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.

Hi Everyone!

The Amigo International Guitar Show, formerly known as Guitarlington, has moved from the Convention Center in Arlington to the Will Rogers Memorial Center in Ft Worth, Texas.  It will be held the first weekend of October each year at the new location.  This year it will be on Sat/Sun, Oct 6 & 7.  It is one of the largest guitar shows on the planet and a great place to find some new or vintage gear. 

Here's a link to their site for show info:

We'll be there, with somewhere around 200 of our modules for you to try out.  We'll also have a variety of guitars and amps so you can hear our effects through a guitar and amp of your choosing.  Stop by and give 'em a try!

Of course, we'll be able to show you details of how everything works and answer any questions you may have.

Plus, anyone that stops by our booth and places an order in October will qualify for a 15% discount on their entire order. 

So join us at the Will Rogers Memorial Center in Ft Worth on October 6-7 and put the Rock in Rocktober !!!
