For acoustic guitarists exploring the world of multi-effects processors, the Line 6 Helix often surfaces as a compelling option. One of its standout features, particularly beneficial for acoustic instruments, is the inclusion of a dedicated high impedance “Aux” input. This feature alone can significantly influence an acoustic player’s decision, setting it apart from units like the HX Effects, which lacks this specific input. While some users find success utilizing the standard “Guitar” input or the return inputs on the Helix for their acoustic guitars, the “Aux” input presents a distinct advantage depending on your acoustic guitar’s pickup system and preamp. The tonal characteristics of the “Aux” input might be more favorable for certain acoustic setups compared to the standard “Guitar” input, though experiences can vary, and the regular “Guitar” input or even a return input on the HX Effects could suffice for many.
It’s worth noting that the amp and cabinet simulations or impulse responses (IRs) within the Helix ecosystem are not typically the primary draw for acoustic guitarists. While Helix does offer IR loading capabilities, and the HX Effects shares this feature, achieving excellent acoustic tones often doesn’t necessitate these functionalities. Many players find they can dial in superb acoustic sounds on the Helix without relying heavily on amp/cab modeling or IRs. However, the addition of dedicated acoustic amplifier and cabinet models to the Helix platform would undoubtedly be a welcome enhancement for acoustic players seeking to further refine their sound.
Beyond input options and amp modeling, the Helix boasts a broader feature set that appeals to musicians who play both acoustic and electric guitars. These advantages include expanded input/output options, such as XLR outputs not found on the HX Effects, additional effects loops for complex routing, the convenience of integrating a microphone for vocal processing, dual guitar inputs including the aforementioned “Aux” input, and a built-in expression pedal for real-time parameter control. Furthermore, Helix owners benefit from a substantial discount on the Helix Native plugin, a software version of the processor, offering seamless integration between studio and stage.
However, it’s crucial to acknowledge that the absence of these advanced features in the HX Effects doesn’t automatically disqualify it as a viable option for acoustic guitar. The HX Effects presents its own set of compelling advantages, primarily its more affordable price point and a significantly smaller footprint, making it ideal for pedalboards where space is at a premium. Ultimately, the decision between the Helix and HX Effects for acoustic guitar hinges on a player’s specific needs and priorities. If the comprehensive feature set of the Helix, including the “Aux” input and expanded I/O, aligns with your playing style and requirements, the additional investment, larger size, and increased weight may be justified. Conversely, if cost and pedalboard real estate are primary concerns, and the advanced features of the Helix are deemed less critical, the HX Effects could serve as a highly capable and more economical solution for processing acoustic guitar signals. Carefully evaluating your individual needs and how you intend to utilize these features will guide you to the optimal choice between these powerful Line 6 processors.
