Acoustic Bass Modeler: ABM-1

Doesn't exist, but could. Zoom could do it. I think it would sell really well.

You play electric bass for a theater that primarily does musicals. You would like the ability to get the sound of a true acoustic, upright bass, just for when the part calls for it.

The first sweet thing would just be a nice pizzicato sound. The model would have adjustable settings for body, timbre, and even a way to adjust the decay so that staccato notes would "release" as they would with an upright, or quicker as they would with an electric, or points between. I've seen markings for vibrato on pizzicato, and if that could be properly modeled, that would be a nice option.

The next thing would be an arco sound. This would be trickier. It would require adjustable attack response, so the attack could be slower for soft notes, and progressively faster for loud notes. You could adjust the timbre, get some horse hair in there, adjust attack time, release time, as well as amplitude vibrato, and pitch vibrato, delay onset of vibrato, etc.

A tremolo arco (this is when the bow moves quickly back & forth), this would be a bit trickier, as it might need to be tempo dependent-- but something that had enough variability that it wouldn't seem like a sample-loop or a machine-like sound. I think samples might be helpful to get a flavor of it. A pedal could be used to adjust the tremolo speed.

The unit would need at least 3-5 switches. Pizz, Arco, Trem Arco, Vibrato, All Off. A preset could determine of the switches are momentary or toggle and what their function is.

The unit should also come with bunches of other bass effects, amp models, etc. etc. So it would really be a proper bass multi-effects along with these other functions. And as we discussed in another thread, a bass rig really does benefit from a parallel path, because bass can often be undermined by phase destruction between FX. A parallel clean path, or a parallel path with other treatments is essential.

Plan B might have just become available.

If I use something MIDImorphosis for pitch to MIDI, and use something like VirSyn's new AudioLayer app, I could use MIDI to trigger samples.

The only hitch is that AudioLayer doesn't seem to have any kind of control options for turning layers on/off. So it would allow one of those kinds of sounds, but not all 3.

There's other ways around it, and it is possible, but would require some A-level geeking.

Check eBay, Amazon, Craigslist, pawn shop for a Line 6 700 (4 string) or 705 (5 string) electric bass.

It's a nice idea, Jim. Thanks.

That acoustic bass model sounds pretty good! I've actually gotten to play an old K bass and they are impressive. It's an old cheap bass with surprisingly lovely low resonance.

Unfortunately, the Line 6 basses would be overkill in some ways, and underkill for what I'm envisioning. Also, my bass is already just what I want.

I might tinker with this pitch to MIDI notion a bit. Might be able to get a working setup.

I like Line 6's Variax guitars and basses. I think the guitars are an asset for gigging or session musicians that have a need to play both acoustic and electric guitars. Their basses kind of fall into the same territory. The instruments also provide variety on home recordings.

The first generation of Line 6 modeling guitars included acoustic, electric and bass body styles. Unfortunately acoustic and bass were dropped from the line-up.

Those guitars have always been interesting to me.

I recently got a Godin electric guitar with a 13-pin "synth access" out. I also got a Boss GP-10 which has lots of guitar & pickup models. It's impressive (except for things with pitch shift). Supposedly there's a bass version, but I suspect that Line 6 stuff will be better.

Needless to say, with my used Godin & used GP-10 purchases, I won't be buying any major gear for a while!!

There's a company called 3 Sigma Audio that does impulse responses (among other things), and they have an acoustic bass IR that is designed to take a DI from a Piezo-equipped bass and make it sound more like a mic'ed acoustic bass. The demo was impressive.

I emailed them to ask if their IR would work with an electric bass as a source, and they replied that they were a week away from announcing a new version that would work this way. I could route a switcher through my iPad.

I should ask them if bowing was at all possible. I kind of doubt it would work-- running a plucked electric bass into a bowed IR (non-pitched scrape)-- but who knows. I'll post back here when I hear something.
