Oso Negro Fuzz - Prototype Sound Test by GodaSound published on 2012-01-31T16:54:02Z Three controls here - input level (acts like a fuzz control), choke (chokes the signal, listen for the glitchy or zippy sounds in the demo) and volume. I may get rid of the choke control - I'm not sure I like the sounds much, but then you can leave it maxxed for the regular fuzz sound . . . who knows at this point. I really like the sounds possible with this pedal - very cool. Comment by GodaSound Setup used is: Agile AL-3000M into pedal into Carvin V3M through an Eminence Texas Heat 12" into a Sure SM-57. The pedal is always on during the demo. The cleaner tones just have the input control dialed down a bit. The amp is setup for a clean, flat tone with a little bit of reverb. 2012-01-31T16:55:50Z
