Hello Effects Fans!

It seems like time for another update, but not much has changed.  The supply chain problems continue to make parts unavailable and there is no particularly believable plan or timeframe I know of for these problems to be resolved anytime soon.  Perhaps early next year?  Perhaps not? 

We lost another supplier that has been supplying boards to us for several years.  Luckily, there are other suppliers that can make our boards and we’re in the process of switching to one of them.  We’ll have to go through a testing and validation process with the new supplier to make sure there are no technical glitches in getting our specs to them and that their results will meet our quality standards.  This takes some time, but we should have that resolved before parts become available.

I’m concerned that more parts may become unavailable if the supply chain problems continue.  Available stocks are being depleted.  I’m also concerned that demand for dwindling supplies, as well as the increasing cost of energy and transportation, along with high inflation, will force us to have to raise prices to cover the increased costs.  Shipping costs have always been an issue, but are now often higher than the cost of the items being shipped.  That represents a significant overall cost increase.  If you’ve been following us, you know that providing the best selection of the best rack effects is our mission.  But you will also have seen our frequent use of the word “affordable” in our objective.  It’s not difficult to make expensive things that few can afford.  We want our rack effects to cost no more than pedals, less when possible.  We’re nearly there and will do everything we can to avoid going backwards.

While the outlook is not what I would like, it’s not all doom and gloom!  I don’t idle well.  I run best near the red line!  To that end, I dug through the R&D backlog and knocked out another 10 – 20 new module configurations.  I know I shouldn’t be doing that right now, but who can sit around and do nothing for this long?  Not me!  Many of these are what you might call “new classics”.  If you consider the “classics” as being those ground-breaking effects of the 60’s and 70’s, these new classics are mostly from the 80’s, 90’s, and early 2000’s.  There were a lot of great effects released in that timeframe and these will make very nice additions to some thin spots in our offering.  With these new modules, the number of effects we “compare to” in our offering will be over 350.  That is *a lot* of effects to choose from, all in rack format and built by hand here in Dallas to suit your needs.

That’s it for now.  I probably won’t send another update until after the holidays, when hopefully parts will become available and there will be more interesting news to report.  Until then, all the best to you and yours through the upcoming holiday season, and thank you for your continued interest in the world’s best selection of the best and most affordable rack effects available!

Gerlt Technologies makes hundreds of customizable rack effects, at prices comparable to regular guitar pedals.  It's time to dump that pedal board and get Your Tone off the floor!


 What We Do

You know them as guitar pedals

We build them as rack effect modules you can customize to get Your Tone

Put several rack effect modules into a 3U rack enclosure

Connect power and audio on the back like guitar pedals, adding connections for remote switching

Add a remote footswitch unit to turn rack effects on and off

Add as many rack effect modules, enclosures, and third party products as you like. Plug in your guitar and amp. Rock it! It's that simple.


Quick Hits:

  • Check out our GT Effects Overview to see why we do this

  • Check out our Compares To charts to see the full list of effects we offer

  • Follow the menus from Products, to Modules, to Modules By Type to get a list of our effect types.  Select any effect type to get a list of all our effects of that type.  Select any effect to get full information including pricing.




Those of you that have stopped by our booth at a show know that we have third party tuners, pedals, and noise reduction systems in our demo racks. We only use the tuners. The other third party stuff is just there to show some good options for other gear you might want to consider when you move to a rack setup. Those tuners, pedals, and other third-party equipment have one annoying downside – they each require a transformer, or “wall wart” for power. Since we also have good third-party power conditioners in our racks, we have plenty of outlets to plug in those transformers. The problem is there is no good way to secure them. When we move our rack cases around, pack them in trucks, turn them upside down, and generally mistreat them, those transformers come unplugged and bounce around, potentially damaging the transformer or anything it bounces into. Not good! Those transformers can also be a source of annoying power supply noise that can easily find its way into the audio signal. Also not good! Some transformers are either too large or have a poor physical design, making it difficult to even plug them in to some power conditioners. That’s just downright annoying!

Now we have a solution for those problems – the Warthog. The Warthog module takes in a standard GT 18V Power module feed, just like our other modules. It then converts that into four different output channels. You get to choose either center positive or center negative polarity, and the voltage for each of the four output channels. Voltages are all DC, not AC, and are regulated to about +/- 10%. Common choices include: -9V (100ma), -3V (100ma), -1.5V (100ma), 5V (100 or 1000mA), 9V (100 or 1000mA), 12V (100 or 1000mA), 15V (100 or 1000mA), and 18V (100mA). Other configurations may be available – let us know what you need. You can daisy chain from these channels, up to their mA limits. You can use both positive ground and negative ground effects, but not on the same channel. The Warthog is intended to be used with our 18V Power module, so that we do not have to duplicate some of the protection circuitry provided by the 18V Power module (and lose some power in the process). However, we can add a protection board so you can power it from a third-party power supply if you prefer. Using it with the 18V Power module gives you the ability to see your mA usage so you can balance your power consumption and not exceed the maximum number of mA for the Warthog or 18V Power channels.
