping knobs.......... (metal players only)

Is true that setting too much presence will make your sound go FLAT ??

I use a ROLAND CUBE 60 and I can't seem to get a nice tone ??
Tone is all ...... well probably 75%, in your fingers.
The rest depends on your wallet's thickness !!

Keep the faith, baby!!
Well in terms of time....I remember reading that Kirk took like 3 days to get his tone for MOP. It ususally takes me a few days of jamming before I'm completely satasfied, and I usually end up changing it later. Ss for the settings, different amps seem to have different EQ qualities, you just have to tweak it.
