Description

The Mythical Overdrive is a low gain overdrive / boost based on the legendary Klon Centaur. Each MO is handmade in Oregon by Ken himself, and they just exude quality from the moment you pick one up. Made from quality components with several options for color, knobs, and clipping diodes allow you to customize the Mythical Overdrive to your liking.


Available in standard spec which helps tame brighter rigs and vintage spec built to get that Klon tone everyone wants but few can afford.


The 1N34 (germanium diodes) offers vintage clipping at lower gain settings - germanium diodes provide warm tube amp like breakup.  

The D9E (NOS Russian germanium diodes) offers vintage clipping at lower gain settings - germanium diodes provide warm tube amp like breakup.  

The OA126 - NOS German Telefunken Zener diode that clips at higher gain setting allowing for more headroom and an increased boost. Great low end breakup with clarity. Most popular Telefunken diode and almost extinct.

The OA128 - NOS German Telefunken ( silicon based ) clip at higher gain setting allowing for more headroom and an increased boost. Great compliment to the 1N34 providing more versatility when you really want to cook the preamp section of your amp

This is the pedal I was missing! I should have gotten an overdrive effects pedal long ago. I'm so glad I picked the Mystical Overdrive. The pedal provides a rich enhancement to the tone of my PRS McCarty 594 on either my Marshall 40V 8040 or Orange Crush 35RT. I can add even more sustain to the guitar with either a clean boost, overdrive, or distortion on a high gain setting. Ken was prompt and very helpful in answering any questions during the purchasing process. Thank you

Ken was excellent to deal with and communicated frequently until the pedal arrived. I ordered my MO right after Christmas so he emailed regularly to update me on shipping. Also, the pedal is amazing and will be a permanent staple on my board. Couldn’t recommend more!

I've got D9E/OA126 version of the pedal. I had to wait a bit for the delivery during Christmas/New Year holiday period, but nevertheless, the wait is over and the sonic feast could commence. I try to keep my effect chain simple and spare - and this pedal really does help. Clean boost sounds heavenly on its own and the overdrive stacked with EP type boost is The Sound. Excellent!

I am totally blown away with how good this pedal sounds. I needed a pedal that gave a significant boost (when required) as I use a 1967 Fender Super Twin which only breaks up at fairly high volumes. This overdrive pedal complements the amp beautifully, gives more than enough boost and the diodes (TelefunkenD9E/OA126) give two brilliant options. I did tons of research before choosing this pedal but am very happy with my decision. Being based in the UK I was relieved that Ken offered very prompt, international shipping. Thank you. I would highly recommend this pedal.

Best Klon clone I've played and really pushes through the mix with sweet tone. A new favorite pedal I'm keeping. Got the D9E and OA126 diodes.

I've now bought around three of these. Dare I say it's as good (if not better) than the original KLON which I also own. I recommend the OA126 valve.

Absolutely one of my favorite Klon types…probably my favorite. I especially love the OA126 version. I love the lower gain and rich tone it delivers. Top notch USA built quality. This is my 3rd MO. These are a must have for a klon fan.

Useful and great sounding pedal! I tried several other Klones and packed them up and sent them back. The MO is a total keeper! Great service and communication too.

In a sea of overdrives this MO is seriously a diamond in the rough. No other OD gives me the tone I want from my Strat's neck PU, or the PAF and P90 combo in my Tele. Just when I thought the MO couldn't bring me more joy, I tried stacking it with my Lightspeed and hooooboy the search for the tone I've had in my head for years is finally over (I swear). 1000% satisfied.

Amazing sound, if you don’t have it, you don’t know how your valve amp can sound. Buy it, this stuff is great. (Or not and you’ll always wonder, haha)

I owned a reasonable collection of top-end/boutique overdrive pedals, but this pedal has literally replaced them all—in fact, I’ve sold almost all of them in the past week. A great pedal, and one that feels like the end of a tonal quest for me. Now I’ve found my sound, I can focus on my playing instead.
