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: Ruby Drive

Published: 15 November 2018 15 November 2018

 

 

 

 

 

We’re happy to announce the availability of another new module.  Our Ruby Drive compares to the JHS Ruby Red and Superbolt pedals, designed to sound like those vintage Supro amps used by numerous artists, including Albert Lee, Jimmy Page, Jimi Hendrix, Joe Perry, Joe Walsh, Steve Stevens, Keith Richards, and many others.  The Ruby Drive is easy to operate, with Volume, Gain, and Tone controls, along with a Hi/Lo switch.  At low Volume and Gain, you can get a spanky, sparkly clean boost.  Crank the Volume and Gain all the way and you get saturated, singing sustain, hi-gain distortion, practically fuzz.  There is a wide variety of boost, overdrive, and gain tones in between.  JFET transistors result in a nice tube-y sound – nice woody, hollow palm muted tones when the gain and volume are up.  It is nicely sensitive to pick attack and cleans up with your guitar volume.  Switch from Hi to Lo, and the gain and treble get trimmed a bit to darken the mood.  It has one of the widest ranges of great drive tones of any module we offer.  You can see the details and pricing at Ruby Drive.

That’s all for now.  We were hoping to pair this with another product announcement that is nearly ready, but we’re still waiting for some parts to arrive.  They should be arriving any day now, so check back around the end of the month or first week of December to see what we've been cooking up besides turkey.  We’re going to be on short hours the week of Thanksgiving, but we’ll be checking email periodically.

Have a Happy Thanksgiving !!
