Jim Dunlop System 65 Body & Fingerboard Cleaning Kit (6503)

Don't use any app to tune. Get yourself an actual tuner. They're super cheap.This is my recommendation. This thing is great, the biggest downside with tuners like these is the weird little coin sized battery that needs replaced from time to time. This thing is USB rechargeable. I just simply charge it once or twice a year and it lasts a good 6 months or so and I use it a little bit everyday so that tells you how long it lasts on a single charge. You can clip it right to your headstock. Mine never leaves my Guitar. I would not recommend cheaper tuners like snark. They have a history of snapping easily and breaking. They aren't as accurate either. Daddario has a couple good tuners with different sizes. They have a micro one too if that's more your preference but use a real tuner, not some goofy app. I know a lot of the kids find those popular convenient and easy but it's also convenient and easy if your tuner is literally on your headstock at all times ready to go. Here's what my head stock looks like. I keep my guitar tuned down to half step at all times because a lot of great songs I love from the '90s that I grew up on are in that tuning and I almost always practice by playing along with the actual album. I have a giant playlist with every song I've learned and I just put it on shuffle and start playing along with the band. I play all my standard tuning songs with capo on the first fret to bring it up to standard, obviously many songs use a capo various places anyway. Everything I need for a long Rock session is on that headstock. You should probably learn how to restring your guitar as well. If it's a hand-me-down guitar chances are those strings are very very old. It will sound much much better if you get some new strings. Your local music shop will be able to help you out. Personally I prefer 80/20 but a lot of people also use phosphor bronze. If you want to sing while playing you should probably go with 80/20 instead of phosphor bronze but that's up to you. You can look up videos about the sound difference between the two and decide from there. Here's a great video that will teach you the correct way to restring your guitar. Do not use a knot. watch this to learn the correct way to restring your guitar. Here's a great video explaining the difference between 80/20 and phosphor bronze strings. personally I lean heavily towards 80/20. Maybe if you're playing a loud lead you might want phosphor bronze for recording because it cuts through and is louder but 80/20 has that sweet spot dip in the mid-range where it's perfect for a voice singing along with it. If you're a singer-songwriter type you'll definitely want 80/20 instead. Since you're new you'll need a peg winder/string cutter like this as well. And if you care about the instrument at all you definitely want some goodpolish and fretboard conditioner. Lemon oil works fine.. I only do this about once every few months when I restring it. It gets dusty and dirty, take a few minutes and polish the fretboard. It makes an incredible difference and you'll be so happy with how great it looks every time you clean that fretboard. It does make a world of difference. Take care of the instrument. Not to give you a shopping list and rack up a big bill but all of these things are fairly cheap. Get them as needed I guess. Start with the tuner, maybe a capo, later the strings, cleaner etc. If you get into it you'll end up with all of this anyway.
