10 Best Stereo Equalizers 2025 in the United States

The Boss EQ-200 Graphic Equalizer Pedal is a versatile and powerful tool for musicians and audio enthusiasts looking to shape their sound with precision. One of its main strengths lies in the 10-band graphic equalizer, which allows for detailed and specific adjustments across a wide range of frequencies. This makes it suitable for various styles, including bass and advanced usage, providing flexibility whether you’re playing live or recording in the studio.

The stereo input/output configuration is another significant advantage, enabling you to connect it easily with other stereo equipment for a rich, enveloping sound experience. Additionally, the inclusion of MIDI I/O expands its versatility, allowing for integration with other devices and more complex setups. The expression pedal/footswitch input further adds to its functionality, giving you hands-free control during performances. It also features a bypass function, which can be useful for quickly switching the equalizer on and off without interrupting the signal flow.

However, some potential drawbacks include the need for a power source, as it operates on 9 volts and comes with 3 AA batteries, which may not last long during extended use. Weighing in at 0.7 kilograms, it’s relatively light but still might add some bulk to your pedalboard. Despite these minor cons, it’s evident that users are generally very satisfied with its performance and reliability. Ideal for anyone from amateur musicians to professional audio engineers, the Boss EQ-200 stands out as a solid choice in the stereo-equalizer market.

With its dual 31-band constant Q frequency bands, it provides detailed adjustments for a wide range of sound frequencies, allowing users to fine-tune their audio output effectively. The switchable boost/cut ranges of 6 or 12 dB give flexibility for making significant changes or subtle tweaks in sound, which is a great feature for those seeking versatility in their setups.

One of the standout features is the front panel bypass switch, which allows for quick comparisons between the processed and unprocessed signals. This is particularly useful during live performances where setting adjustments need to be made rapidly.

While the 4-segment LED ladders for monitoring output levels are helpful, some users might find that they need more detailed visual feedback for fine-tuning. The weight of 7.9 pounds and dimensions can also make it less portable compared to smaller models, which might be a consideration for users who frequently move their equipment. The input and output connections via ¼” TRS and XLR are standard in the industry, ensuring good compatibility with most audio gear. Beginners might need to familiarize themselves with these connections if they are new to audio mixing.
