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!

Today the message is unpleasant.  After figuring how to deal with some of our government’s policy decisions for the past several years, I must finally admit defeat.  It is not feasible to continue operations with the latest round of policy changes.  As recently as a few days ago, I thought it might work out.  Then I was hit with business-ending tariff charges, with more to come.  To be clear, it isn’t just these new Trump tariffs that have beaten me.  Biden-era tariff changes and policies were also difficult to survive.  The cumulative effect is too much.  

As an entrepreneur I take calculated and managed risks.  Sometimes it works out, and sometimes I seem to be shooting at my own feet.  But I can’t survive an economic nuking from my own government.  It’s not just a political disagreement, or differing opinions, theories, or expectations.  It’s a matter of undisputed facts, real dollars.  Gerlt Technologies’ “Game Over” criteria were met this week as those facts became crystal-clear.  I don’t like politics and refuse to take part in it, so I’ll just leave it at that.

Gerlt Technologies will no longer take new orders for our effects.  We do still have our popular 3U Pedal Racks available until our inventory is depleted.  New tariffs on metals will make them too expensive to restock, so get ‘em while we’ve got ‘em!  I have a handful of new modules that I’ll be completing soon.  I’ll still announce them when they are finished, just ‘cause.  We were already contemplating thinning out some of our guitars, amps, pedals, and maybe some components and other gear that have somehow quietly filled up all our available space over the past several years.  We may add some listings for those on the site or perhaps on Reverb in the coming months.  Keep an eye on us if you are interested in some lightly used gear in great condition.  I expect and plan this shutdown to be permanent, but maybe I’ll pop up and take a look around in a couple of years if enough major changes take place in government policy after the mid-term elections.   

It has been a lot of fun!  I enjoyed meeting thousands of you along the way – always the best part of any adventure.  Thank you all, and all the best to you and yours!

Returning to Ft Worth!

Published: 06 August 2019 06 August 2019

It’s official – we’re headed back to Ft Worth!

Come visit us at the 2019 Amigo International Guitar Show in Ft Worth, Texas on Oct 5 – 6, 10am – 5pm, at the Will Rogers Memorial Center. Come for the show and afterwards head to Sundance Square, The Stockyards, Billy Bob’s, or other happenin’ spots in Ft Worth and make a day of it!

We’ll be there with our Big Stack of over 200 rack effects that you can try out. Don’t let the Big Stack scare you, though. We bring around 200 effects, which is about 10 to 30 times larger than a “normal” setup.

For those of you unfamiliar with Gerlt Technologies, we are a small Dallas-based company that builds customized rack effects. We do that in a unique way that takes up less space and costs far less than normal rack effects. We try to keep the cost of getting into a rack effects comparable to the cost of a good pedal board, power supply, pedals, and pedal switching system. Our rack “modules” are the counterpart of normal pedals. Our module prices are comparable to the hand-built boutique pedal prices. We want them to be within the reach of all players, not just superstars.

Since we design all of our own boards, and we have more space for circuitry in a rack format, we can offer up many options and mods that allow you to customize your modules the way you want them. Our modules compare to popular and well-known pedals, as well as many lesser-known, uber-expensive pedals that most players will never be able to try, much less purchase. Our modules cover a wide range of effect types – boost, chorus, delay, distortion, flanger, fuzz, overdrive, phaser, signal routing, switching, vibrato, and others. However, if we don’t have something you need, no problem. Our solution is completely compatible with normal guitar pedals and third-party rack effects.

But the main reason to use our effects is because they sound great! Come visit our booth at the Ft Worth show and we’ll explain how it works (which takes about 1-2 minutes) and let you play them. Of course, they are all made in Dallas by hand “old school style”, with no disposable, mass produced, surface mount technologies. You can pass these effects down to your grandkids!

To see more info, look under the Products -> Modules -> Compares To menus to find a list of over 200 well-known effects that our modules “compare to”. There should be some new ones announced between now and the show, so follow us on Facebook to get occasional news and product updates.

See y’all in Ft Worth!
