Key Info

Boss EQ-200 Graphic Equalizer Pedal features Dual 10-band EQs that can be used in stereo, in parallel, or in series

Precise tone-shaping

When it comes to shaping the frequency content of your signal, amplifiers can be a little bit limited. That's where the Boss EQ-200 comes in. With two 10-band EQs in one compact box, you can take complete control of every aspect of your sound with incredible accuracy. Each band can be cut or boosted by up to 15dB, whilst a handy overall Level slider means you can easily balance the volume with your bypassed signal, or kick things up a notch with a boost for solos and lead lines. And with the ability to change the frequency range and frequency centres with three selectable options (30Hz to 12.8kHz, 32Hz to 16kHz, and 28Hz to 14kHz), you can optimise your pedal to suit a huge variety of instruments.

Phenomenal flexibility

The frequencies aren't the only flexible aspect of the EQ-200. With a variable signal flow structure, you can operate your pedal in one of three different modes to suit your needs. On the rear panel, there are two inputs - A and B. These can be linked together or used on their own, giving you options for Stereo equalisation, as well as being able to switch to Parallel or Series modes. When in Series mode, the two EQs are run one after the other, letting you shape two separate tones for a variety of different situations, whilst Stereo and Parallel offer that extra touch of versatility for a range of rigs and setups.

Intuitive real-time control

Equalisation can be intimidating. That's why the EQ-200 has been designed to make sculpting your tone both easy and enjoyable. The control panel gives you hands-on controls with a satisfying tactile response, making your workflow fast and hassle-free. Adjusting each frequency band is smooth with an exceptional tonal response, whilst a dedicated panel button lets you toggle between channels with ease. And when you want to stop any unwanted or accidental changes, you can simply use the integrated Panel Lock function, keeping your settings exactly as they are.

The EQ-200's intuitive nature goes beyond the look and feel of the pedal. Intelligent features such as the four onboard memories make setting up your board incredibly easy. Each memory can be saved by simply holding the memory button, whilst a Manual setting lets you quickly jump to the settings that are currently set on the panel itself.

The pedal's controls are expandable too. The default footswitches allow you to toggle the pedal on and off, as well as scroll through your memory slots. However, these can be reassigned to switch specific channels on or off, to select specific memories, and much more. The EQ-200 also provides you with the ability to control your pedal using external footswitches, which can also be assigned in any way you wish. There's also a rear panel connector for hooking up an expression pedal, giving you intuitive level control for either channel, or the overall output level. Plus, with MIDI I/O via mini TRS jacks, you can operate a plethora of functions from external MIDI controllers, as well as chaining multiple 200-Series pedals for quick and easy simultaneous memory selection.

Uninterrupted sound quality

When you've got so many different features, functions, and voices to play with, it can be easy to forget that above everything, a pedal has to sound good. Boss certainly haven't forgotten this. The EQ-200 features 32-bit AD/DA, 32-bit floating point processing, and a 96kHz sampling rate - all coming together to provide premium sound quality and clarity. This is a pedal that'll only ever make your signal better, never worse.
