Hello, although a year has passed since you posted this, please consider my experience as a guitarist that was looking for similar ways to play other instruments on the guitar. In the 80s when Roland released guitar synthesizers, I was dead set of owning one. As a matter of fact one guitar/controller was so good as a guitar that the “guitar Gods” of the time, John McLaughlin-Al Di Meola-Pat Metheny, were using that controller (GR-303 & top model neck through 808), to drive the one and only Synclavier.
I rushed to the music stores to try out the guitar synth but nothing sounded the way I imagined. A friend & keyboardist pointed out that trying to play a Hammond on the guitar will never sound like at.
Now you can say that bass/guitar are practically identical. After playing guitar for 10 years I switched over to bass and it required a new approach, different dynamics, etc. I recently faced a similar situation as I was toying with the idea of getting a baritone guitar. Then I was looking at octave pedals , detainers, even a Squier bass VI that someone was giving to me. Nothing worked. A baritone tuned B-B is a baritone, nothing else.
Get an Octave pedal, and experiment with that. It’s not a bass replacement by any means, but it will help you unlock different ideas and make you consider other paths while playing.
Cheers!
