August 21, 2006
Guyatone wah and optical tremolo
Kevin Bolembach, president of Godlyke Distribution (parent company for Guyatone), gives a thorough demoing of the company's brand new GST-UO5 Ultron Auto Wah. The Ultron, Kevin says, is basically a tricked-out tribute to the Mu-Tron III envelope filter. The Ultron has an all-analog audio path with digital controllers for added flexibility. The Ultron features six effects mode, expression pedal jack, threshold, peak level, and frequency controls, control switch, true-bypass effect switch, range, drive, and tap/pedal setup switches, optical circuitry, and more. Kevin also introduces the GST-C04 Ultrem Optical Tremolo. The Ultrem features six effect modes, depth, speed, and saturation controls, expression pedal jack, control switch, true-bypass effect switch, pan on/off switch, blend on/off switch, tap/pedal setup switch, and more.

PROMO GIRLS: You're watching Gearwire.Com.

KEVIN BOLEMBACH: Hi everybody. My name is Kevin. I'm the president of Godlyke Incorporated. We're a distributor for many of the top boutique effect lines in the United States, Maxon, Guyatone, Big Sonic, several other companies.

And a couple of years ago, Guyatone decided to develop several very high-end professional quality effect pedals that were analog-digital hybrids, so the audio is 100% analog but using digital controllers were able to achieve a lot of the effects that other companies use POD digital modeling for but in an analog realm. So, after several years of research and development, we're finally showing the pedals at this years Summer NAMM Show, and they are sitting right here: the Guyatone Ultron Envelope Filter and Ultrem Optical Tremolo.

so, both these units use photocouplers, which is a type of optical circuitry that was prevalent in a lot of units in the '70s, envelope filters, phase shifters, and tremolos. Some of the best amp tremolos of all time use the optical circuitry, and envelope filters, the classic Neutron 3, which pretty much everybody from Bootsy Collins to Flea have used on records, use optical circuitry as well.

So, what you have here is, for all intents and purposes, a tricked out Neutron 3 with four different filter types, three different filter ranges, peak and threshold controls just like a standard Neutron. In addition to this, this has a digital CPU controller that offers oscillator control of the envelope filter as well with six different waveforms, tap tempo, and expression pedal control over several different parameters.

So, what I'm going to take you through is just a couple the settings real quick. The initial setting which is envelope filter.

But the interesting about this is each mode has a sub mode, so for example in envelop filter mode I can also toggle into oscillator mode by stepping on this controller switch right here. So, I meant --

It adds some very interesting new types of effects that you can do on the fly, toggling between basically an auto wah and an envelope filter wah. In addition to that, you can scroll through several different effect modes here. If you're in oscillator mode, you have tap tempo control on the filter so you can sync in to song tempos. You can also control that in BPM or milliseconds so you can sync with digital devices in real time and make sure that the syncing is absolutely accurate. In addition, there's also a wah, standard wah wah pedal control of the filter...

...that you can then tap into envelope filter mode. You can also control the unit's tap setting...

...with the expression pedal so you can...

...fade into the effect, tapping into --

You can tap and toggle between the two basically, depth control and envelope filter control. The last two settings control the rate of the unit, so you can adjust the speed of the oscillator with the foot pedal, and you can toggle it to envelope filter mode.

And so that's basically the filter control, and the tremolo is basically the same thing with the addition of a saturation, which is an overdrive, and the ability to pan between two amps. And the trem is really designed for guitar but the two units also, because of the digital aspect where the oscillators work in -- if you set a tempo, it's in absolute tempo, you can sync the two units together and do all types of rhythmic variation using the two units. And basically with this, you open up a type of, you know, area of filtering or tremolo effects. Now, before this, they weren't really available from an analog device and that's pretty much the units. They're shipping now off our web site, godlyke.com. You can buy them direct and I don't know, that's it.
