The most cedar-like of all the spruces, Engelmann is often used for fingerstyle guitars where responsiveness to a softer attack and a short period of opening up is desired. But in pairing it with bright, beautifully figured koa on their jumbo-inspired MG, McPherson have proven that this tonewood is capable of plenty more. McPherson have applied their unique, patented build techniques to absolutely maximize every bit of sonic potential these tonewoods can have. Their proprietary offset soundhole, cantilevered neck, and unusual over and underpass bracing system all combine to maximize the vibration of the soundboard. Thanks to some graceful curves, this large-bodied, 4-1/2" deep guitar sits very comfortably in the lap. 

Like all our new McPhersons, this MG 4.5 comes with some major player upgrades to complete the package: EVO gold fretwire, a pre-installed L.R. Baggs pickup, and custom Ameritage hard case.
