Frequently Asked Questions

Key factors include build quality, sound characteristics, playability, brand reputation, warranty coverage, and value for money. Consider your musical style, skill level, and intended use to find the best match.
Budget depends on your needs and experience level. Beginners can find quality options for $200-500, intermediate players should consider $500-1500 range, while professionals often invest $1500+ for premium features.
Higher-priced effect modules typically offer better materials, craftsmanship, and performance. They're worth it if you're serious about music, perform regularly, or need professional-grade features.
