If you guys want something like this: https://www.metronomeonline.com/ I think I can do something like this fairly trivially. I don't know much about what a metronome needs to do but I imagine if the site above is what you want it'd take me like idk 5-10 hours to make something I'd say. So hundreds I'd say! Maybe a thousand at most, unless I am missing something here.
The amp & pedal idea sounds like an amazing idea! The metronome definitely isn’t a “must” but just for convenience. Maybe in the meantime, you guys can even embed a metronome from another source on the site until you have one finished or something.
I figured there’s tons of stuff in the works that we don’t know about, based on the idea I texted you a few weeks ago!
