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: Nachos

Published: 28 March 2021 28 March 2021

 

 

Hello, Effects Fans!

Today we announce our new Nachos module.  It compares to the EHX Hot Tubes.  The EHX Hot Tubes pedal was released in the mid to late 70's.  There are two very different versions of the pedal.  One used two 12AX7 tubes.  The other used CMOS chips instead of tubes.  Both are good pedals, but for this module, we're focused on the CMOS chip version, which should maybe have been named Hot Chips instead of Hot Tubes.  Our Nachos module compares to the CMOS chip version of the Hot Tubes.  Fans of Sonic Youth were driving up the price of the original old pedals, but EHX has recently re-issued a new version in their Nano line of pedals.  The original may have also been used occasionally by SRV, although he probably never recorded with it.

The circuit uses an inverter chip to produce its distortion.  That makes it a "tone cousin" to our BuzzDrive module, which has configurations that compare to the Way Huge Red Llama, Mad Professor Stone Grey Distortion, and Way Huge Fat Sandwich, among others.  All these circuits get their flavor of distortion from inverter chips.  Somehow, inverter distortion can remain articulate with good note definition, even when it is cranked up.  It can also handle more bass than usual without getting muddy, making inverter-based circuits a good choice for bass players.  While these circuits are usually labelled as "distortion", they often top out and run best in the overdrive range.  At low drive settings, the circuit is pretty clean.  And at max drive, it is still more overdrive than distortion.  The Volume will let you drive things pretty hard further along in your chain, which causes it to seem to contribute to the module's distortion, but it doesn't.  It's just abusing whatever comes next in your chain.  Your guitar volume helps provide some control on both the volume and the level of overdrive.

The Nachos module stays true to the simple original.  There are the basic controls for the level of drive and volume.  There is also a Tone control, but it can be bypassed with the Tone Bypass switch.  We left off the direct output of the original.

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