I am basically a one-man band in that I play everything myself. I don't have a bass guitar so I would have to make do whereas bass lines are concerned. Sometimes I just leave the bass out altogether, but when I do a bassline, I rely heavily on the Nether Octaver. You can really fine-tune the low octaves of your own guitar to make it sound just like a bass and it works great for me. Alternatively, if you think your rhythm guitar sounds a little thin with too little body, you can use this pedal to slightly make your rhythm guitar have a little more of a fat body and fuller sound. You'd have to fiddle around with that a little bit though, because if you put it up too much it quickly sounds as if you're playing chords on a bass, which is what you don't want. Just add a little at the time until you think it's full and fat enough. Really happy with this pedal: it's reliable, gives a good sound and again, does exactly what I bought it for. No frills, just a good sound for a very decent price! I would most definitively recommend this if you're looking for an Octaver!
