Find a modeling amp with either an octave effect or a harmonizer that does the sub octave, and dial the effect 100% wet. That's what I do with my Johnson JM150 when I don't have any of my stomp boxes.
It's mainly an issue of octave. Once you have the right octave, you can do a ton of stuff to the tone to simulate a bass. But as long as you are up one octave from a bass, it'll never sound like a bass.
If you want the bass guitar range in a package that has string-to-string tuning like a guitar, get one of the cheap Squier Bass VIs.
Anything with a pitch transposer or harmonist can *kinda* sound like a bass, but we are talking maybe 60% at the most. There is no substitute for the real thing. I have used a guitar synth to play bass at gigs before, and that worked well. I used samples of a real fretless, though.
Even a cheapie will sound far, far better than a good guitar through an amp/effect
Disposable-grade Ibanez GSR-200's can be made to sound quite killer with an active pickup upgrade, although the necks on them are weak as hell and have lots of flex... stick to lighter strings with stuff like that
For a surprisingly solid ready to go package, there the maple-board squiers with the black block inlays (I forget the model name)
That's the move. Just pick up an inexpensive bass set up. I paid $80 for my Washburn AB10 and $59 for my Peavey Micro Bass amp. The set up sounds great for writing, recording and home practice.
Thank you all, for the info. I ended up getting an Ibanez acoustic elec. short-scale bass. It's small and light, and easy to pick up anytime and play around with. I'm very happy with it.
Regarding the octave pedals is the wet setting on the pedal or is it the amp that does it?
That’s the worlds largest ukulele I ever done see.
I bought a Gretsch G2210 bass when I was in your shoes. But I’m sure that vintage uke will do the trick just as well or better. Least you can play campfires.
