Your general opinion of this product.
An inexpensive device to enhance tone and control feedback.
Seems to do the job.
After installing it in my Fender Kingman bass I noticed more bottom end and so far no feedback.
Not hard to install. I did have to drill a hole to allow for truss rod adjustment.
Made of flexible plastic. After installation the only hint that it's there is a small black retainer ring around the soundhole.
So far so good.

Provides a Positive Upgrade, BUT
Yes but they need to acknowledge the need to modify it for pickup controls.
Fine- flexible plastic- seems reliable,
Your general opinion of this product.
The concept is sound
Does not affect action , etc.
More focussed sound- I think it affected my drednaught more than my OM.
Relates to installation- if you have sound hole controls you ahve to cut slots to fit. There are no punch outs or templates provided. I used a sharp utilty knife, diagonal cutters and a self made wood support to assist. The material does cut easy. You may also have to drill a hole or cut a slot to access the truss rod nut.

Subject: Sounds like a good idea
Discussion: out of the box it won't work for my primary acoustic. I'll probably buy one of these to use with my dreadnaught which has an active pickup installed. For my primary acoustic though, a little parlor guitar, I use a woodie pickup. If there were another model built to accommodate a soundhole pickup like that it would be ideal. I guess after I hold one in my hands I'll see if I can modify one for that application. Kudos on the concept though. Simplicity and common sense applied. Makes you wonder why someone hasn't already built an acoustic with a projection flange integrated in the design.
