I think you'll find they sound more like an acoustic up right bass. Or at least that's my perception having recorded a few. A direct input & a microphone on the Cabinet makes for a lovely sound and I am generally not one of those people to put microphones on the base cabinet. Quite a nice sound.

Acoustic electric bass, for those too lazy to schlep the real deal.

I have recorded a Few. Like ACU GTR some have more low engery then others. We used ACU bass on a techno song to try and give the tune a bit more reality. I liked the sound we got. A lot of string sound but still a punch around 150hz. IT was mic'd with a Rode NT2 on the 12th fret and a AKG C3000 behind the bridge.

not to distract too much, but sometime i'd love to see and hear a fretless acoustic bass. i bet it sounds sexy!

You can't beat the nice "growl" of a straight-up acoustic bass. A sound unto itself. The hardest part I've run across in recording them?? That's easy - finding a bass player that can actually play it - and play it well....

Thanks for the replies. I have my eye on a Hofner, not the Beatle style, but rather a true acoustic body with built in pick up. I wondered what kind of sounds I might expect.

Bass.

Hmmm... That was one of my main concerns. I had images of midrange or maybe even treble emanating from it rather than bass.
