Hello Effects Fans!

It has been pretty quiet here since my last update, as expected, but not silent!  Earlier today we announced our new 3U Pedal Rack and our new Double Looper configurations.  These two offerings are designed to make migrations to our rack solutions easier, providing more and better ways to continue using your third party rack effects and pedals in an all-rack solution. 

Our status hasn’t really changed much.  You are probably aware that there are some serious supply chain problems in the electronics world.  Those shortages are affecting the availability of many end products from appliances to automobiles, to, yes, Gerlt Technologies rack effects.  We are simply unable to get some critical parts right now.  Projected back order dates come and go with no new parts becoming available.  For us, these are simple, but critical parts used in our circuits.  They haven’t stopped making them or anything like that.  It’s just that they aren’t able to make enough of them fast enough with staff, facilities, and transportation that continue to be impacted by COVID all over the world.  Of course, the small supplies that are made are going to The Big Guys first.  It will be a while before availability trickles down to smaller companies.  That’s just the laws of supply and demand in action.  It will eventually get sorted out, but in the meantime small manufacturers like Gerlt Technologies will just have to wait.  That’s why we stopped taking orders earlier this year.  We plan to be a survivor, not a casualty, of the COVID aftermath.  I still don’t know when we’ll be able to restart, but some of our latest backorder dates for parts will almost certainly push a restart into early next year.

The best news is that live music is back!  Every day I see more and more info about tours and local shows.  I hope that all you professional and gigging musicians are getting more bookings – we’ve missed you!  For all of us that don’t play publicly, COVID has been a nasty reminder about taking our lifestyles for granted, as has been the passing of some great musicians like Dusty Hill and Charlie Watts.  Enjoy your favorite music live (and safely) when you can!

We appreciate your patience with us during our temporary shutdown.  Once things are back to “normal enough”, we’ll be ready to do what we can to earn your business and get you into some excellent rack effects.

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.
