Hello Effects Fans!

In my last update I was excited after finding some small quantities of critical components that are needed to build our effects. I hoped that to be a sign that perhaps some of our supply chain problems were easing. But it seems those were just one-off lucky finds. I haven’t found any more since then. On top of all the other problems, we now have the ripple effect of the conflict in the Ukraine, which has caused even more parts to become unavailable and/or very expensive.

It’s one thing to be optimistic, but another to be unrealistic. This is no longer a time for simple optimism. It is a time for handling unpleasant realities. Our reality is that it seems very unlikely that enough positive changes will occur quickly enough for us to re-open in 2022. While the corporation is in a good position to weather a continued lengthy shutdown, the people are not able to. We need to take some time to go do “other stuff” for a while.

We still have several new modules to announce. The work is complete on almost all of them, so I’ll try to get those announcements out in April and May. Other than that, I’m afraid it is going to be pretty quiet here until we are able to reliably source parts at reasonable prices again. I probably won’t have another update until late summer or into autumn.

The good news is that Gerlt Technologies is still here and alive. We haven’t “lost” anything. We still have the largest selection of rack effects available, getting close to 400. Our effects still sound great. And we still want to make them available to you. We’re just going to have to continue our break for a while until the business and economic conditions improve to the point that we can provide outstanding products and support at affordable prices.

I apologize for the continued delay and will do everything I can to get us going again as soon as it becomes feasible.

 

Cheers,

Hello Effects Fans!

The new GT Mudslinger module is an original GT design that doesn’t compare directly to anything else that we know of. It is designed specifically for bass players. It isn’t really an effect itself. It’s more like “a secret sauce” that makes other effects better for bass. If you have tried effects with bass, you probably have found that many of them don’t really sound all that great. There’s something about the physics and human perception of low-frequency sounds that cause many effects to sound flabby, loose, or otherwise unusable with bass. Effects that add gain, such as overdrive, distortion, and fuzz in particular often sound unpleasant, although there are a few exceptions here and there.

The problem is with the lowest frequencies, typically somewhere around 80-200Hz. Not only do effects not handle that range gracefully, but they often reduce bass to minimize the problem. A reduction in bass, complicated with flabby sound, can cause the rhythm to get lost in the mix. You probably know that while the root bass notes are in that low-frequency danger zone for effects, each note is also accompanied by a lot of harmonic content well above that note’s frequency. Those harmonics give bass some definition, clarity, pop, and presence. Those harmonics are well above the danger zone.

The Mudslinger takes advantage of this fact. As your signal comes into the Mudslinger, it divides the low and high frequency content. You get three choices for that crossover frequency, as the best crossover may differ from one effect to another. The high content is routed to a loop, where it can be run through guitar effect modules, which might not normally sound good with bass, but sound great with guitar frequencies. The low notes go straight through, without effects, keeping your rhythm tight. Then the two paths are joined by a Mix control so you can adjust the dry lows and the highs with effects. The result is a somewhat lower level of effect, but without the flabbiness, looseness, and general silliness you sometimes get when you send bass through effects. And your root bass notes keep your bass line driving. We think it is the best of both worlds. The biggest benefit is that you can experiment with virtually any guitar effect, instead of limiting your selection to those few designed specifically for bass.

Buffers are added in the path to make sure the split signal doesn’t degrade, particularly the high path that might go through a lengthy chain of effects. We think this ranks the Mudslinger right up there with compressors and EQs on the bass “must try” list.

You can see the details about our Mudslinger at: Mudslinger.  Or look for it in the Bass Modules section under Products -> Modules -> Modules By Type.
