But are ovations really acoustics?
a·cous·tic gui·tar
noun
- a guitar that does not require electrical amplification, having a hollow body that amplifies the vibrations of the strings.
All guitars are acoustic guitars. Even plastic ones.
Soundboard is made of wood.
There were two layers of fiberglass cloth that had a perscribed amount of resign poured on it in a heated press
And it was called lyrachord
And in 1974 there was the coming of the applause. And its bowl was made in a compression heated mould from a mixture of polyester resign and chopped glass fibres
And it was called SMC
but the New hartford Ovations stayed with the cloth
In 1982 there was an experiment of making guitars in North Carolina and all the bowls were made there from the SMC
And in 1985 the experiment ended and all the bowls went to Astabula Ohio. Reifnements were made in the material
And it was called HMC
And that's where it is today
Now as a further note the cloth bowls were about 35%glass when all was said and done. The SMC(sheet molding compound)is a layer of resign that looks like taffy and had 1" chopped fibers inbedded in it. Those bowls are also about 35% glass. The HMC is made with fibers 1.5" long and are also the same percentage. We found that the longer fibers sounded better, more like the cloth bowls that were a PITA to make. Material costs werren't a real factor but mfg and scrap rates were. HMC was better on both.
There was a phase over from cloth the SMC/HMC. The Adamas 2 were all SMC from the beginning. the Adamas 1 was the last to switch from cloth.
All things being equal the cloth probably sounds better. But things are never equal are they? The finish, top thickness, grain, brace patterns, neck material, how it's joined to the bowl, type of rosette, bridge material all affect the sound.
So Sam I've heard cloth bowls that were last in the bow-wow 500 and HMCs that were in the top 10.
There you have it.
