I have a Belle Epoch and it is just awesome. I tend to run the preamp in the Belle Epoch at about half way to give the front of the amp a bit of a hit. I have read nothing but rave reviews in regard to the Chase Tone Secret Preamp and as G.A.S. would have it, I am intrigued. I would the imagine the Chase Tone is a step up from the Belle Epoch circuit and if so, would simply turning off the Belle Epoch preamp and using the Chase Tone only be the best move to make? Is anybody using both in tandem?
