If you’re one of those players who just have a couple of settings they need out of their expression pedal, and want to save space on their pedalboards, you should check out the new Electro-Harmonix Cntl Knob. The unit allows players extra control over any effect pedal that has an expression pedal input, by offering two presets. If this sounds like something you’re interested in, read on.
Electro-Harmonix Cntl Knob
The new EHX Cntl Knob essentially substitutes your expression pedal with two preset values, which represent two positions of your expression pedal. If your pedalboard is a little cramped and you don’t require the ‘sweep’ of a traditional expression pedal, this handy little unit might be just what you need.
The two EXP knobs mimic two preset ‘cocked expression pedals’. Fully counter-clockwise, the knobs correspond to the heel position, while clockwise they correspond to the toe-position. So if you have a couple of favourite positions on your expression pedal, you could use the knobs to dial them in and forget about them. Then you can always get back to them whenever you want, without looking for that ‘sweet spot’ every time. For example, you could store two different pitches on a pitch shifter, or feedback levels on a delay pedal.
It’s a simple concept in practise, but this diminutive little pedal could actually be very practical. The unit has a TRS+/- Button on the side to ensure compatibility with pedals by all makers and comes with a 6-foot TRS cable included in the price.
You can see the Cntl Knob in action in the official demo video below. It definitely looks like a useful bit of gear for cramped pedalboards, and at this price, is also a bit of a bargain if you need a basic expression control for your setup.
