I think of my octavers like different oscillator flavours, in the same way that on a synth you’d choose between Square/Sawtooth/Sine etc depending on the texture you’re after sonically. If you recall, I sold one or two of my octavers which covered similar ground to other pedals I owned - got rid of the Digitech Bass Synth Wah because the Octave sounded quite similar to my Aguilar Octamizer and got rid of my Emma Okto Nøjs because it covered similar sonic ground to my 3Leaf Octabvre Mini. My current trio all sound totally different to each other, just as I would expect different oscillator wave shapes on my synth to be.
Basically what I’m saying is almost everything the Kolrg Volca Bass can do, you already have the ability to do with your JD, and more. Just trying to be the voice of reason.
6’8” actually but my point about the JDXi’s portability would still stand if I were 4’10”!
