120 Boss effects in a pedal narrower than two standard Boss pedals side by side.

Run up to four effects at once and control everything with two footswitches.
- Gear Suite gives you ready-made sounds for every effect with one turn of a knob
- Effects loop, so your own pedals can sit anywhere in the chain
- Stereo in and out plus TRS MIDI for the rest of your setup

Room for what your board is missing
Most pedalboards are built with care, and there is rarely room for more. The EX-4 is 11.7 cm wide and weighs 800 grams, yet it holds 120 effects from the Boss catalogue. It suits players who want to keep their core pedals and have everything else in one place. Guitar World gave it 4.5 out of 5 and called it "a capable little device that offers a huge amount of versatility".
120 effects, four at a time
All the major categories are covered: overdrive and distortion, modulation, delay and reverb. There are also bass-tuned effects and Boss classics such as Slow Gear and Slicer. You can run up to four effects at once, including several of the same type, and combine them in series, in parallel or with separate wet/dry. Guitar World singled out the compressor, Slow Gear, the modulation effects and the delays, with the rotary as its favourite.
On top of the four effects you get foot volume, two noise suppressors, send/return and a divider/mixer, which can be placed anywhere in the chain. A global EQ shapes the overall sound at the end.
Gear Suite: ready-made sounds with one turn
Each effect type has several ready-made Gear Suite settings tuned by Boss. Turn a knob and you have a usable sound straight away. If you want to go further, adjust the parameters and save your own versions. There are 128 preset sounds for guitar and bass and 128 slots for your own.
Clear overview on stage
The 2.4-inch colour display shows the whole effect chain. Each effect has its own FX button: a short press turns it on or off, and a long press opens its settings. The button colours match the colours on the screen. The two footswitches have coloured LEDs around them, so you can see what they do right now. You decide whether they switch effects, change sounds, tap tempo or act as master bypass, and this can be set differently for each sound.
Connections
Four jacks give you mono or stereo. In mono, two of them can be used as an effects loop, so an external pedal can sit anywhere in the EX-4's chain. You can add two extra footswitches or an expression pedal, and TRS MIDI in and out connects it to other MIDI pedals, switching systems and clock. With certain configurations, delay and reverb ring out when you change sounds.

Questions and answers
Can I use it with my own pedals?
Yes, that is what it is built for. Put it on your board next to your core pedals, and use the effects loop if one of them needs to sit in the middle of the EX-4's chain, for example your overdrive between a compressor and a delay.
Can I use it with bass?
Yes. Some of the 120 effects are tuned for bass, and the 128 preset sounds include sounds for bass.
Can I play in stereo?
Yes. There are two inputs and two outputs, so you can run stereo all the way through the pedal. The effects loop uses the same jacks, so it is only available when you play in mono.
Are two footswitches enough?
For most songs, yes. You decide what each switch does, and it can differ from sound to sound. If you need more, you can add a dual footswitch such as the Boss FS-6 or FS-7, or control it via MIDI.
Is a power supply included?
Yes. It comes with a Boss adapter (PSA-S series), a startup guide and four rubber feet for use off a pedalboard.
