believe me, you don't need to spend that much on one to get a good acoustic sound.
actually yung acoustic "plugged" sound dito, as we know it (because of the rise of acoustic bands) medyo generic, kahit ano pang gitara gamit nila. i'd like to call it the "piezo tone" hehe. kasi most of the pickups available here, or the acoustic guitars na available dito puro equipped with piezo pickups. which is, i think sa ngayon, the cheapest way to amplify the acoustic guitar. so since yung technology ng under-saddle transducers or piezo pickups ay basically pare-pareho lang, yung sound na napoproduce nya, parepareho lang din, any guitar with a piezo pickup ganon din tunog, mapa-oka smid man yan or ibanez or yamaha or even fernando, parepareho lang. nagkakatalo lang sa preamp and shempre, ang mixing ability nung gitarista. so kung balak mo naman i-plug ang acoustic mo, no need to spend too much on expensive branded guitars. well, unless yun talaga yung thing mo, acoustic guitars.
for a really true acoustic tone, nothing beats the old-fashioned mic over the soundhole. ganon parin sila sa recordings eh, miked parin lahat. dun mo maririnig talaga yung character nung woods used, yung picking style nung gitarista, and the resonance of the wood.
