hi! how much should I pay at maximum for a used studio preamp (in good conditions, retubed)? i come from italy, so i suppose prices for mesa products are a little higher here...another question: is it really capable of plenty-of-gain metallica-style metal distortions (black album)? even with passive pickups?does the distortion level depend also from which poweramp you are using?so how would it sound with a mesa 20/20 (price of this one used? :wink: )? sorry for the 1000 questions! thanks!
