Gerlt Technologies makes hundreds of customizable rack effects, at prices comparable to 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.

Hello Effects Fans!

In my last update I was excited after finding some small quantities of critical components that are needed to build our effects. I hoped that to be a sign that perhaps some of our supply chain problems were easing. But it seems those were just one-off lucky finds. I haven’t found any more since then. On top of all the other problems, we now have the ripple effect of the conflict in the Ukraine, which has caused even more parts to become unavailable and/or very expensive.

It’s one thing to be optimistic, but another to be unrealistic. This is no longer a time for simple optimism. It is a time for handling unpleasant realities. Our reality is that it seems very unlikely that enough positive changes will occur quickly enough for us to re-open in 2022. While the corporation is in a good position to weather a continued lengthy shutdown, the people are not able to. We need to take some time to go do “other stuff” for a while.

We still have several new modules to announce. The work is complete on almost all of them, so I’ll try to get those announcements out in April and May. Other than that, I’m afraid it is going to be pretty quiet here until we are able to reliably source parts at reasonable prices again. I probably won’t have another update until late summer or into autumn.

The good news is that Gerlt Technologies is still here and alive. We haven’t “lost” anything. We still have the largest selection of rack effects available, getting close to 400. Our effects still sound great. And we still want to make them available to you. We’re just going to have to continue our break for a while until the business and economic conditions improve to the point that we can provide outstanding products and support at affordable prices.

I apologize for the continued delay and will do everything I can to get us going again as soon as it becomes feasible.

Hello, Effects Fans!

Today we announce our new Double Looper.  The Double Looper is actually a set of 4 different configurations of our Bypass Looper module.  As you might guess, the Double Looper is two Bypass Loopers in a single module.  These configurations take up the same amount of space, giving you two loops in the same space one loop requires.  That’s nice, but even nicer is that the price is much less than two separate Bypass Loopers!

Loopers give you the ability to control third party rack effects and pedals with the Gerlt Technologies rack switching modules and footswitches.  You can use them to turn on and off those nice, easy-to-see rack tuners (for example), using the same footswitch unit that controls your Gerlt Technologies rack effect modules.  You can also use a Looper to turn third party pedals on/off using your Gerlt Technologies switching and footswitch.  Utilizing our new 3U Pedal Rack that we just announced earlier today, you can conveniently mount your pedals in a rack and control them remotely using Looper modules and our switching technology.  This provides a way to continue mixing in third party pedals and effects, as well as giving you options to get started on a rack solution without having to replace everything all at once.

Gerlt Technologies rack effects are affordable and easy to use.  With the introduction of our Double Looper configurations and 3U Pedal Rack, you can combine the best rack effects with the best pedals, providing a world of options for your custom rack effects configuration!
