Hello Effects Fans!

It seems like time for another update, but not much has changed.  The supply chain problems continue to make parts unavailable and there is no particularly believable plan or timeframe I know of for these problems to be resolved anytime soon.  Perhaps early next year?  Perhaps not? 

We lost another supplier that has been supplying boards to us for several years.  Luckily, there are other suppliers that can make our boards and we’re in the process of switching to one of them.  We’ll have to go through a testing and validation process with the new supplier to make sure there are no technical glitches in getting our specs to them and that their results will meet our quality standards.  This takes some time, but we should have that resolved before parts become available.

I’m concerned that more parts may become unavailable if the supply chain problems continue.  Available stocks are being depleted.  I’m also concerned that demand for dwindling supplies, as well as the increasing cost of energy and transportation, along with high inflation, will force us to have to raise prices to cover the increased costs.  Shipping costs have always been an issue, but are now often higher than the cost of the items being shipped.  That represents a significant overall cost increase.  If you’ve been following us, you know that providing the best selection of the best rack effects is our mission.  But you will also have seen our frequent use of the word “affordable” in our objective.  It’s not difficult to make expensive things that few can afford.  We want our rack effects to cost no more than pedals, less when possible.  We’re nearly there and will do everything we can to avoid going backwards.

While the outlook is not what I would like, it’s not all doom and gloom!  I don’t idle well.  I run best near the red line!  To that end, I dug through the R&D backlog and knocked out another 10 – 20 new module configurations.  I know I shouldn’t be doing that right now, but who can sit around and do nothing for this long?  Not me!  Many of these are what you might call “new classics”.  If you consider the “classics” as being those ground-breaking effects of the 60’s and 70’s, these new classics are mostly from the 80’s, 90’s, and early 2000’s.  There were a lot of great effects released in that timeframe and these will make very nice additions to some thin spots in our offering.  With these new modules, the number of effects we “compare to” in our offering will be over 350.  That is *a lot* of effects to choose from, all in rack format and built by hand here in Dallas to suit your needs.

That’s it for now.  I probably won’t send another update until after the holidays, when hopefully parts will become available and there will be more interesting news to report.  Until then, all the best to you and yours through the upcoming holiday season, and thank you for your continued interest in the world’s best selection of the best and most affordable rack effects available!

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.

Yes! It’s time for another new module. Our new Black Pearl module compares to the vintage Pearl CH-02 chorus. The music of the 80’s included many effects-laden guitar parts, with chorus being one of the most popular. It can make guitar (and other instrument) parts big and spacious, perfect for both 80’s pop and arena rock. If it hadn’t been the 80’s, a time of fun and excess, some might say that chorus was perhaps a bit over-used, and often used in an over-the-top manner with high levels of modulation and depth. Perhaps, but it certainly contributed to a great deal of good music that is still popular decades, and generations, later.

Perhaps that over-the-top chorus doesn’t really fit in with today’s music, or even classic rock, blues, country, jazz, and grunge of any time. In that case, you need a “sensible” chorus. The Pearl chorus, and our Black Pearl module, may be just the chorus you’re looking for. It won’t take you into the seasick or spacey zones. All the settings of Speed and Depth are very usable and provide a range from subtle to deep. A Tone control on the wet path gives you the ability to tweak the color a modest amount. The Mix control gives you everything from the lightest hint of chorus at one extreme, “normal” chorus in the middle, and a vibrato-like effect at the other extreme where the dry signal is mostly removed. The Pearl chorus was much loved by those that knew of it during its production years, and is still a sought-after used pedal today because of its great “no nonsense” effect delivery.

We have several additional new modules that are ready to go, and we’ll be announcing them in Q1. Now don’t go looking through our website for them and getting ahead of our announcements! We have somewhere around 230 module configurations listed, comparing to around 260 pedals, so that would be a lot to sort through :^)
