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 AstroFuzz module.  The AstroFuzz compares to the AstroTone Fuzz, Sam Ash Fuzzz Boxx, and Analogman AstroTone.  There was also a recent re-issue of the Sam Ash Fuzzz Boxx, which sadly seems to be about as rare as the original units. 

The opening riff in Elton John's Saturday Night's Alright has one of the classic 70's guitar tones.  It gets better every time you hear it!  If you haven't heard that tune in a while, head over to YouTube right now and give it a play.  We'll wait...

Did you also play The Bitch Is Back and Tiny Dancer while you were at it?  OK, we'll wait again...

OK.  That's better.  It isn't certain whether Davey Johnstone used an AstroTone Fuzz for Saturday Night's Alright, but many believe he did and it sounds exactly like it, whether he did or not.  While it is called a fuzz, it is more of a high-gain overdrive that maintains its clarity and articulation, without being too compressed.  It's a very open tone that begs for the volume to be cranked up.  More.  It is addictive and could easily become a key component of your tone.  Buffalo Springfield's Mr Soul, Neil Young's Cinnamon Girl, and some Boston tunes might also be dialed in.  In addition to classic rock and pop, it is excellent for blues and country.  It also handles bass better than most high-gain overdrive and fuzz pedals.  We like it served straight up, but it should also be a good effect for stacking.  Would love to try it in front of a hot Hiwatt, with a bit of windmilling on a P-90 SG, but don't have a P-90 SG...  yet...  If you have a clean-tone song that needs a little something more, a light dose of this might be just what you're looking for.

The AstroFuzz has quickly become one of our favorite modules.  It's as good as beer.  We keep to the original tone and design, but have a couple of options worth considering.

Such a classy, sassy tone and very fun to play.  It definitely puts a smile on your face!  It's like a time machine back to fun summer days of the mid-70's, rockin' that AM radio with Elton John, bell bottoms, and a cherry Kool-Pop while playing Jarts!
