Hello, Effects Fans!

Today we announce our new InAGaddaDaFuzza module.  It compares to the Mosrite FUZZrite and the recently-released Catalinbread FUZZrite.  

There were a number of new fuzz pedals hitting the market in the 60's.  The Mosrite FUZZrite was one of them.  It's a little difficult to say with certainty who used what fuzz back then, but it seems fairly certain it was the fuzz used for Iron Butterfly's multi-platinum In-A-Gadda-Da-Vida.  It probably wasn't used by the Ventures, although it probably does give you the sound they were looking for at the time.  It probably was not used for Spirit In The Sky either, but it gives you a similar fuzz character - a little nasty and gnarly, a bit low-fi, maybe good for garage punk.  But with some fiddling about, you may find that fuzz sound heard on a number of 60's bands, particularly those in California at the time.  Recently, Catalinbread worked with the Moseley family of the original creators to build a reissue of the FUZZrite.  It compares well to the original.

The earliest versions of the FUZZrite used germanium transistors, while later versions were silicon.  You get a similar fuzz tone from both germanium and silicon transistors, or even a mixture of the two.  However, the germanium versions seem to sizzle and gate out, maybe just what you're looking for, maybe not.  In our opinion, silicon transistors are the way to go.  We have the same uncommon transistors used in the Catalinbread remake, or we can use something else if you have a preference.  Either way, it's a rude, in-yo-face, stick-it-to-the-man fuzz, a bit like the Gibson FZ-1 used by Keith for Satisfaction a few years before the Butterfly took wing.

You can see the details about our InAGaddaDaFuzza module at: InAGaddaDaFuzza.  Or look for it in the Fuzz Modules section under Products -> Modules -> Modules By Type.
