IYV IMM-350 5-String Electric Bass Review: A Precision-Engineered Powerhouse for the Modern Bassist

As bassists, we’ve all been there: standing in a music shop, staring at a wall of instruments, wondering if we truly need to spend a month’s rent to get a 5-string that doesn’t feel like a piece of lumber. The struggle is real. Many affordable 5-string basses suffer from the “floppy B-string” syndrome or necks that warp under the added tension of that heavy fifth string. For the gigging musician or the home recorder, finding an instrument that offers stability, tonal clarity, and aesthetic appeal without a premium price tag feels like hunting for a unicorn. This is exactly why the IYV IMM-350 5-String Electric Bass caught our eye. Solving the problem of high-entry costs for professional-spec instruments is crucial; otherwise, budding musicians are stuck with gear that hinders their growth rather than inspiring it. We decided to put this CNC-machined wonder to the test to see if it truly lives up to the hype.

Choosing Your Foundation: What to Look for in a Solid Body Electric Bass

A Solid Body Electric Guitars is more than just an item; it’s a key solution for musicians who need sustain, feedback resistance, and a platform for diverse tonal shaping. Unlike hollow bodies, a solid body bass like the IYV IMM-350 5-String Electric Bass provides a focused, punchy sound that is essential for cutting through a dense mix in genres ranging from gospel and jazz to heavy metal and funk. The density of the wood and the integrity of the construction determine how well those low frequencies translate from the string to the amplifier.

The ideal customer for this type of product is someone facing the limitations of a 4-string bass—specifically the need for those lower notes (D, C, and B) without detuning—while it might not be suitable for those who prefer the lightweight, acoustic resonance of a semi-hollow instrument or beginners with very small hands who might find the wider 5-string neck intimidating. If you are looking for a smaller scale, you might consider a short-scale 4-string, but for the modern player, the 5-string is becoming the standard.

Before investing, consider these crucial points in detail:

• Dimensions & Space: When moving to a 5-string, neck width and string spacing are paramount. You want a neck that feels substantial enough to handle the tension but slim enough for fast runs. The IYV IMM-350 5-String Electric Bass utilizes a full-size scale, so ensure your gig bag and studio space can accommodate its length.
• Capacity/Performance: In the world of bass, “capacity” refers to tonal range and tuning stability. A high-performance bass must maintain a “tight” low B string. If the string feels like a wet noodle, the performance suffers. Precision CNC construction is a major factor here, as it ensures the bridge and nut are perfectly aligned.
• Materials & Durability: Look for tonewoods that balance weight and sound. Ash is known for its “scooped” sound with bright highs and firm lows, while Basswood is prized for its lightweight nature and flat, even frequency response. The combination of these in one instrument can offer a very balanced sonic profile.
• Ease of Use & Maintenance: A good bass should be “plug and play” but also easy to adjust. This includes having a reliable truss rod for neck adjustments and accessible electronics. We always look for instruments that don’t require a professional luthier just to change the action or intonation.

Understanding these factors allows you to see why certain brands are pivoting toward high-tech manufacturing to deliver better value. While the IYV IMM-350 5-String Electric Bass is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

First Impressions: Unboxing the IYV IMM-350 5-String Electric Bass

When we first pulled the IYV IMM-350 5-String Electric Bass out of its packaging, the natural finish immediately grabbed our attention. The grain of the Ash wood top is striking, giving it the look of a boutique instrument that usually costs three times as much. It’s a full-size beast, but the ergonomic tapering and shape make it surprisingly comfortable against the body. One of the first things we do is check the “feel” of the neck. Thanks to the CNC (Computer Numerical Control) machining, the fretwork felt remarkably consistent for a factory-direct instrument. You can see its full feature set and user reviews to get a sense of how others felt upon first contact, but our initial take was that IYV is punching way above its weight class in terms of aesthetics and initial build quality.

Deep Dive: Analyzing the Performance of the IYV IMM-350 5-String Electric Bass

Precision Engineering: The CNC Manufacturing Difference

The standout claim for the IYV IMM-350 5-String Electric Bass is its CNC machine construction. In our testing, this isn’t just a marketing buzzword. CNC machining allows for 3D computer programming to dictate the exact cuts of the wood. When we ran our hands down the neck, the tapering was flawless. We’ve played many budget basses where the neck feels “thick” in the wrong places, leading to hand fatigue during long sets. The IMM-350 avoids this entirely. The “strong fingerboard without bending” mentioned in the specs held true even when we swapped the factory strings for a heavier gauge. This level of precision ensures that the neck pocket is tight, which is the secret sauce for sustain. When the neck and body are joined with such accuracy, the entire instrument vibrates as one unit, a feature that really sets it apart from other mass-produced models in this price bracket.

