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: Digital Delay

Published: 17 July 2019 17 July 2019

 

 

New Digital Delay Modules!

Previously we announced our first Digital Delay module configuration, the Ocean Blue. Today we announce four additional Digital Delay modules: The DD, DD Plus, DD Deluxe, and DD Super Deluxe.

Our design for the Digital Delay module allows a wide choice of features and configurations to be selected. These new configurations, as well as the previously-released Ocean Blue configuration, are “standard” configurations that you can choose, or you can choose one of those configurations as a starting point for your own custom configuration.

These delays are based on the popular PT2399 digital delay chip. The PT2399 isn’t an expensive, high-end, crystal-clear chip like those found in proprietary brands of high-end digital delays. Like the old analog BBD delays it emulates, it comes with a bit of noise and even distortion depending on your control settings. It can be a relatively clean delay, but not pristine. Repeats will usually get progressively dirtier with many settings. There are many features available, including your choice of tone stacks, tails, tap tempo, max delay time, and modulation. We offer a large number of features and options so that you can select just the ones you prefer, or create a more versatile delay with lots of controls. With that many options, configs can get pricey, or even difficult to price. The configuration and option prices should help, but we may be able to help keep things affordable if it gets out of hand. These delays aren’t really intended to compare directly to any specific pedals. However, there are a number of PT2399-based delays available, which will be roughly comparable.
