 What We Do

You know them as guitar pedals

We build them as rack effect modules you can customize to get Your Tone

Put several rack effect modules into a 3U rack enclosure

Connect power and audio on the back like guitar pedals, adding connections for remote switching

Add a remote footswitch unit to turn rack effects on and off

Add as many rack effect modules, enclosures, and third party products as you like. Plug in your guitar and amp. Rock it! It's that simple.

Hello, Effects Fans!

I hope 2020 is off to a great start for you!  We’re certainly going full speed, but I wanted to take a few minutes to let you know what we’re up to.

Through January and February, you’ll see new module announcements about every couple of weeks.  We have phaser, flanger, chorus, and cool bass modules coming in that timeframe.  We also have another four modules about halfway through the R&D process.  We should have boards for them later this month.  We expect those module releases will follow in March and April.  They will bring our total number of module configurations to somewhere around 235+, comparing to some 265+ guitar pedals you may know of.  We’ve been burning the midnight oil for the past several years to make sure that we have a wide selection of effects and customizations so that you can find Your Tone in our rack modules.  Making new modules available is a lot of fun, and we expect that will always continue.  We still have a list of many dozens of additional modules that we want to develop, so we aren’t in danger of running out of new ideas anytime soon.  

Since we now have some reasonable depth and breadth to our module offering, we need to take a breather and spend some time on “other stuff” that seems to always be necessary in running a business.  We also have a long list of these items we need to address, but they tend to not be much fun and rarely get the attention they deserve.  One of those is our website.  It was put together pretty quickly, and was never finished.  Of course, websites are never finished, but even our initial website rollout wasn’t completed.  We have some content that was never published, as well as some content that needs some updates and polish.  And as you have probably noticed, we don’t have any demo videos.  I have just kicked off a major effort to address some of these issues.  Over the next 3 months or so this is going to be our main activity.  We’re still working out detailed plans and scope, but changes should start trickling out later in January.  

This temporary shift of focus won’t be as obvious now as it will be when we head into summer.  Since we will be stealing R&D time for the website work, our queue of new modules in R&D is almost certainly going to run dry for a little while.  I anticipate we’ll have fewer new module announcements for a while, beginning sometime in April and going into the summer.  But once the website project begins to wind down, we’ll start filling up the R&D queue again.

That’s The Plan.  We hope you’ll join us as we continue to make available affordable, custom rack effects with killer tone!
