This device is one of those clever inventions that make you wonder why no one thought of it long ago. I've only used it for a week, but it seems sufficiently sturdy and works as advertised.

Here's my current pedalboard layout. Nutty, yes, but I like it. Notice the Oknobs on the vibrato (Rate) and delay (D-level) pedals to the left. Very handy. Reflective tape on the "pointer" wings of the Oknobs helps tell the difference between 9 o'clock and 3 o'clock.

We will never stop kneeling before the gods of Sonics but O-Knobs
definitely provide another really creative OPTION to pedal playing.

I use a classic Oknob to control the drive on an Indyguitarist modded Boss SD-1 super overdrive.

"The Option Knob is great. I use the classic model to adjust the delay time on my Digitech and Visual Sound H20 delay pedals. I have also been using one to adjust speed and/or depth on my Marshall Vibratrem. I use a boutique model to adjust the balance of the clean vs. distortion blend on my Voodoo Labs Sparkle Drive. They work great and allow me to make quick changes without taking my hands off of the guitar. Something tells me I am just at the tip of the iceberg for finding uses for the Option Knob..."

brilliant idea, i love the option knob. i use it on my delay and my loop station. i've always wondered why nobody had come up with this idea before,i always wanted something like this!!

I use the option knob on three pedals, my favorite is in my MXR Phase 90, has an interesting probabilities allows me to have real-time control of my sound, it's very experimental¡¡¡¡

On the Tr-2 from Boss it is very useful, without a need to kneel down for set the rate.

And of Course my Digital Delay, someone mark a difference when you set the delay on time on a performance.

Option Knob is always with me, a new inovation for an experimental, dared, guitar or bass player.
You have to do it¡¡

Here is a photo of my pedalboard. I play with a country band in and around houston tx called "Lonely Road". I love my option knobs and the freedom i have with them, i use it most to blend in and out my #1 echo.

I received the optionknob classic. A very nice product.Very sturdy and great bang for your buck.Currently I’m using it on a Boss DD5 to control delay level. A much better solution than a "third hand" pedal.(I hear they are crappily made) or an old EH Hot Foot. Good luck with your product. I’ll be spreadin" da word.

I was just sitting one day thinking there should have been a way to control the knobs on my guitar pedals with my feet instead of having to bend down to the floor all the time. And I searched the internet to see if anybody else had thought of that, and, guess what; you guys had! The option knob is ingenious (like I would have invented it myself..)! I bought three of them for now, and I might be buying more later. Thanks for a great product!

It is definitely the simplest way for the stomp box gang
to expand expression of the sound.
I'm using an Option Knob for my ATD/First Act V-Stack Classic to adjust the amount
of its gain("Drive") level.
I used 2 V-Stack Classic stomp boxes for both a crunch rhythm sound and a lead sound.
Now I have one with an Option Knob!
I'm even looking forward to the Knob with a LED glowing!!!!!

Twisting and turning my toes now learning
To do what my fingers did
Lost my old knob, The "O" does the job
Melts face and blows off yer lid

No bending over, my soul's controller
The idea I wish I had had
For this here invention, I know it is destined
For pedals across the land

Option Knob, you are a treat.

Im grateful for this amazing tool. Extremely easy fit on any pot shaft, The strongest man made material I have ever seen. No worries, it does not protrude and is 1000x better than a mechanical exp pedal that would take up a lot of space on the board. You can drive the knob like a steering wheel. I really like that. Thanks for making this.

I am using the classic option knob on the Ibanez analog delay and the Boss DD-5 delay.Thanks again! What a great tool....

I use a Boutique Oknob for the volume on my YC-20 Yamaha for fast and easy volume sweeps while my foot controls my wah wah level... For guitar I use Oknobs with my DD-3 on the Feedback setting to unleash chaos -or- on the D.Time to dial in real-time, on my TR-2 to be active with the rate of tremolo, on my moded Small Stone to mangle modulation, and on my RC-20 in place of the Phrase Selector knob so I can switch between pre-recorded or blank loop banks...
