Hello, Effects Fans!

Yes, it is once again time to announce a new GT effect module.  But today, it's going to be a little different - are you ready?

First, our new module is called the Bee All module.  But you cannot buy a Bee All.  Nope, we don't offer any Bee Alls for sale.  

Second, we aren't just announcing a new module configuration.  Or even two new configurations.  Or five.  Or ten.  Or twenty.  Yes, this is crazy.  We are announcing 28, yes, twenty-eight, 2-8, new module configurations!  This is what happens when we get locked up for quarantine and spend far too much time in the lab!  New products come streaming out at an epic rate. 

So what are all these new configurations?  We won't go into full details here, as that would make our normally-already-too-long announcement too much to digest at once.  You probably noticed that this announcement doesn't include pictures of the new module configurations and pedals they compare to, as our usual announcements do.  Again, including all those pictures is just too many for one posting.

If you use guitar pedals, you probably know of BJFE, Bearfoot, and Mad Professor pedals.  And you probably know that those companies are somehow related and sell some similar designs.  Many of those designs are based on a single "parent design", with some tweaks to parts, or with small pieces of the circuit left out or modified slightly.  Our Bee All module design supports a large number of those BJFE, Bearfoot, and Mad Professor designs.  At present we support 28 different versions of several different pedals released under those brand names.  Some of the pedals include:

  • Blueberry Bass Overdrive (yay!  more bass configurations!)
  • Honey Bee
  • Uber Bee 
  • Silver Bee
  • Honey Beest
  • Dyna Red Distortion
  • Model G
  • Model H
  • Sparkling Yellow Overdrive

These, in their different brands and versions, make up the 28 new module configurations we are announcing today.  We said above that no Bee Alls are for sale.  The reason is due to our need to distinguish between all these Bee All module configurations.  We left "Bee All" out of their names to keep the names from becoming too lengthy.  So, no, there aren't any of these configurations for sale that are called a "Bee All".  You order them by their individual names instead.

To see all the specific configurations we offer, options, pricing, etc, check out the BeeAll page for full details.  You can also find the Bee All page listed in our Amp Sim effects, as all the configurations were designed to sound like specific types of amps.  You can follow the menus to get there:  Products -> Modules -> Modules By Type -> Amp Sim.  Or search for "Bee All".

With this announcement, we now offer GT module configurations that compare to well over 300 different guitar effects/pedals.  We understand that to make a rack solution most effective, you need a wide range of effects to choose from.  That was one of the problems with previous rack effects offerings, decades ago.  There weren't enough effects to choose from.  There were other problems, too, like high cost.  Gerlt Technologies has completely re-imagined what rack effects could be, and made it happen.  We are committed to offering a wide variety of rack effects at prices comparable to pedals.  With well over 300 effects to choose from, and an average price per module that is competitive with good pedals, now is the best time in all of effects history to make the switch to a rack solution from Gerlt Technologies.  All it takes to get started is an email to This email address is being protected from spambots.
