Thanks for all feedback, guys...
Harry, these Impedance issue is just what was told to me, not just with the Mammoth but it seems to be a problem to all Fuzzess. Fortunately we all know there are some Fuzzes that can be more gentle with buffered signal, so I went to hear Mastotron trough ZVex's Site, but it didn't seems to deliver what I'm looking for. I'll e-mail people at ZVex asking if they intend to release some active input version for the Mammoth, since its peculiar gated sound is something I miss on every other Fuzz I've heard.
Ken, I'll try Dano's Cool Cat. Frantone's Peach Fuzz sounds really great and 40 bucks is really tempting (although I tend to feel their Basssweet too dark to my taste). Great new knowing it works along Active signals, this is the kind of Tip I expected when wrote here. Thanks to you and Graemme.
Hey Jack, Pigtronix is world wide known and well respected (no need to disclaim). Loved their products, some of the finest pedals I've ever heard. To be honest I didn't specially liked Disnortion, but now I MUST have their Mothership Analog Synth and Envelope Phaser. Thanks for the crave, by the way... LOL
Terry, some years ago I tried Zoom's 506 and didn't like it at all. But I didn't tried its Fuzz patch and people are saying they really improved their multieffects in the B series. So, despite being somekind of Analog Type guy regarding to Efects, I'll try it someday.
Thanks everyone!
