I'm totally new to recording! Soon I'd like to set up a youtube channel doing covers of songs on piano, electric and acoustic guitar. A few months ago I bought a Shure Sm57 cheaply off Amazon, at first it didn't work so my dad unscrewed it and the wires weren't soldered. He soldered them, but when I used it to record my upright piano, even when I put it right next to the soundboard it was extremely low output. I had it plugged into my old dell laptop running audacity, and by the time I had amplified it enough there was an awful lot of hum. Was it likely that this was a fake? Now, I want to get another mic for recording my upright piano, I've done a bit of research and it seems that condensers seem to be best for this sort of thing, what model(s) do you suggest? £100 is my budget but I could maybe go slightly over if I'm going to get a much higher quality one. Also, do I need an audio interface? With my Sm57 I plugged straight into my computer's 3.5mm jack socket. Also, this might be a really stupid question, but obviously condenser mics need phantom power, can you get an audio interface with phantom power? Thanks very much in advance for all your help.
