This is my first dog bowl guitar and I plugged it in. In this cbg Good idea or not I used a springs around the bowl and on the bottom spacer I hollowed that out and stuck on spring, My question is, if your making a electric cbg, should it have sound holes, just asking respectfully…..Show you some pictures of my first dog bowl which I need to a strap buttons and bring down some strings on the nut end and burn dot markers, it’s bad…your bad….stay cool…
Hi, Nice looking CBG Howard. If you are not using the guitar acoustically you can go without soundholes.
If using a magnetic pickup they sense the vibrations of the strings, so the body can be solid, or hollow with no soundholes, you will get good output.
If using a piezo transducer, meant to amplify acoustic sound, they react to the timber vibration, or whatever they are attached to. They will also work in a body with no soundholes.
However, if a good acoustic-only sound is sought then soundholes release the soundwaves and other frequencies that would be trapped in the body.
Hope this helps.
Thank you Taffy Evans for your comments, do you think on a dog bowl with a piezo pick up under the bowl, sound holes are needed, just asking respectfully, thanks
Thank you Taffy Evans for your response. On my first cbg, I put black window screen to cover my sound holes, but later removed it thinking it would restrict some sound, on this cbg, I covered the holes with metal, but have a piezo pick up under the bowl, sounds good when plugged in. Thank for your response…
Hi, I understand that 30% of the sound we hear comes from out of the sound hole. If playing acoustically, unplugged, with no soundhole you are potentially missing 30% of the sound that is generated by the strings.
That's assuming that the box or guitar is constructed in a way that produces a decent acoustic sound to start with.
A piezo pickup's output, when used, would override any natural acoustic sound from the instrument's soundholes, so I feel soundholes in that case are not needed.
Soundholes in instruments are a big subject, far more involved than the simple instruments we focus on here. The best way to learn, I think, is to try it for yourself as we all build differently and get different results. So what I suggest for my builds may not work for you.
Good luck Taff
