Adapting an acoustic bass

Sign in to disble this ad
I have a semi-acoustic bass guitar that I originally bought for BBQs, picnics etc. The electric capabilities were just a bonus, as I have an electric 5-string that I use most of the time.
Trouble is, like most people are aware, it isnt as loud as I wanted. When the guitars are hammering away, I virtually get drowned out.
I was just thinking, if you were to make the hole in the body a little larger, would that allow more sound too escape, making it louder? Ive had a look, and I figure I could possibly cut another 5-6mm from the original hole without it being a drama provided I start either side if the base of the neck.
Please, if you have any ideas or opinions, constructive opinions, dont be shy!

No, it doesn't work that way. Sound holes are for resonance, and tweaking it will change the timbre of the instrument and the frequency curve, but by no means will it "make it louder" with any definitive answer.

but by changing the frequency curve could`t you make that the lower frequency resonate more? i know that if you put the hole in a diferent place you get diferent frequency response but i dont know many about it

PS sorry for my english

Yeah, it's potentially possible, but you don't do it by haphazardly making holes. There has to be some science involved in it. (Or experience.)

You would need a bigger body to make the sound noticabley louder. You could always remove the back off the body then attach a second ABG body to it, lol...

Do some research on the term: Pignose.

Portable amps, battery-powered.

What you are experiencing is the physical phenomena that is plucking 1 string against struming 6 strings! Your only hope is an upright or if you can get your hands on an Ernie Ball Earthwood AEB to do what you want to do without amplification...

I gotta better idea. Get an upright bass. They blend real well with multiple acoustic guitars. That's why all the old folk/bluegrass bands use 'em.

Of course, they're stinkin' expensive. And you have to basically learn a new instrument. There's that...

Nothing wrong with learning a new instrument.
