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: The Prince

Published: 19 January 2020 19 January 2020

 

   

Hello Effects Fans!

Today we introduce The Prince flanger, which compares to the Boss BF-2 Flanger. Prince was one of the great musicians and entertainers of all times. He composed his own music, played all the instruments on some of his albums, wrote songs for and sponsored numerous other bands, won Oscar and Grammy awards, and even took on the big labels in the music industry. And, yes, so enraged Tipper Gore that albums now have to carry ratings reflecting someone's opinion of their content. He was also an accomplished guitarist, although that often went unnoticed among all his other talents. He was particular about his sound, and to the surprise of many, was able to achieve his funky, rock vibe with a collection of inexpensive Boss pedals. There's often a lot going on in his music, but the Boss BF-2 Flanger seemed to be one of his go-to pedals.

Prince wasn't the only player to use the BF-2. Many guitarists in the 80's used it, including Robert Smith of The Cure, David Byrne of The Talking Heads, Johnny Marr of The Smiths, and Billy Duffy of The Cult, as well as many other well-known players such as Ernie Isley, Jeff Beck, and Rory Gallagher.

The Boss BF-2 Flanger, was probably the most popular flanger upon its debut in 1980 and still remains popular to do this day. In spite of several cosmetic changes, the circuit stayed almost exactly the same from 1980 to 2001, when it was replaced by the BF-3. It was so popular that you probably know its sound, even if you don’t realize it, particularly if you listen to music from the 80’s. Not everyone thought it was the best flanger available, though. To some it could sound a bit harsh or metallic. The Prince has options you can select to change up the tone a bit, including reducing the harshness, reducing the noise, and increasing the “swoosh” by chopping the delay time in half. Like Prince, we like the original BF-2, but prefer the GT version with its available mods.

(PSSSTTT... Hey, Buddy! Yeah, you. Come over here. I wanna tell ya something. I heard GT has another great flanger in the works. Some might think it is approved by the American Dental Association, but it’s not... Just sayin’. Now be cool, and don’t go blabbin’ about it...)
