Just having a vertical dual switch is a serious space saver for your pedal board, & that alone makes this a worthy purchase, & like the title says, you don't have many other choices. The build quality is exactly what you'd expect from Boss (stellar) & since it's a simple dual switch, it functions as it should, although I am having an issue with the Boss OD-200 not switching patches both forward and backwards, using the A/B switches synonymously, but I suspect that's from not doing a firmware update, suggested when you get the pedal. So why the 3 stars then? To be fair to Boss, it should probably be 3.5, but there are no half values, & I wanted to be sure this review stuck out. I expect there aren't many reviews lower than 4, which is in itself a positive review of the FS-7. It's not because I'm a narcissist, but because you should know what to expect from the feel of the switches. I expected each switch to engage independently, w/ a clean click, giving your foot some tactical feedback, which is immensely important on a loud stage, possibly soaked in overhead light, leaving led indicators useless, or on any stage, for people with vision problems. That is NOT what you're getting here, & instead it's a switch type that's silent, & completely passive. I'm not sure, the exact name of the switch type, but imagine of you take a ribbon of steel & just make a loop out of it, that's oblong, kinda like the outline of a hotdog. Now push in one sides until it makes contact with the other, & that's your switch. I believe the actual switch in the FS-7 is a ribbon of steel that's bent up at a 45 degree angle on each end, that you push down until it makes contact w/ the base when fully flattened, if that's easier to visualize. Either way, it's not a good feel IMO &There are some horizontal switches that can work just as well when flipped vertically, so if tactical feed back is something that is a must have for your situation, then I'd consider going that route instead.
