Hi all. Just picked up a new amp. An SC400. I had a Studio 110 for years as my practice amp, sold it when I decided I would never have the opportunity to play in a band. And what happens? I get invited to play in a band. I run my PRS CE22 & MC58 into my Boss GT-100. I would run that through a small sound board for practice. Well now the band I'm joining wants me to have an amp. I found a clean 1988 SC400 with footswitch. All works as it should and only cost me $125. (Good deal?) My musical tastes run from modern country, acoustic rock, classic rock, and some modern rock. No metal. Should I run it thru the front or thru the preamp IN in back? Also what settings would be best to keep the amp transparent and let my Boss do its thing? FYI, the Boss has an output setting for a JC120, should I use that or leave it in LINE OUT output? Any other suggestions or advice would be appreciated.
