Hit 1,000 hours on my oscilloscope and it finally clicked

I picked up a cheap used oscilloscope about 2 years ago mostly to mess with guitar pedal builds. Last week I hit exactly 1,000 hours of use on it according to the counter. That number surprised me because I never thought I'd use it that much. At first I just looked at sine waves and didn't really get what I was doing. But after the first 200 hours I started catching noise issues in my pedal circuits that I'd missed before. By 800 hours I was using it to diagnose a failing power supply in an old amp I fixed for a buddy. Now I'm wondering if there's a tipping point where a tool like this stops being a novelty and becomes essential. Has anyone else noticed a specific hour count where a piece of gear just started making sense to you?

2 years in and I still don't see the big deal with oscilloscopes honestly. I built guitar pedals for years with just a multimeter and my ears, never needed a screen full of squiggly lines. To me a scope is just a fancy decoration that collects dust once the novelty wears off. If you can't find a noise problem by listening or swapping parts, staring at a trace probably won't fix it either. Tools like that make people overthink simple circuits they'd have solved faster with basic troubleshooting.

Same here, I never touch mine unless something's visibly broken.

Has anyone here actually tried using one for audio restoration work, not just building stuff? I had an old tape recorder that had this weird flutter issue no amount of listening or part swapping could find. Hooked up a cheap scope and saw the motor control line had a 60hz ripple that matched the tape speed wobble exactly. Fixed it with a simple cap filter in ten minutes. Sometimes you need to see what you can't hear, especially with power supply noise or clock signals that mask themselves as something else entirely.
