Hello Effects Fans!

It seems like time for another update, but not much has changed.  The supply chain problems continue to make parts unavailable and there is no particularly believable plan or timeframe I know of for these problems to be resolved anytime soon.  Perhaps early next year?  Perhaps not? 

We lost another supplier that has been supplying boards to us for several years.  Luckily, there are other suppliers that can make our boards and we’re in the process of switching to one of them.  We’ll have to go through a testing and validation process with the new supplier to make sure there are no technical glitches in getting our specs to them and that their results will meet our quality standards.  This takes some time, but we should have that resolved before parts become available.

I’m concerned that more parts may become unavailable if the supply chain problems continue.  Available stocks are being depleted.  I’m also concerned that demand for dwindling supplies, as well as the increasing cost of energy and transportation, along with high inflation, will force us to have to raise prices to cover the increased costs.  Shipping costs have always been an issue, but are now often higher than the cost of the items being shipped.  That represents a significant overall cost increase.  If you’ve been following us, you know that providing the best selection of the best rack effects is our mission.  But you will also have seen our frequent use of the word “affordable” in our objective.  It’s not difficult to make expensive things that few can afford.  We want our rack effects to cost no more than pedals, less when possible.  We’re nearly there and will do everything we can to avoid going backwards.

While the outlook is not what I would like, it’s not all doom and gloom!  I don’t idle well.  I run best near the red line!  To that end, I dug through the R&D backlog and knocked out another 10 – 20 new module configurations.  I know I shouldn’t be doing that right now, but who can sit around and do nothing for this long?  Not me!  Many of these are what you might call “new classics”.  If you consider the “classics” as being those ground-breaking effects of the 60’s and 70’s, these new classics are mostly from the 80’s, 90’s, and early 2000’s.  There were a lot of great effects released in that timeframe and these will make very nice additions to some thin spots in our offering.  With these new modules, the number of effects we “compare to” in our offering will be over 350.  That is *a lot* of effects to choose from, all in rack format and built by hand here in Dallas to suit your needs.

That’s it for now.  I probably won’t send another update until after the holidays, when hopefully parts will become available and there will be more interesting news to report.  Until then, all the best to you and yours through the upcoming holiday season, and thank you for your continued interest in the world’s best selection of the best and most affordable rack effects available!

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.
