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 AstroFuzz module.  The AstroFuzz compares to the AstroTone Fuzz, Sam Ash Fuzzz Boxx, and Analogman AstroTone.  There was also a recent re-issue of the Sam Ash Fuzzz Boxx, which sadly seems to be about as rare as the original units. 

The opening riff in Elton John's Saturday Night's Alright has one of the classic 70's guitar tones.  It gets better every time you hear it!  If you haven't heard that tune in a while, head over to YouTube right now and give it a play.  We'll wait...

Did you also play The Bitch Is Back and Tiny Dancer while you were at it?  OK, we'll wait again...

OK.  That's better.  It isn't certain whether Davey Johnstone used an AstroTone Fuzz for Saturday Night's Alright, but many believe he did and it sounds exactly like it, whether he did or not.  While it is called a fuzz, it is more of a high-gain overdrive that maintains its clarity and articulation, without being too compressed.  It's a very open tone that begs for the volume to be cranked up.  More.  It is addictive and could easily become a key component of your tone.  Buffalo Springfield's Mr Soul, Neil Young's Cinnamon Girl, and some Boston tunes might also be dialed in.  In addition to classic rock and pop, it is excellent for blues and country.  It also handles bass better than most high-gain overdrive and fuzz pedals.  We like it served straight up, but it should also be a good effect for stacking.  Would love to try it in front of a hot Hiwatt, with a bit of windmilling on a P-90 SG, but don't have a P-90 SG...  yet...  If you have a clean-tone song that needs a little something more, a light dose of this might be just what you're looking for.

The AstroFuzz has quickly become one of our favorite modules.  It's as good as beer.  We keep to the original tone and design, but have a couple of options worth considering.

Such a classy, sassy tone and very fun to play.  It definitely puts a smile on your face!  It's like a time machine back to fun summer days of the mid-70's, rockin' that AM radio with Elton John, bell bottoms, and a cherry Kool-Pop while playing Jarts!
