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!

Hello, Effects Fans!

Today we announce our new Brick Boost module.  The Brick Boost compares to the Pete Cornish ST-2 boost.  Pete Cornish built one into David Gilmour's custom pedal board that was used for The Wall.  It is almost a direct clone of the Colorsound Power Boost, but with some enhancements.  David Gilmour has used the Power Boost for decades to produce his signature singing, fuzzy, overdrive tone.  If you've been using a Power Boost to get those Wall tones but you aren't quite there, this may be that little nudge that helps close the gap.

The Brick Boost has the extra buffer, an extra gain stage, and some slight parts changes that set the ST-2 apart from the original Power Boost.  The original Power Boost ran at 18V, providing loads of clean boost.  The ST-2 and Brick Boost run at 9V.  That greatly reduces the headroom, which should lead to earlier breakup and a bit more grit.  The extra gain stage that is added should also contribute to a bit more dirt at lower volumes.  In addition to the Brick Boost, we already have our Color Bomb, which compares to the original Power Boost, as well as our Color Drive, which compares to the closely related Colorsound Overdriver.  The Color Driive also runs at 9V, but doesn't have the extra gain stage of the Brick Boost.

You can see more details about our Brick Boost module at: Brick Boost.  Or look for it in the Boost Modules section under Products -> Modules -> Modules By Type.
