Yeah my setup does sound pretty good right now.  When I play the "e" string though the high frequencies usually have a weak signal.  I have an Epiphone Les Paul, so maybe it has to do with the build of the guitar.   That makes sense, because when I go straight from my guitar to the receiver...

So if I get an EMG pickup for example, it will serve as a preamp?  I'm guessing if it does then that will solve my high frequency roll-off problem and cause less strain on my receiver.  

So yeah, if there is anything you think I could use in terms of tone or power or just my sound in general, any advice would be appreciated : )  

I appreciate the response.     My guitar is passive.  It has two humbucker pickups.    My speakers have an impedance of 8 ohms.   Now in comparison to other mini practice amps I've used (100-200$ range), my receiver setup far out ways what I could accomplish with those amps.  Albeit...

Alright, what does a receiver do?   Put simply, a receiver has two main functions: firstly, it amplifies the sound so it can be fed to your speakers, and secondly, it allows you to select the audio and video you wish to watch.     Alright, and what does an amplifier do?    ...
