It's not about the equipment. How good or how much you have. In the end it's what you want to sound like. What is important to use to get what you want in your music. As a beginner I'd say stick with the basics. You already have a computer. For recording get a basic DAW setup ( digital audio workstation, a fancy wording for recording software,) and a USB microphone. You wont need a lot of expensive equipment to start learning how all this stuff works. However a word to the wise. Not all USB microphones are good. You get what you pay for. Some are no better than the built in mics on your laptop. Your better off not buying a cheap mic.
As far as loopers go a TC Electronics 'Ditto' can be had for around $80 on Ebay. Or under 50 if you catch a good deal.
As far as effects go the market is flooded with them. There are a few tried and true distortion boxes out there.
Ibanez Tube Screamer,
Boss DS-1 Distortion,
Go to Youtube and check both of these out. They have different sounds. And will sound different with a piezo pickup.
My advice? If you just started playing then go with what would be the most fun. A distortion pedal. You can still record yourself using the equipment you have.
Do not get sucked into buying effects and all sorts of other gear. Just buy an amp and a lead. The Roland MicroCube is a great starting point, but any of the Roland Cube range offer a great range of tones from clean to heavily distorted overdrive, plus some easily useable built-in effects.
The worst thing about effects for beginners is that they can be flattering to your guitar sound, and fool you think you are sound like a much a better player than you are, You can spend a lot of money, time and effort making noise rather than music.
Dani,Bear,from a 'not very good player',C B John's advice is sound,i have a couple of pedals and a looper,they're buried in a drawer,i found they just added complexity to the basics,i've had a bit of fun with the looper,but my playing skills don't justify fiddling with it,i have a reasonable amp with more effects than i can justify,[orange ldx 20],i have around 17 guitars within easy reach,and i rarely turn my amplifiers on,1 step at a time for me,i generally amplify my fretless guitars only as i can fudge a bit there
Really any decent multi fx practice amp will give you tons of options. Line 6, Vox, Roland are probably the best of them, and the Peavey Vypyr if you're going to play more than guitar through it. Tons of them on the used market and very reasonably priced; between $40-100. Sometime on the $100 end you get a cheap Strat bundled with it.
If you just want a single track of looping, using something free like Audacity and your computer is easy enough to wait until you need a looping pedal. I play bad washboard or suitcase bass drum onto the computer and play along with it best I can, definitely adds to playing at times!
