Bama, If you're still around....
I just noticed a thread asking about some Perreaux stuff, an Amp, Preamp and the TC (short for tone controls). I put this in my SP10 in the 80's to do just what you are trying to do. Its really transparent and will work well in your pre-amp tape loop. It has 3 tone control, low medium, and high. It also has high and low filters, a defeat switch and a headphone amp. It was intended to be used in-line between amp and pre-amp and works well there. If you are interested let the guy know. I suspect its worth about $150 +/-. Cost about $350 new. Contact the guy if you're interested.
FWIW :-)
