Hi there,
I'd have to agree with.. um.. gtoledo3.
The Sytek is a great unit, for what it is. Inexpensive, solid pres. I have a friend that uses them on classical guitar over the Amek 9098's he has in the rack.
If it were me, I'd go with something that had a little more character for my second unit. If you know a good tech, and you know what to look for, and you look real hard, you could get a couple raw V72's (Siemens/TAB/Telefunken) for about $1,100.
They are something special.
That being said, you may just want to save yourself the headach and get racked ones.. or the TAB Funkenwerk. Oliver Archut is basically the man with this stuff. Damn nice guy to boot.
