I recently purchased a Blue "Bluebird" mic for about $300.00 and it does a great job on recording fiddles and banjos into my Tascam Neo2488, but I have a really nice old Martin 00-28 and I'll be darned I can't find the sweet spot for recording this guitar. I've tried it at the 14th fret about 12" away and even over the bridge about 24" away along with several other positions. No luck. Once I go ahead and record, I can add mid and highs in the mixer and get the guitar sound acceptable but not until. I intend to purchase a mic pre eventually. Any ideas in the meantime? Thanks in advance.
