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.

Hey, DFW!!!!  It’s coming soon!  The 2020 Dallas International Guitar Festival is Friday – Sunday, May 1 -3, at Market Hall.  You know what I’m talking about – loads and loads of guitars, amps, and everything guitar-related, along with great international and local bands all-day, every day!  It’s always a fun time, not to mention a good place to find that piece of new or vintage gear you know you need!

As you’ve probably already guessed, Gerlt Technologies will be there again this year.  Come by and try out our “Big Stack” of affordable, custom rack effects.  We’re still configuring our demo setups for the show, but we normally have about 175 – 200 different hand-built rack effect modules in our booth for you to try out.  We have several new ones that were released since the last DIGF, or even since the Ft Worth Guitar Show last October.  We aren’t there to twist your arm or put a hard-sell pitch on you, so relax and give them a try.  We’ll explain what we have and how it works, then plug you in so you can hear why we enjoy the opportunity to show-off a little.

We know it is hard to believe “affordable” and “custom rack effects” could be mentioned in the same breath, but it’s true.  Our module pricing is about the same as pricing for comparable pedals.  Check out the details, including pricing,  on the pages for each of our modules.  Compares To is a good starting point.  Follow us on Facebook “GerltTechnologies” to get occasional news updates like the ones you’ll see on our Facebook page.

See y'all there!
