I just fidddled around like an hour comparing the Octave Multiplexer and a Micro POG on a P-bass (I use a Stingray, but I couldn’t take it to the shop that day). I also threw in the Bass Muff I was buying at that very moment.
The sound of the Multiplexer is YUMMIELICIOUS!! Its analog, dirty, sub-bass octave sound is really great! Both with the Sub Switch on and off it tracks really well and sounds awesome. Only problem I found is that it can’t go below a normal B note. It does well as far as a C, but anything below that it starts glitching and going mad. I’d of bought it had I not have like three dirt boxes to take care of already getting that “dirty sub-bass sound”
The Micro POG, on the other hand, is as clean as a whistle! Tracks on the spot all the way down to a dropped-D tuning (In this case it was the amp that couldn’t handle the note). On all of the YouTube vids I had found the upper octave sounded thin and fake, and it does! However, if you mix just a little bit of it (I never got it past 1 o’clock) you can make sure you’ll NEVER get lost in the mix. The sub-octave doesn’t sound quite like your original tone, but if you keep your dry signal at input level it’s hardly noticeable (And I bet in a band situation nobody will notice it).
Bothsound rather good with the Muff in front of them, but the Multiplexer gets quite muddy (after all, it sounds dirty by itself) whilst the M-POG just fattens up your sound. As I knew on my last post I’ll save up for the Micro POG.

Hope my extensive post helps in any way

PS: Check out my band, I use a lot of EHX effects in our songs (Mostly live, but still )

Me lo imaginé, pero como el forum es en inglés y asñ­ como yo di con él por Google, no dudo que haya muchas personas que no hablen españ±ol y lleguen por acñ¡ a intentar acabar con su duda. Simplemente aportando mi granito de arena
Gracias por el comment sobre mi banda
