with regards to deathism's post
i had a session previously just once, ONCE.. (i may not be totally tone-sensitive)
however i tweaked a few pedals and noted down several settings on my pedalboard (its not really mine) before going to a jamming studio too...
upon reaching, though its a different amp, (both solid-states), the sound coming out from the box seemed better... lol. its some peavey but i'm unsure about the amp.. mine's a roland...
maybe cranking up volume does make a difference?
and... to me, lotsa solid-state amps' clean channel dont really sound very far from each other..
just my 1cent..
