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!

It has been a while since my last update.  Our status has not changed much.  We are still unable to take new orders.  I’ve personally been off doing something completely unrelated, lots of fun, a long ways from home.  That has gone well, but is taking longer than expected.  Instead of finishing up about now, it appears I won’t finish before late Spring or early Summer.  Our status won’t change before then.

Parts availability and cost were primary causes of our current shutdown.  We use around 6500 different vintage and current production parts to build our rack effects.  It has been difficult to find good vintage parts for a while now, and it gets a little more difficult each year - nothing new about that.  Counterfeit and reject parts flood the market, and prices have soared as caches of legit parts dwindle.  The good news is that vintage parts are often not needed to get great-sounding effects.  Usually there are newer parts that will work as well or better if you can get past the volumes of misinformation and hype out there.  Listen with your ears, not your eyes!

Lack of current production parts forced us to stop taking orders.  Some critical parts do seem to be available again, at an increased price.  We want our rack effects to be affordable, and increased part prices are not helping with that.  For example, one part we use in nearly all of our modules, sometimes several per module, went from about 80 cents to around $5+ each.  Really?!?!  Fakes are also flooding the new parts market to fill the demand of the unwary.  However, a few parts are trending down in price.  In these cases there were too many manufacturers, and none of them were getting enough market share to make larger quantities to help reduce their costs.  Some have gone out of business, leading to consolidation and lower production costs.  We’ll take a cost reduction (and pass it along) anytime we can get one!  I’ll have to sort through our hundreds of effects and countless options to determine any impacts to our pricing.  My goal is to remain comparable to pedal prices.  Or better!

Where does that leave us?  The situation has improved, but we still cannot take new orders.  I’m going to work to finish up my side adventure.  I’ll pop up again, probably around June or July, and see how things are looking and provide another update.  

Best wishes for 2023 !!!

Hello, Effects Fans!

Today we announce our new Double Looper.  The Double Looper is actually a set of 4 different configurations of our Bypass Looper module.  As you might guess, the Double Looper is two Bypass Loopers in a single module.  These configurations take up the same amount of space, giving you two loops in the same space one loop requires.  That’s nice, but even nicer is that the price is much less than two separate Bypass Loopers!

Loopers give you the ability to control third party rack effects and pedals with the Gerlt Technologies rack switching modules and footswitches.  You can use them to turn on and off those nice, easy-to-see rack tuners (for example), using the same footswitch unit that controls your Gerlt Technologies rack effect modules.  You can also use a Looper to turn third party pedals on/off using your Gerlt Technologies switching and footswitch.  Utilizing our new 3U Pedal Rack that we just announced earlier today, you can conveniently mount your pedals in a rack and control them remotely using Looper modules and our switching technology.  This provides a way to continue mixing in third party pedals and effects, as well as giving you options to get started on a rack solution without having to replace everything all at once.

Gerlt Technologies rack effects are affordable and easy to use.  With the introduction of our Double Looper configurations and 3U Pedal Rack, you can combine the best rack effects with the best pedals, providing a world of options for your custom rack effects configuration!
