Recording engineers and musicians sometimes have strange sound ideas. Well, experimenting with sounds is fine and desirable. Once you start to do that, you’ll never know what you will get. However, you should always save the audio source on another track as neutral as possible. Just in case.
One of the hardest things to correct in a mix is human voice recorded with a bad microphone. That’s why you should always do all the sound experimenting safely to another track keeping the original, neutral sound too. A decent vocal track may be recorded with a low-cost microphone, though in lower price range there are also bad microphones available. If you are not sure about vocal mics, ask someone who knows better.
Generally, you should record your tracks as dry as possible and if you want to record the room, record it to the other tracks. For example, it is usually worthwhile in drum recordings to capture the sound of the recording room too. It gives you a natural reverb, that can be further processed – if necessary.
When recording a bass track, it is a good idea to use di-box. If you want to use an amplifier or an effect, you can record those on their own tracks or use plug-ins afterwards.
So, keep in mind these words: neutral and dry, and you can´t get it wrong. Of course you have to choose the best mic that you have available for a specific track.
