NEW TO GUITARNOISE - HELLO...

Hallo, I have enjoyed playing for a number of years, but I make better guitars than I do play them. Fortunately I have an Elder son who cannot make them, but can play something wicked. (He is my biggest critic).
I specialise in High end replica Strats and teles, and have received a number of commissions, mainly for 'Hank' signature Strats, with a couple of Jerry Donahue Teles thrown in. My main market has been Ebay, and have struck up quite a number of friendships via the sales, and component purchases. The creating is my main hobby, and has given me a lot of pleasure over the past 2 years. I thoroughly enjoy mixing pickups, trying new wiring options, in an endless search for tone.
I am trying to set up a different amplification path at present using 2 Bi-amped Active Speakers, and a music Processor, (Lexicon Reverb/Echo plus), instead of the usual guitar valve amp etc.
Not interested in connecting up a PC, but simply to find new spatial tones, and use this as my main guitar setup.
I would very much like to hear from anyone who has gone down this route or has any advice as to what else I might need to complete the package, such as a Mixer, or pre-amp?
I used a cheap Zoom 505 about 8 years ago, with a pair of clapped out 50 watt active speakers, just that, and, ignoring the background noise the speakers were adding to the result, the sound was pretty impressive- Very Spacey, toppy , but with a lot of presence and clarity. (60's Spotnicks).
Any thoughts? Regards, arthur.
