I recently purchased a furman power conditioner, a korg rackmount tuner, bbe sonic maximizer and a isp rackmount noise reduction. Real cheap off ebay and Im looking to get a decent rack unit and get a tighter cleaner tone but im a noob when it comes to alot of this equipment. I was wondering what else i should look into to complete my unit.

Also i see alot of people on you tube talk about they're power amp and pre amp what exactly do these two do to your rack and tone?
A power amp and preamp together make up one singular guitar amp.

Greg what did you send me??
To put it super basically,
preamp = guitar tone
power amp = volume

The power amp still contributes to tone though, don't skimp out on your power amp.
