Hello Effects Fans!

It has been a while since my Jan 31 update, in which I announced that we stopped taking new orders for a while until the COVID situation and the pieces of the economy that impact us improve.  We’re hoping that the ongoing vaccination programs will help, but still cannot predict when we’ll be ready to fully open up for orders again - so no news on that front.

If you have been watching, you’ve seen a steady stream of new module announcements as we continue to clear out the work we had in progress.  We just put out the announcement of our AstroFuzz module this morning.  That is the last of the modules we had in our queue, but it is a great one – one of our favorites.  There won’t be any more new module announcements for a while.  We still have a long list of new modules we are itching to start on, but we really have to stick to our “pause” plan for a while.  We’ll still probably bend the plan a little bit to sneak in tiny bits of R&D time here and there so we won’t be starting with an empty queue when we “resume”.  But don’t tell anyone.

We also had some other products besides new modules that were making slow progress in our R&D queue before the pause.  One of them is our “Naked Pedals”, which we also announced today.  These are pedals we sometimes build to try out a new effect circuit.  Once we build them, we have no further use for them.  We are now offering them for sale, even during our pause.  Check them out.  Just search for Naked Pedals or look for them in the Products menu.

In addition to the Naked Pedals, we have another pedal-related product that we may make available in the next couple of months or so.  It is something a bit unusual, but we think it is very useful and complements our rack products nicely.  It bends our pause plan a bit more than we probably should, so we’re still considering whether we need to wait until we resume instead.

While we’re paused, we have only very limited time available for our normal activities.  However, if we can manage it, we hope to begin putting together some product videos.  Yes, you’re right – it’s about time!  With our unique way of building effects, along with the sheer volume of effects we offer (hundreds!), this is a gigantic activity for us that is going to take a long time to just catch up with the effects we already have.  We’ll probably know more about our plans for this in the summer, so maybe I’ll have news about that in my next update.

We had a brutal freeze here in Dallas a few weeks back, but the sun is shining and Spring has arrived.  It’s one of my favorite times of the year, the return of warm weather!  What I especially hope is that we’ll soon be hearing live music, both indoors and outdoors.  They say music is the soundtrack of life, and that’s really true for me.  This past year without live music has been sort of like those big “clunks” I used to get between (or during!) songs when my 8-track player switched tracks.  2020 was the year of the “clunk” for me.  But now the sun is shining, the pool is warming up, and the optimism of Spring is in the air!

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.
