Question about Focusrite Scarlett solo 3rd gene

Yes, but note that there is a limit in the number of tracks that can be recorded simultaneously. I think the limit is one line level (pre-amped) and one at INST level (e.g. mic or guitar).

If you wanted to record more than that you'd need the 2i2 or 4i4 etc. I would suggest buying the 4i4 or higher anyway because that will future proof you in case you want to record yourself, e.g. in a band and be able to manipulate the tracks individually in a DAW.
