Does something like this suffice for a guitar amp hobbyist?
Thank You

Don't forget smartphone apps. Free if you already own the phone.

I have something similar, built from a Vectronics kit. It'll do about 11V p-p, and works fine for my purposes.

I used to use Audacity. It's free. It will generate tones that you can play via your computer or burn into an audio CD.

Now I use my Jam Man looper pedal with tones generated from Audacity.

I have loaded appropriate tones (10hZ, 100hZ, 1K, 10K) onto my iPod, and plug the iPod into the front of the amp under test. I generated the tones with a demo application that I downloaded off the web, and saved the tones as mp3 files.

While there must be hundreds by now, apps and PC snippets that'll do a lot more than plain jane test tones, that kit should do just fine.

I'll put in another vote for Audacity...

I did not want to plug in anything valuable (or AC driven) in case of ground differences or possible voltages present (on a brand new build), so I record the tone on a CD and used an old dollar store CD player that was laying around.

I am amazed at how stable the signal is. If it takes more than an hour to scope signals, just restart the CD.

Cheap and quick.

I also set up an old abandoned digital camera to take scope pictures and upload them to PC for printing and recording the voltages...
