Reverb signal view on oscilloscope

[mopar39]

I'm a advanced beginner (oxymoron?) and was wondering what the oscilloscope trace should look like if I put a low volt sine wave through my tube amp.

Good question. I wonder too.

A lot depends on how you trigger the scope and whether you're using a digital scope or an analog scope. For an analog scope if you trigger on the clean sinewave that you put into the amp, I would expect to see a clean sinewave that's in sync with the input signal. And I would also expect to see several out of sync sinewaves that appear to just be free running across the display.

A digital scope would probably just show several sinewaves.

Of course I'm just guessing. I've never looked at the reverb signal with a sinewave signal source. Why don't you try it and post a pic.

I will in the next couple days.  Thank You!

nope, me either

should look like if I put a low volt sine wave through my tube amp.

now that i've done and posted results

I've only ever looked at reverb on a phasemeter, which is a scope set up for X-Y display of the Left & Right channels of a mix buss.  With that, you see the reverb imparts a bunch of delays of various times, at somewhat lower level than the original sound (depending on your reverb settings, of course).

I don't think a steady sine is a great signal for observing anything about reverb, just as one held note on the guitar doesn't really let you hear the reverb effect.  A short impulse gives much more information, and might make the reverb trails easier to see on the scope.
