The Belle Epoch is wonderful. I got it for long spacey delays, but now have it set for a slap back. It sits in the mix so well; very warm. Love it. The Flint is a new addition. Again the tremolo just sits well in the mix - by mix I mean guitar and amp mix. It sounds natural and I am playing through a deluxe Reverb made by Roy Blankenship. The Flint is great so far. I am still warming up to the reverbs.
