Recording my music?

Depends on the quality you want and whether that guitar is Acoustic or Electric. The most important thing for starters is a "Clean" signal. A tape recorder is not going to allow you to get a non-distorted clean signal. Nowadays people are using their smart phone recording feature. There are even apps that have music recording features for the Novice up to the Expert musical recording enthusiast to put your Masterpiece on wax as they say in the industry. Some apps are free for a Trial period. For dollars you can buy a condenser mic for apple or android on any of the online stores that sell them and achieve an excellent signal for acoustic guitar. You want to capture the wood, the strings, the room ambience, the fret sounds, and render that natural earth tone sound with acoustic. This is how you do it. For electric you can buy a small signal processor that input right into your android or apple phone that records your electric and even some acoustic sounds right into your phone with a clear signal and professional sounding results. Many of the effects guitarists are seeking are even included. The cheapest one I found was about 8 dollars on Amazon. I would not be suprised if you could not find them cheaper. So, to answer your question, being the musician I am, I would buy the IRig or a condenser Mic for electric or acoustic guitar. Those items will give you the best quality and simplicity with a grand total depending on which guitar you are looking to record of $16 dollars and $8 dollars, respectively give or take postage and handling if you order it online. Some places may even ship it for free. Hope this helps.

Go to a thrift shop and fine a tape recorder. Use it. Get the song together, all the instruments and all, the vocals and all that. It's not going to be that good as going to a studio where they could knock out imperfections. Or a cheaper way to pay for the studio, go put on a lot of shows, save up the money from the profit and use that to rent a studio.

Use a standard home casette recorder, or a 4-track. For better quality, go with the latter. Don't expect digital-quality sound if you go with the 4-track. You don't have the editing feature on there, as you would with a digital mixer, such as the one I use when I record at church--Cubase. With Cubase, you can record a sermon, or music, right on the computer, using the board mixer. I prefer the four-track because I am in love with the vintage 60s-early 70s, hollowed out sound, like you are in a stadium or something. The drawback is that if I were to make a mistake on my vocal track, I would have to start over and resing everything. Or if I were to make a mistake on my rhythm guitar track, I would have to re-record that. That would give me a particular headache if I happened to be doing a lead guitar track, and somehow that went bad. By the way, I really do prefer using my own recording tools. It saves money, and you can make your own music the way you want, instead of a producer telling you how he would want it done. That is giving someone else too much artistic control. You are actually working for them.
