I'm thinking about upgrading my mic collection and with it my pre amps. Right now I have an Audio Technica AT 3035 and a presonus tube pre with 2 inputs. They have both gotten me plenty of decent recording but I'm now looking to upgrade. I've been doing a lot of research and I feel pretty dead set on getting the A-designs P-1 pre amp and the AT4050 mic. I use Mbox 2 and protools. Does anyone see a problem with either of these investments, seeing as I'm doing mostly personal acoustic recordings.
