I am looking to record acoustic guitar. A lot of folk and finger picking so low volume playing. Based on what I have read so far I am in the market for Small Diaphragm Condenser(s). I am looking to spend somewhere around 500 CDN but am flexible. I currently am using a Sm58 (without the windscreen) into a Scarlett 2i4 and am recording in an untreated room. ( The room is carpeted, free from exterior noise, and I am using some cheap duvets/packing blankets placed behind me as I record to reduce reflections. ) I am close mic-ing my guitar around 12-14th fret with the 58 and I am finding that I am lacking high end clarity and brightness that I believe a SDC would better capture. I have read multiple reviews on recording acoustic guitar with stereo pairs in stereo and an equal amount preaching that acoustic guitar should be recorded in mono and double tracked if necessary in order to achieve a stereo mix. In my untreated room and with no almost no recording experience would I be better off taking the mono approach? (I have been producing electronic music for a few years now and have Ok mixing skills and have been able to get some results I am happy with so far just with my mono 58 set up, some doubling and stereo reverb.) My question is then: for my limited price range would I be best going for a single SDC or matched pair? At the top end of my price range that would be comparing say: Rode Nt5-MP (579 $) to a AKG C451B (531 $) / AT4022 (469 $) [Slightly out of my price range is the AT4041SP (649 $) which I have seen recommended] but also on my mind is that in an untreated room and within this price range would any of the above options yield significant better results then say: Rode M5-MP (269 $) / Samson C02-pair (189 $) to a Sontronics STC-1 (245 $) / AKG Perception 170 (127$) /AT2021 (109 $) I realize I am comparing mics double in price but I am just wondering if the extra cost would be worth it? And when comparing SPs to a single mic my thoughts are: might as well save 50% or conversely get a single mic that's twice as good for the same price and record in mono. I realize this is a lot of information but I would seriously appreciate any insight and recommendations!
