So I've pretty much used combo amps all my life. I just started thinking about preamps and power amp; I really don't know much about them. Based on the information I know, I kind of assuming a power amp is pretty much like a speaker cabinet. With that in mind, is it possible to run your guitar through a preamp pedal, and then connect that to a cab? I've just been thinking:

My guitar ---> preamp pedal ---> misc. cab = good tone?

EDIT: Also, assuming that works, what if you want to add reverb/wah pedals to your rig? Those pedals would obviously be placed BEFORE the preamp pedal right?

okay where to begin

pre amp is where most of the tone comes from in the amp
the power amp is what drives the speakers
most amp heads have the pre and power amps in the same thing enclosure and have an out to connect to the speaker cabinet

and i dont think a preamp pedal could power a cabinet

you can buy the power and pre amp seperately for a rack set up but thats usually expensive

if you want to add effects you could put it before the pre amp but some amp heads have an effects loop in which you could plug the effects into

It would be very, very quiet.

All the preamp does is raise the voltage by enough to drive the power amp. It certainly doesn't have enough power to drive a speaker, well, not a real speaker. The power amp lives in the head with the preamp on a normal amp, not the speaker cabinet.

Ah, so this could only work if it goes Guitar ---> Preamp Pedal ---> Power amp ---> Cab?

Yeah, but you'd get a better sound going guitar - rack preamp - rack power amp - cab. You'd probably be better off just getting a head.

yeah so you have something like...



and something like

http://www.fryette.com/poweramps.html

It's basically the thing as a combo or a head/cab.

A combo has the amp+ speaker in one package.

a stack has the amp in one box and speaker in another box.

a preamp/poweramp rack has the amp in 2 parts + the speakers as another part. it basically just has the 2 parts of a guitar amp in 2 different boxes.

you could always go the cheap route and get one of those Electro-Harmonix .22 Caliber power amps.
