Do I need a preamp for recording my synth?
Short answer- ‘need’ is a strong word, but your synth tracks would certainly benefit greatly from a preamp. Simply put, adding a preamp to your synth lines will make them come through a little stronger and have more impact on the mix. Any preamp, whether they be solid state or tube are designed to make your signal louder.
We have done some A/B testing with one of our favorite analog synths, the Korg Minilogue, and found that a preamp or external tube amp helps the synth to stand out. It goes without saying that you will be using a wide range of synth voices so where and when a preamp adds the most will vary.
