Does the K&K need a nearby preamp? I had a microvox (I think)small fag tip size mic which gave good sound but the short lead to a preamp was a dead loss. Albeit small the preamp would fall off the belt or wherever and tug the mic off the guitar. I lent mine to someone, forget who, and never got it back but didn't worry.

As others report an anmplified acoustic guitar always does sound a bit 'electric'.
