BOSS EV 30 Dual Expression Pedal

Sam Bell indulges in a little self-expression, with the help of a newcomer from Boss.

For this issue I've been having fun with the latest Boss expression pedal. Boss has always been at the forefront with effect pedals and controllers for guitars and other instruments and now the company has released the EV30 dual expression pedal. This was a review I was definitely looking forward to!

An expression pedal is usually a foot controlled unit, not too dissimilar in appearance to a wah pedal. It can be linked to other pedals with an expression output to control features such as the volume, depth or rate of an effect and that's what the EV30 does: it can simultaneously control two effects. This gives the user the ability to control effects in real time with real ease. You could, for example, link a reverb and delay unit to this pedal and fade in and out various different degrees of the effects. You could then also turn one of the effects off or change a parameter of the chosen effect and go from there. The dual expression leaves the user with tons of different options.

The EV30 is designed to work with any pedal with an expression control option and the inputs into the EV30 feature a switch to change polarity depending on what brand of pedal you are using. For this review it seemed only right to use Boss products and the company sent us two pedals to use with the EV30, each of which had an expression input feature - a new Waza Craft Reverb (RV 6) which had a really cool shimmer reverb effect (as demonstrated in the video) so you can hear how this pedal can be used in real time - and a DM-2W, more of which anon. You can control the individual level parameters for each expression output, so you could for example have it affect your reverb a little bit more than your delay etc., so you can fine tune it that way as well.

As I say, the other pedal that I linked up to the EV30 was the new Boss DM-2W Delay pedal which has a rate input which can be controlled via the Expression pedal, thus controlling the speed of the delay pedal's rate switch.

Combining these two pedals in the demo, I was able to go from having a short slap back delay with a bit of spring reverb, all the way to a long delay and intense sounding spring reverb. It's a lot easier to demonstrate than describe, so please check out the video!

One of the great features of this particular expression pedal is its size. Some expression pedals can take up a huge footprint on the pedal board, and depending on what you are planning on using it for, you may not be able to justify all that space being taken up for a pedal you may only use a few times during a show. However, the EV30 has a small enough footprint to warrant it going onto most medium sized boards with lots of other pedals around it. It’s not so small however that you feel like your treading on egg shells when you lean on it and it has a nice smooth action, solid build and cool design to give you the confidence to use it on the fly at a show. The pedal doesn’t need to be powered to use it, which is an added bonus to making it fit on a small board without taking too much room and power.

My opinion on this pedal? Well it's great. It’s a quality, reasonably sized dual expression pedal, perfect for those who need to change sounds on the fly whilst performing. A whole myriad of uses could be found for this pedal and it doesn’t just appeal to guitarists only, because vocalists, bassists and keys players could also control their effect units via this great sturdy pedal. I also think it's very well priced for the quality and facilities on offer so well done, Boss!
