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 Configuration: VibraChorus CS-505

Published: 06 September 2019 06 September 2019

 

Today GT announces a new configuration of our VibraChorus rack chorus effect module, the CS-505. This configuration compares to the Maxon Insta-Chorus CS-505 and Ibanez CS-505 Chorus pedals. The Maxon and Ibanez versions were identical internally – only the enclosure was different. Maxon built both of them, of course, just as they did many other Ibanez-branded pedals.

The CS-505 is similar to the Boss CE-2, similar enough we use some of the same boards to build them. But they sound quite different. The CS-505 doesn’t get into the spacey, sea-sick warble you can dial in on the CE-2 and many other chorus units. All the settings on the CS-505 are useful and sound great. While it doesn’t give you the over-the-top chorus effect, it does give a deep, clean, thick chorus. If you are looking for a good solid 80’s chorus that is simple to use, and you don’t need to go over the top spacey, then the CS-505 config may be a good choice. You might even consider it for an "always on" effect. We’ve been looking into some of the great vintage chorus effects lately, and this one was a stand-out. You’ll probably see a couple more chorus offerings in the months to come!

You can find more details about the VibraChorus CS-505 at VibraChorus

You can also check out the CS-505 at the upcoming Amigo Guitar Show in Ft Worth on Oct 5 and 6. We’ll be there with our Big Stack of rack effect modules for you to try out. Stop by and play!
