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 FuzzFazer module.  Our FuzzFazer module compares to the Roland AP-7 Jet Phaser.  The Roland AP-7 Jet Phaser is a classic vintage phaser that combined a fuzz and phaser into an early multi-effect unit.  It was used to get that funky guitar sound in The Isley Brother's hit Who's That Lady?  Also works great with bass, and was used by bass slapper Larry Graham with Sly and the Family Stone and many of his other collaborations, including with Prince.  It was available around 1975 - 1978.  Funk it up!  While it wasn't used by Keith, it gives you a nice tone for the Some Girls album. 

The sound wasn't the only funky feature of the Jet Phaser.  The controls on the original unit were a bit funky.  There was a Jet Level that controlled the volume, but only when the fuzz was on.  A Resonance knob controlled feedback in the phaser portion of the circuit.  A Slow Rate knob let you adjust the rate of the phasing, when it was on the Slow setting.  There was a footswitch to turn the effect on and off.  A second footswitch changed between Fast and Slow phaser settings.  Then there was the Mode switch.  You could switch between six different modes.  The first four modes were combinations of bright/dark fuzz and two phaser presets.  The other two modes had no fuzz.  They were phaser-only settings.

Our module stays close to the original pedal design, but we changed up the controls to provide a wider array of settings than the original six modes.  The original modes are all still there in the new controls, though.  The original also had a fixed tone stack for the fuzz circuit, which offered only "dark" or "bright" settings in the four modes that had fuzz.  We've replaced that with a simple Tone control.  At the two extreme positions of the knob, you get the old tone settings, but with much finer control in between them.  Four of the original modes were fuzz plus phaser and two were phaser only.  But you couldn't get just the fuzz without the phaser.  Our controls allow that.

We offer a number of control options for our FuzzFazer.  We leave the base tone alone and just allow you to dial in more of it.
