 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!

New Module: Sultan of Squeeze

Published: 23 August 2019 23 August 2019

 

 

Some tunes are timeless classics, like Dire Straits’ Sultans of Swing. Mark Knopfler’s smooth playing will keep this song on playlists for many more decades. A Musitronics Dan Armstrong Orange Squeezer compressor was used to help get that smooth tone. There aren’t many effects that could be simpler. The only control was an on/off switch. Many players probably had their Orange Squeezer modified. It came in an enclosure with a built-in jack that made it a little inconvenient to use.

Our Sultan of Squeeze compressor compares to the Orange Squeezer, but comes in a super-convenient rack module format, of course. We also added a very simple Level control so you can dial in unity gain or a boost. Otherwise we stay true to the original design. While primarily for guitar, you can get it with a couple of minor mods to make it work great for bass, too. Our Sultan costs much less than an original Musitronics version of the effect, so you can get your smooth groove going.
