Ever wanted to build your own fully-analog multi-wave tremolo? We got you! Our Knight School Trem kit gives you what you need to build a fully-customizable tremolo pedal that goes far beyond the norm. Featuring two different modes and a waveform Warp knob, you can dial in anything from two types of sawtooth waves and a triangle wave to an adjustable pulse-width square wave with the flick of a switch and the twist of a knob. Tired of trem pedals that are either too fast or too slow? The Knight School Trem gives you the best of both worlds with a super-wide range modulator that won’t leave you wanting more. Add in an adjustable depth control and you’ve got a super full-featured trem that does exactly what you want, and built with your own hands!

While most guitarists recognize the word “transistor” as the fundamental effects pedal amplification parts, they have several other functions depending on how they’re wired. One such function is that of a switch. When voltage is applied to the base pin of a transistor, it “opens” the switch, i.e. connects the other two pins together.

This is how Boss and Ibanez’s bypass switching works, in a nutshell. But what if a pedal’s input signal was connected to a transistor’s collector, and the transistor emitter was connected to ground? When voltage is applied to the transistor base, the signal gets dumped to ground. When the voltage is cut, the signal passes through. Now, what if you could find a way to send a rhythmic positive voltage to that transistor base? It would rhythmically modulate the signal. Uh-oh, this sounds like tremolo!

Of course, there are many ways to achieve this effect, but this is one best suited to DIY. The crudest form of this effect was first developed by Jordan Electronics with their Vico Vibe plug-in unit that definitely does the thing I just described but the LFO’s speed range isn’t so hot and only does one waveform. BO-RING!

Our Knight School Trem gives you SIX distinct waveforms, a huge speed range control, a depth control and an LED rate indicator that mimics the selected waveform, all in an easy-to-build fully-analog package. Let’s go!
