I have tried to save money on demo recording. I bought a Roland 2480 to record demos. It is a fantastic recording all in one studio. The learning curve is steep. I have learned alot but I have so much more to learn. I  don't want to be a recording engineer. I don't enjoy the recording process. I have tried recording myself playing guitar, singing, playing the bass, mandolin, and sometimes the harmonica. I have been less than impressed. On my last three songs that I did a demo on. I had a friend of mine who is a great singer come over and sing. His name is Jerry Abbott. This was a step up from my previous recording. My friend , Ken and I co-wrote a song together. He took it to a professional studio an had it recorded. He found a singer and the owner of the studio is a great musician and plays many different instruments. Wow! It turned out great. The thing to remember is that  a great sounding demo does not necessarily make a great song. The song has to be great in the first place. It sure does sound cool. It is great to hear you song when it has been professionally done. It adds a little polish, kinda like a good polish job on your old car. It might not be a new car but it sure shines like one. Same with the demo. It might not be a hit song, but it sure shines like one. Ha! Ha! Jim
