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, Everyone - We're back! Welcome to a brand new decade! We’re kicking it off with a new module announcement today.

For some reason, there are a few great Maxon effects that players in the USA may have missed. The Maxon DS-830 Distortion Master is one of them. Our GT-830 compares to this largely undiscovered pedal. The individual sections of the circuit are generally unremarkable in design, including input and output buffers and silicon diodes in both hard and soft clipping configurations. But there is a unique active tone stack providing independent Bass and Treble controls with a wide range of effect. The overall tone purposely highlights the low end, and tends to be a little warm and dark, especially when the Gain is low. It is meant to provide a solid bottom and some fat. The Gain provides a wide range, from almost clean, through overdrive, and into distortion. With the GT More Gain option, the Gain range extends well into hair metal tones, with plenty of touch, feedback, and harmonics. The Gain cleans up pretty well with the guitar volume, but don’t expect pristine cleans at any settings. The gain is enough to hit the front end of your amp or downstream pedals pretty hard, enabling amp break-up or meltdown, should you choose it. The character of the gain is somewhat Marshall-like, although clipping diode selection can change it up.

Since it is designed to fatten up the tone and provide a nice tight bottom, the circuit can sound dark, particularly with humbuckers. The wide range of active tone control will counter that, but even the tone stack is purposely skewed a little to provide more control over the lows than highs. The stock silicon clipping diodes are good, but red LEDs and no clipping diodes at all both yield brighter tones, although the character of the distortion also changes. In other words, clipping options are worth considering, maybe even more so for humbuckers than single coils. If you already have a bass-heavy tone, this may give you some good shaping options or push you into the Dark Side. If your tone is a bit thin or bright, this can give you some nice bottom end to fill things out a bit. Fat-bottom tone makes the rockin’ world go ‘round!
