Description

For pro expression control in a compact package, there’s no better choice than the BOSS EV-30. Its small footprint is perfectly suited for cramped pedalboards, while the die-cast aluminium chassis offers a rock-solid foundation and BOSS’s famous rugged reliability. A key feature of the EV-30 is an innovative internal mechanism that provides ultra-smooth feel and precise parameter control, delivering performance that rivals full-size pedals. And with two expression outputs, you can save further space by controlling two different devices from a single pedal. The outputs are electronically isolated, eliminating the possibility of noise issues from ground loops. The EV-30 brings powerful real-time parameter control to the many BOSS compact pedals equipped with expression pedal inputs. It’s also ideal for use with BOSS multi-effects processors and effects switching systems. A handy polarity switch provides compatibility with a wide range of music gear, allowing you to use the EV-30 with most devices that support expression control.

A solid, well-built pedal
Pattern Name: Single
I bought this as a wah pedal for my Boss Katana 100 MkII. It's made out of aluminum and a LOT more solid and heavy than many reviews seemed to imply. It COULD be a few inches longer to fit under my shoe, but as it is it's completely workable. It also works as a volume pedal, and has two outputs -- one for volume, one for other uses. I'm very pleased with this! ... show more

A high quality pedal that's compact in size
Pattern Name: Single
On my Boss Katana 50 G3 modeling amp, it not only works as a very nice high quality expression pedal, but when not assigned for that, it also works as an amp output volume control. That's an added feature I wasn't expecting. It has a nice adjustable balanced foot feel to it and stays where you leave it. ... show more

Rugged Filter Pedal for Synthesizer
Pattern Name: Single
This is a great expression pedal, it’s precise and well built—it has the perfect heft where it wont move around accidentally but also won’t be a huge burden in a backpack. The stiffness is just right for keyboard use. Having 2 outputs is also a plus, but I have no need for it as of now. I use it as a filter control pedal for an analog synthesizer (Prophet-10). The included right angle cable is okay, but it is very short. In a seated position, the cable is the perfect length, but for a standing position (i.e. for gigs), the cable gets pulled taught and I cant have the pedal as close to me as I’d like. Normally, this wouldn’t be an issue, and I understand this is intended for use with pedalboards, but for a $100+ pedal that only acts as a controller/modulator, the cable leaves a lot to be desired. One great feature is that you can reverse the polarity for each output, and you can individually control the minimum values for each output as well. The footprint is smaller than it seems which makes it great for portability. ... show more

Works great with all of my guitar pedals that have expression ports!
Pattern Name: Single
I recently got two guitar pedal that had expression ports: The Empress EchoSystem and the Electro-Harmonix Pitchfork+. After checking out reviews for expression pedals, I opted for the Boss and am very happy I did. It pairs beautifully with both of my guitar pedals, with the full expression for both pedals changing smoothly with the full range of motion on the pedal. This pedal is built like a tank and you can pair two different pedals with it. I like the size. It's small enough to not take up too much real estate but big enough that it feels natural to move it with my size 10 foot. ... show more

Moog Muse
Pattern Name: Single
I ordered this to use with my MPC.. and it works fantastic! It is very solid.. very heavy.. has two outputs.. only needs a TRS cable, no power required. The zero can be set on each of the two expression ports, which are both controlled simultaneously with the one pedal. Of course you would need two TRS cables. Attention Moog Muse owners.. this does NOT work with the Muse.. amazingly, it does work with some other Moog stuff though.. I ended up plugging it into my Matriarch, and then sending CV from it to the Muse, And it can work that way. But straight into the Muse.. nope. Has to do with the digital translation in the brain of The Muse or something.. you are welcome!. ... show more

Awesome pedal
Pattern Name: Single
I really did my research on this expression pedal and it’s better than expected very well built and durable. Aluminum construction so it stays where you put it. Has a thick powder coating. Dual feature is awesome. I’m using it with a reverb and delay. Would recommend this pedal
