While multi-effects units continue to grow in popularity and capabilities, at the shop we are all still dedicated "pedalboard guys." The range of choices and options in individual effects is simply too attractive to pass up. As well as the ability change your mind, or assemble multiple boards for special purposes. 

But assembling a pedalboard can be choice overload, and can also get pretty expensive. The Walrus Audio Fundamental Series of effects are a great starting point (or destination) for putting together a reliable, high-quality effects setup. Then Fundamental Series covers all the "core" effects that anybody could want, and all are priced at just $99. Great for starting a new board, or where you need "that sound" for certain songs but don't want to spend big bucks. All Fundamental pedals run on 9VDC tip-negative power, and are designed and assembled by Walrus Audio in Oklahoma.

In the words of Walrus Audio on their Fundamental Tremolo pedal:

The Fundamental Tremolo is a classic optical tremolo, giving you that iconic chewy movement. With three wave shapes to select from, you can get sounds from smooth and soothing to glitchy, wild, and crazy.

Rate – The Rate slider sets how fast or slow the LFO is oscillating. A lower rate gives a gentle wavering texture, while a higher rate gives a shimmering and pulsating effect.

Depth – The Depth slider controls the strength of the tremolo effect. At a lower depth, the volume oscillations stay closer to the input for a more subtle movement. At a higher depth, the tremolo becomes more pronounced with the volume are greater.

Volume – The Volume slider sets the overall output volume of the pedal.

Slide Switch – The slide switch allows you to change between three distinct oscillator waveforms:

Sine: Sine gradually adds and decreases volume smoothly for an easy and subtle tremolo. Square: Much more pronounced than sine, square wave has a more on-off pattern. Random: Uses sample and hold that picks new random values at an interval set by the rate control.
