For guitarists seeking the deep, heavy tones of an 8-string guitar without switching instruments, various methods exist. While hardware solutions involving heavy gauge strings, down-tuning, and octave pedals can offer a semblance of the extended range, they often fall short of truly replicating the authentic 8-string sound. Achieving a convincing 8-string guitar tone is more effectively realized through software, specifically with advanced amp simulation plugins that feature pitch-shifting or transposing capabilities.
Leading the way in this domain are companies like Neural DSP and Mixwave, who have integrated sophisticated transpose features into their amp simulations. Neural DSP offers this technology in several of their popular amp sims, including Rabea, Plini X, Petrucci, and Gojira X, with ongoing updates potentially bringing this feature to more of their product line beyond the Nolly plugin. Mixwave’s Spiritbox amp sim stands out as another excellent option, rivaling Neural DSP in the quality of its pitch-shifting implementation. For guitarists aiming to authentically emulate an 8-string guitar using a standard six-string, these amp sims represent the most practical and sonically superior route.
Choosing between Neural DSP and Mixwave ultimately depends on individual preferences and musical styles. For those targeting the ultra-heavy, doom-laden metal genres typically associated with 8-string guitars, Neural DSP’s Gojira X and Mixwave’s Spiritbox are particularly well-suited. The Gojira X is renowned for its aggressive high-gain tones, ideal for modern metal, while the Spiritbox excels in capturing a crushing, dense sound that mirrors the impact of an 8-string. Although Neural DSP has established a stronger market presence, Mixwave should not be overlooked as their amp sims offer comparable quality and innovation.
A significant advantage of exploring amp sims from both Neural DSP and Mixwave is the availability of free trial periods. These trials allow guitarists to personally evaluate the plugins, experiment with their features, and determine which best aligns with their sonic goals and workflow before making a purchase. This hands-on experience is invaluable in selecting the right tool to bridge the gap between a six-string guitar and the expansive soundscape of an 8-string instrument.
