I'll take "what the interweb" for $100
your amp already has a preamp, what are you asking for?
Isn't Alex the host of jeopardy, and Pat the host of wheel of fortune?
Anyways, I used to have an Engl E530, and I thought it was a great sounding preamp, especially for high-gain stuff. You can usually find them used for under $400.
i have a mesa 20/20,
what kind of power amp should i get to hook up to it?
i was thinking should i go with solidstate? or tube? maybe a samson 260w?
i have a marshall 1960A cab,
what kind of guitar should i plug into the cab?
i have a set of stereo headphones,
i was thinking of plugging them into my metal zone, should i do this or should get a zak wild octaver and use taht instead?
:p x a baker's dozen
