Product Review

I have always bought second hand when it came to music equipment. Convinced that Lenon was right in saying, “give me a tuba and i’lll get you something out of it”. While that is true and, every young musician should live by that, there is also plenty to learn and benefit from nice equipment. Now, don’t get it twisted. I am not saying a $10,000 guitar will make you sound like Hendrix or that an equally expensive microphone will bring the heavens down when you sing into it. But, if you want to, at the very least, put out your honest sound; then it really does pay off not skimping on recording equipment. No mic will make you a better singer but cheap mics will not do you any favors either. The Blue Baby Bottle (cute name) will give you a true/professional sound for a reasonable price. Go through the gamut boys and girls while you are still finding your sound but when you are ready to give it to the people then spend a lil scratch investing in this microphone.
