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.

Hello, Effects Fans!

It's July.  It's hot, too hot for long announcements, so let's keep this short.

First, the Dallas International Guitar Festival has been postponed again.  The new date doesn't work out for us, so we won't be attending this year.  But we're already signed up for next year, so we'll see you then!

Second.  It took a while, but some ripple effects of the economic shutdown(s) have impacted us.  We have some suppliers that have temporarily or permanently closed their doors.  There may be some delays if/when we have to find new sources for a few of our parts.

Lastly, we used the quarantine time to focus on our R&D.  We have a bunch of new modules that we will be releasing soon, and we're excited about that.  The only downside is that we ran through our entire year's R&D budget about 6 months ahead of plan.  We may still squeeze in another or two, but most likely we will be going very slowly on that until next year.  We'll likely announce all these new modules together, so they will be available.  But after that, there will be a "dry spell" for new modules.  Once we announce all the new ones, our product line will have modules that compare to well over 300 different effects and pedals!  Yes, that's a lot of module choices!

That's it - stay cool !!!
