Supro SF2/SFS2 Footswitch

It's simple and it does the job. Feels like a quality made product. It's basically a 5* product. But a half star down only because the switch clicks very loudly (it is quite audible!). Another half star down because it really should be included with the amp that features these two functions (tremolo and reverb), like Amulet for instance.
The ''lack of'' LED lights is really not a problem, you hear when it's on or off right, right.
So essentialy it is indispensable part.
