When choosing an octave pedal, there are several factors to consider:

1. Sound quality: This is the most important factor to consider when choosing an octave pedal. You want to choose a pedal that produces a high-quality octave sound that fits well with your playing style.

2. Tracking: The tracking refers to how well the pedal detects the pitch of the note being played and generates the corresponding octave. Look for a pedal with fast and accurate tracking, as this will help you create smoother and more natural-sounding octave effects.

3. Controls: Octave pedals typically have controls for adjusting the amount of octave effect and the mix of the original and generated signals. Look for a pedal with intuitive and responsive controls that allow you to fine-tune the effect to your liking.

4. Additional features: Some octave pedals have additional features, such as the ability to add distortion or other effects to the generated octave. Consider whether these features are important to you and whether they will add value to your playing.

5. Price: Octave pedals are available at a range of prices, from budget options to high-end models. Consider your budget and choose a pedal that offers the features and sound quality you need at a price point that works for you.

Ultimately, the best way to choose an octave pedal is to listen to the demo videos we have for the various models we carry and see which one sounds and feels best for your playing style.
