Brilliant, a true Basschatter! 😆
It has been mentioned previously, but if you find a fiver isn’t for you, go with the drop D tuner, I’ve used them for years and have them fitted to the majority of my 4 stringers. You get used to compensating for the lower tuning really quickly. The only drawback is when you forget to reset it and launch into a tune only to find you’re a tone flat (tell folk it’s a jazz harmony 😉😆). An octave pedal probably won’t really do what you want, I’ll use it in that scenario for maybe a note or two at the end of a song, or a particular section, but not for the whole thing (unless I’m channeling Tony Levin, Pino or Guy Pratt of course).
