The bottom dimensions are 86mm x 139mm. Yup, it's a golden rectangle! The height of the pedal at it's highest point is 75mm.

Our enclosures were designed to work well with other pedals despite being a bit larger. They will fit perfectly on a Nano size pedalboard!

All kcFX pedals come shipped with rubber feet with integrated screws that can be removed by merely turning them with your fingers. If you want to velcro your pedal all you have to do is remove the rubber feet and then replace them with the included countersunk screws. Store the rubber feet in that little envelope so you don't lose them!

Ah, yes, this is a good question. While the modern digital switch mode power supplies are convenient some of them can be noisy in certain situations. Also, you'll notice different playing feels with different power supplies. We like the One Spot a lot. It has none of that high frequency whine. In fact, my favorite response comes from daisy-chaining all of my pedals from one One Spot adapter. Isolated power supply taps for each pedal aren't always necessary nor do they always improve the response.

Turn it up until it's too loud. Then back off a little bit.

Groovy Wizard Fuzz Driver

Answer, tips, techniques!

With 18 volts Groovy Wizard is louder, punchier, with more potential clean headroom. It was designed for 18 volts so definitely make sure you try it at 18 volts. However, it works just fine on 9 volts as well (or any voltage between 5 volts and 18 volts, really). You'll get a bit less output and a more saturated sound.

Groovy Wizard was designed and optimized to take advantage of higher voltage levels. Running fuzz pedals on batteries gives a warmer response with smoother harmonics and a more elastic playing feel. So, using two batteries gives you the advantages of batteries and high voltages. Plus, you can use those old batteries you have laying around that are too weak to run some of your other gadgets. For example, if you had two batteries with 6 volts left, you'd get a nice 12 volts for your Groovy Wizard. And what does that mean? A very happy Groovy Wizard.

Electric guitars. Any electric guitar with passive pickups, high output or low output, will work fabulous with Groovy Wizard.

This is intentional as adding an LED to fuzz circuits can have a negative affect on its dynamics, touch-sensitivity and tone. Groovy Wizard was designed to have no sonic compromises and to maximize its dynamic response. To this end, other commonly employed circuit elements are also intentionally omitted, such as input "pull down resistors", which also negatively affect its touch-sensitivity.

Let me guess - you played a chord and while it was still ringing you reached down and twisted the Contour or Presence knobs and didn't notice much happening. The two tone controls are intended to be fine-tuning controls. We recommend setting them to noon and then just forgetting about them until you get to know the pedal and start wishing for slight tone modifications. But here's a good way to immediately hear what they are doing: For the Presence control, continuously play the high E and B string together while sweeping the control. You should hear the control sweeping through the upper presence frequencies. For the Contour control, continuously play the low E string with a slight bit of palm muting while turning the control. You'll hear how the bottom gets thicker or thinner. Another thing to try is set both to their extremes - Set the Presence at maximum and set Contour to minimum. Play a bit. Now set Presence to minimum and Contour to maximum. Play a bit more. Once you really get to know Groovy Wizard, I trust you'll appreciate the subtle fine-control you have over the frequencies.

What do you mean? African or European swallow?


Insights, tips, hints!

Nowhere! Tremdriver does not use batteries. Power it up with any standard center-negative 9 volt power supply. Internally, Tremdriver converts that 9 volts into a burly 24 volts voiced for optimum sound + response.

Tremdriver was specifically designed to go towards the end of your signal chain. It will embiggify all the pedals before it and give you precise control over how hard your pedalboard hits your amp. Typically the pedals that make sense to go after Tremdriver would be reverbs, delays, and buffer type pedals.

No. Tremdriver's harmonic tremolo function works by modulating the parallel preamp stages. If you turned the preamp off there would be nothing to modulate.

Tremdriver will definitely get you laid.
