Reverb & Delay Pedals
The delay pedal is often neglected, but indeed it is an effect pedal you should never be without. Especially if you're a huge Pink Floyd or Queen fan and you want to sound just like the original. The reverb pedal will make your guitar sound as if you are playing in a big room, adding "air" and "space" to your music. If you are looking for a more lively and deep sound, then you probably need to add a reverb pedal to your setup. But if you need an effect that will repeat the notes to make your guitar sound a lot fuller, then deffinitely look for a delay pedal.
