The KOA Effect





 

Yamaha And The KOA Effect
 
 
Introducing the A4K and AC4K guitars, expertly crafted from all-solid, Hawaiian koa! These limited edition acoustic-electric guitars are a fine addition to the highly-acclaimed A Series lineup.
 
 
 

 

The A4K dreadnought and AC4K concert-size A Series guitars both feature cutaway body designs, double-line abalone inlays and unique black tuning machine keys combined with the SRT (Studio Response Technology) preamp system which delivers a natural, acoustic miked sound.
