    Source
  • The Bassballs Nano is known for being compact, but some users find that it doesn't offer any tonal advantage over the regular Bassballs despite its smaller footprint.

    Source

    Source

Mods and upgrades

  • Internal trimpots allow customization, transforming the pedal into a bubbling distortion sensitive to picking dynamics, offering a unique sound adjustment for different setups.

    Source
  • The internal trim pots can be relocated externally for easier access, though many find the default settings optimal, indicating limited practical need for frequent adjustments.

    Source

Use cases and applications

  • Works best on slower, open riffs and can add a spacey, wah-like growl when paired with distortion pedals, making it ideal for atmospheric and psychedelic music.

    Source
  • Adding a compressor before the Bassballs can enhance the sound, providing thicker and more dynamic envelope effects.

    Source
  • Some users report that the EHX Bassballs' distortion can significantly reduce low end, making it less suitable for bass-heavy music styles.

Comparisons

    Source

    Source

User experience

    Source
  • Users mention that the Bassballs pedal is a "one-trick pony," effective for its unique sound but limited in versatility, leading to infrequent use.

    Source
  • Some users find the filter effect weak, barely noticeable even with sensitivity maximized, suggesting varied satisfaction with its performance.

    Source

Build quality

  • A potential grounding issue can cause the pedal to become microphonic, allowing physical knocks to be heard through the amp.

    Source

Setup and maintenance

  • The manual indicates no output at zero sensitivity with distortion enabled, confirming a design characteristic rather than a defect.

Critic Reviews

Electro-Harmonix Bassballs review | MusicRadar

musicradar.com

Electro-Harmonix Bassballs delivers a funky, phased wah-like effect that’s a fun addition to any bassist’s toolkit, especially for those dabbling in funk. Its simplicity shines with only one adjustable control, making it a breeze to dial in. However, its niche appeal means it might not become a staple for every player. While it doesn’t redefine your soundscape, it’s a nifty tool for adding flair to specific tracks or phrases.
