I am so stoked. I just traded a Russian Small Stone, newish MXR Distortion+, and Boss CS-3 for a mint Nine Volt Nirvana Dinosaur Fuzz pedal. I love the sound and versatility of this pedal. With the main switch on I can have it completely fuzzed out with tons of low end and clarity, and with the other switch on I can get ear-scraping Shellac-style tones from it. I'm wondering two three things: 1. What settings have you found to be best for different tones? Right now I have mine set like this for a good fuzz (bass+clarity) tone + the Shellac sound: v 3:00 t 12:00 g 3:00 r 7:00 First in my effect chain; going into my Silvertone 1484. 2. Have any of you messed with the innards of this thing at all? The letter that came with it mentioned switching stuff out. Is it relatively easy? I can solder, but am by no means an electronic wiz. What have been your results? 3. What kind of power supplies have you found to use with these? I know I can't use it with my Furman pedal board because of the positive polarity.
