My first octave pedal was a Voodoo Lab Proctavia. It just sits in its box in the bottom of my pedal trunk these days. I have an Octron from the first batch (#24) that I have since had Dave Fox bring it up to current spec (low octave mod). I really like the Octron as it does what it does really well. But whether in Mode A or Mode B, it still gives you the upper octave all over the fretboard. So I have been wanting something more Octavia-ish. Something that is not so perfect like the Octron is. I am waiting on a Karl Fuzz which I hope to get sometime soon. The Karl from the clips I have heard seems to be the one that is really going to get me where I want to be in terms of octave/ring mod goodness. So in the meantime, I went ahead and grabbed a new Fulltone OctaFuzz yesterday. The main question that I have is, is the OctaFuzz really as close to the original as Mike Fuller claims? I spent a considerable amount of time with it last night and it is cool but I am not sure just yet if it is doing it for me. I found that the boost needs to be set to no higher than 12 o'clock for the octave to really come through but at this setting, the pedal overall sounds a bit thin. Adjusting the volume knob really makes a big difference in the sound and reaction of the octave but getting these two knobs right has not been easy. I have tried running it before and after other boosts, fuzzes and whatnot on my board but it seems to sound best on its own. I have done a search and it seems like this topic hasn't come up in a while. So is there anyone out there that thinks the OctaFuzz nails it? Or what do you prefer over it?
