My heartfelt 5 cents, to achieve your goal (last point is probably the most important):
1. Get a decent pair of monitors (studio monitors or floor wedges / doesn't have to be super expensive.. drum amps (like the CoolMusic DM100) are great ""FRFR"" monitors for modelers)
2. Get a Line6 modeler (HX Stomp recommended, if not, Line6 Pod Express or even Line6 POD GO) <These also double as audio interface for you to record / reamp)
3. Set atleast 3 tones up to your liking: (Don't overthink or spend too much time on this, just spend 10 mins, dial in and GO)
i. Clean (of any flavour you like, compressed clean or clean /w mod (chorus/phaser etc.))
ii. Crunch (for rhythm playing.. with mids slightly scooped out, so it doesnt crowd the mix)
iii. Lead (with lots of mids, to stand-out and sing)
4. Find 5 songs / parts you want to nail. Get a notebook, a metronome app and start logging your practice everyday.
5. Don't log back into TGF or TOP for ATLEAST 3 months (the longer, the better); instead, focus on #4.
All the best!
