Strum freely:The nice thing about this type of knob is that it's fairly reliable and easy to adjust.They will sit on your guitar just as the original one,work with a more tactile knob like this will cause no awkward feeling to jam your inspiration.When they located in your strum path,you can roll with them at performing and create amazing rhythm freely.
Smooth rotary:Knobs have a good weight with quality texture,a polished surface that feels great between thumb and forefinger.Provides accurate and fine-grained control.You don’t need to crank them down too hard to prevent the knob from slipping when hitting either end of the pot's rotation,they can make your button more cozy to the hand or foot.
Add personality:If you had an old amp in the closet missing a few knobs,apply these will bring the amp back to life and give it a little more personality.Even it is not be directly getting the touch impression,people walking around your gear will get a really nice impression as each of them passes in front of all your knobs in the viewers perspective.
Quality plastic:They are strong and easily fit on the potentiometers.Great little knobs with well made hardware and machining,no burrs to block the threads.Other knobs might be driving you nuts since the tiny unsteady stem knobs on the instruments.Even if you don't have especially big fingers,the thick solid stem on these knobs can be a breeze for you to adjust.
Multi-Function:Great to use for replacement or emphasis knob recognition.Come in handy for building guitar effects and restoring old recording equipment.Very cool way to customize your pedals,replace the knobs on an old fuzz pedal with these!Or use these to finish off a diy synth that had a effects with similar knobs,they just make almost any gear you put them on look more professional.
