Title: Cheap Digital Oscilloscope
Post by: BetterOffShred on March 29, 2017, 11:40:38 am

Hey there, I was just wondering if anyone had any experience with cheap devices like this:

and if they would care to comment on it.   It looks decent for $25, but I honestly don't even know what I'd be looking for in functionality for use in guitar amps/pedals troubleshooting as far as features go.    Anyway, thanks for looking!

Cute. I've had good use from 'scopes of lesser specs.

The photos are not inspiring. Bent pin? Crooked display? I hope they take more care assembling them than they did spiffing it up for beauty shots.

Nevertheless, I approve you spending $27 to try it. <G>

I've actually read those are pretty horrific in signal quality/integrity.  I think it was EEVBlog or maybe Julian Ilett that did a review and called them absolute crap.
