to my mind a really well set up cheap guitar often sounds better than a poorly set up £2000 guitar.
It never ceaes to amaze me how many guitar shops sell expensive guitars and refuse to include a proper set up. Factory set ups are generally not much cop. Getting the action, intonation, neck relief, fret dress etc spot on is key.Once done don't go changing your string guage when you fit new strings..stick to the guage (and brand) that the guitar was set up for...so make that decision before you pay for a set up! My suggestion would be to avoid the temptation to fit light guage strings like 0.08's...they only last ten minutes and play like elastic bands..go for a standard guage to start with at least..0.09's or 0.10's. Old rusty dead strings will bugger up you intonation and sound BAD. Buy a job lot of strings from an online provider (cheaper) and change them as needed making sure you stretch them in properly.
Playing a badly set up guitar as a beginner who knows no different is one of the reasons why many beginners give up, blaming themselves often instead of a poor instrument. If you are serious about learning then get your guitar set up properly.
Getting your ideal tone is often a lifelong quest for many. It is important that you have a playable tone. To many beginners are sold cheap rubbish transistor practice amps as part of a 'beginners package deal'. They sound and play HORRID and can easily in my opinion put people off as they fail to get the tone they want. Ideally a full tube head with a cabinet loaded with celestion vintage 30's or greenbacks (expensive)...is a good guide. Failing that and if you want to play at bedroom level (which I do most of the time) get a simple line 6 pod amp sim...dirt cheap on
Ebay. Ok it's not valves but it sounds superb for the money if you tweak it right...and it doesnt piss off the neighbours!
Endless FX etc are fun but don't be foole dinto thinking they are what makes your tone in isolation. The single biggest factor in your tone is your fingers, your mind and in my case anyway, choice of plectrum. Even after 35 years of this I still practice 80% of the time with the guitar not plugged into anything.
Above all dont run before you can walk. Get the basic foundations in place. Simple chords, basic scales, synchronization between right and left hands, timing.
