I've been toying with getting a tremolo pedal for a while, mostly for rootsy, bluesy type wobble, wobble, wobble noises, and there are quite a few that had piqued my interest. To cut a long story short I ended up paying just shy of fifty quid for a Mooer Trelicopter. As well as being fairly cheap and sounding (to my ears) very good for the money it's also tiny, as you can see from the attached photo, so it nestles nicely on my pedal board without having to move anything, which is a plus.
I haven't tried any of their other pedals, but for the money, they seem really pretty decent. Happy so far. I'm now off to go and pretend to be Ry Cooder, only much more rubbish.
