The boss fv500 is well worth a good look.
No tone issues, adjustable tension, and a minimum volume pot on the side, so you could easily set it up for swells etc.
It also has a socket for use as an exp pedal. I have had one now for about 6 years with absolutely no issues.
They can be found for about £70 new and probably £50 ish secondhand- although I notice they don't come up for sale as often as the ernie.
I'm not knocking the eb, I just think its overpriced
