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.

Hey, everyone! Hope your summer is going well.

It has been a little quiet lately, but our R&D logjam is starting to break loose. Today we announce our new Ratverb module. The Ratverb compares to the Realistic Electronic Reverb 32-1110. The original unit was intended to add a reverb effect to just about anything you could plug into it, such as record players, TVs, microphones, instruments, and audio components. It had a Mic In and a Line In. If you used the Mic input which was intended for instruments and other gear with a quarter inch jack, then you had control of the overall input gain with the Mic Level control. At low levels you get a “small room” analog reverb, based on the old Panasonic MN3207 bucket brigade delay chip. But as you turn up the Mic Level, it quickly began clipping and distorting. About halfway up was a nice overdrive sound, a little further was heavier distortion, and full up you got a nasty, spluttery, rude fuzz, sounding very similar to the Maestro FZ-1 Keith Richards used for the riff of riffs in “Satisfaction”.

The Ratverb closely follows the original circuit design and behaves the same way. With the Gain on zero, you get a slightly warm reverb with just a hint of extra grit and a slight boost. Turning the Gain up goes through all the levels of OD, distortion, and fuzz, just like the original. Although technically a delay, the very short delay time makes it difficult to use as a delay. It’s best as an analog reverb, giving a “small room” model, with or without the dirt.

It's sort of an odd pairing – boost/OD/distortion/fuzz with an analog reverb, but also oddly addictive. Cranking it up with a strat will definitely give you some satisfaction!

Check out all the details for the Ratverb. And keep an eye on FB for more upcoming announcements!
