The science of sound is an incredibly diverse topic. The range of frequencies we can hear is immense, so it's no wonder you'd want to find a way to balance it all out to sound as perfect or as imperfect as you desire. Equalizer and tone effects shaping pedals are the way to increase, decrease or equalize tones and frequencies of your electric guitar. With such a spectrum of options, one of these pedals is a great option to diversify your sound. Tone and EQ pedals both deal with customizing sounds but have separate purposes. The equalizer pedals deal with high, mid and low range frequencies on a variety of levels, while the tone shaping pedals help shift the actual tone of your electric guitar without having to alter your guitar's internal pickup. These incredibly useful tools allow you to customize, tweak and completely alter the output of your guitar. Equalizer pedals are also a great way to prevent feedback. If you plug in your guitar to the EQ pedal and set a frequency limit, your guitar will not register that sound. You save your ears and your gear from unnecessary damage. Tone shaping pedals, like the Rocktron Texas Recoiler, can actually help enhance the response of your guitar's internal pick up. The output, frequency and filter adjustments give you a range of options to play with so you can truly get the output you're looking for. As well, EQ and tone pedals can pretty much go anywhere on your pedal chain. Say your wah pedal is sounding a bit off to you. You simply plug in your pedal to the output, play with the tones and levels, and then plug your EQ pedal into the amp. You were just able to customize your pedal with a pedal. Keeping your custom sound in check is a major benefit of these types of pedals. It's not always feasible to change guitars when you're not happy with one or two elements. EQ and tone shaping pedals open the door for you to be able to correct sound and balance everything to your liking. Even if you want to throw your tone way off and create a specialty sound, equalizer and tone shaping pedals will do so effortlessly.
