Hello Effects Fans!

It has been pretty quiet here since my last update, as expected, but not silent!  Earlier today we announced our new 3U Pedal Rack and our new Double Looper configurations.  These two offerings are designed to make migrations to our rack solutions easier, providing more and better ways to continue using your third party rack effects and pedals in an all-rack solution. 

Our status hasn’t really changed much.  You are probably aware that there are some serious supply chain problems in the electronics world.  Those shortages are affecting the availability of many end products from appliances to automobiles, to, yes, Gerlt Technologies rack effects.  We are simply unable to get some critical parts right now.  Projected back order dates come and go with no new parts becoming available.  For us, these are simple, but critical parts used in our circuits.  They haven’t stopped making them or anything like that.  It’s just that they aren’t able to make enough of them fast enough with staff, facilities, and transportation that continue to be impacted by COVID all over the world.  Of course, the small supplies that are made are going to The Big Guys first.  It will be a while before availability trickles down to smaller companies.  That’s just the laws of supply and demand in action.  It will eventually get sorted out, but in the meantime small manufacturers like Gerlt Technologies will just have to wait.  That’s why we stopped taking orders earlier this year.  We plan to be a survivor, not a casualty, of the COVID aftermath.  I still don’t know when we’ll be able to restart, but some of our latest backorder dates for parts will almost certainly push a restart into early next year.

The best news is that live music is back!  Every day I see more and more info about tours and local shows.  I hope that all you professional and gigging musicians are getting more bookings – we’ve missed you!  For all of us that don’t play publicly, COVID has been a nasty reminder about taking our lifestyles for granted, as has been the passing of some great musicians like Dusty Hill and Charlie Watts.  Enjoy your favorite music live (and safely) when you can!

We appreciate your patience with us during our temporary shutdown.  Once things are back to “normal enough”, we’ll be ready to do what we can to earn your business and get you into some excellent rack effects.

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.
