i decided i have a little xmas money still around and i want to put a new pre-amp in my spector..probably. I was thinkin maybe a U-retro, but then i saw the price and that i'd have to route a few more switches in there. What would be a good 2 band pre-amp for my spector?? I have about $150 to spend on it. Does anyone have any they want to sell or good ideas for it? Thanks for the info in advance.
