Hi,
I'd like to discuss getting an Double Bass sound with my electric fretless.
I have a Martin Peterson lightwave bass which you can see here...

I've been using Thomastik Acousticore strings which in combination with the lightwave pickup have a great acoustic vibe.
After reading some posts on getting an upright sound I thought about how to appoximate the complex tone of an upright bass and tried the following things:
1) Raised my action to eliminate the fretless whine/buzz
2) Plucked the strings real hard near the neck.
3) Observed that the string tension of the acousticores, even as low as it is, causes the tone of a note to become dull quite quickly even though the volume sustains well.
4) In order to make plucking a high action with a hard attack easier, and to allow the string to vibrate in a more complex unchoked manner, I tried detuning The A, D and G strings to E, A and D respectively.
The result was the best upright bass approximation I've ever heard. The strings sound in tune at the lower tension and vibrate with a much more complex pattern which sounds remarkably close to the longer scale upright bass strings.
I'd be interested in other players' experiences along these lines.
Thanks,
John