Tonal Palette: Ash, Basswood, and Nickel Strings

The marriage of an Ash wood top with a Basswood back is an interesting choice that we found provides a very versatile sound. During our studio sessions, we noticed the Ash top provides that characteristic “snap” and “pop” that slap bassists crave. However, the Basswood back rounds out the mid-range, preventing the bass from sounding too thin or brittle. This makes the IYV IMM-350 5-String Electric Bass a chameleon in the studio. Whether we were playing through a clean DI or a grittier tube amp, the nickel strings provided a smooth, warm response that sat perfectly in the mix. To truly appreciate the sonic depth, you should check the latest price and availability and consider how this tonewood combination fits your specific genre. We found it particularly effective for modern R&B and Rock, where you need both a solid foundation and the ability to cut through with clear high-end definition.

Playability and the 5th String Challenge

The true test of any 5-string is the B-string. We’ve all played basses where the lowest string feels disconnected from the rest of the instrument—muffly, quiet, or just plain loose. On the IYV IMM-350 5-String Electric Bass, the string tension is remarkably balanced. This is likely due to the combination of the CNC-carved nut and the bridge placement. We were able to achieve a low action without excessive fret buzz, which is a testament to the level fingerboard. Playing fast arpeggios across all five strings felt natural. For those looking at investing in a professional-grade instrument for the first time, the playability here lowers the learning curve significantly. We didn’t feel like we were “fighting” the instrument to get a clean note out of the low B, which is a common complaint with many entry-level 5-string models.

Aesthetics vs. Reality: The Finish and Hardware

While the CNC work is top-tier, we have to talk about the finishing. As we spent more time with the IYV IMM-350 5-String Electric Bass, we looked closer at the hardware. The knobs are functional and have a decent weight to them, but as some users have pointed out, the finish application in the recessed areas (like under the knobs) can be a bit rough. In our evaluation, we noticed that while the top face of the guitar is gorgeous, the attention to detail in the hidden nooks isn’t quite at the level of a $2,000 custom shop bass. However, this is a minor cosmetic gripe when you consider the structural integrity of the instrument. We recommend exploring the full technical specifications to see the hardware details for yourself. For most players, the trade-off of a slightly imperfect finish under a knob for a rock-solid, CNC-machined neck is a deal they would make any day of the week.

What Other Users Are Saying

The general sentiment among owners of the IYV IMM-350 5-String Electric Bass is one of pleasant surprise, though it isn’t without its critics. Many users praise the instrument for its “unbelievable value,” noting that the neck stability is far superior to other brands at this price point. One bassist mentioned, “The CNC precision is evident; I didn’t have to do a full setup out of the box, which is unheard of.”

However, we must address the balanced view. As one user noted, “The instrument has no finish under the guitar knobs… the knobs grind against the wall of finish they are surrounded by. It looks like they are sunk into the guitar finish.” This confirms our own findings that while the “bones” of the guitar are excellent, the final “beauty pass” in the factory can sometimes be rushed. Another user echoed this, stating that while the sound is “pro-level,” they had to spend a little time smoothing out the control cavities. Despite these minor cosmetic issues, the overwhelming consensus is that for the money, you are getting an instrument that plays and sounds like it belongs on a much larger stage.

Expanding Your Horizons: How It Compares to Other Solid Body Favorites

While we are impressed with the IYV IMM-350 5-String Electric Bass, it’s important to look at how it compares to other options in the solid body category. Depending on your age, skill level, and musical goals, one of these alternatives might suit you better.

1. Squier Mini Strat Electric Guitar Bundle

If you are looking for an instrument for a younger player or need something for travel, the Squier Mini Strat is a completely different animal. While the IYV is a full-scale 5-string bass meant for deep low-end, this 3/4-size guitar is designed for comfort and small hands. It’s a great “first guitar,” but it lacks the professional CNC construction and the extended range of the IYV IMM-350 5-String Electric Bass. You would choose this if you are focused on learning six-string chords rather than laying down a bass groove. It’s a fantastic value bundle, but it serves a much different purpose in the musician’s arsenal.

2. WestCreek Revenge Electric Guitar Heavy Metal

The WestCreek Revenge is aimed squarely at the metal guitarist. Featuring high-output pickups and a mahogany body, it’s built for distortion and shredding. When compared to the IYV IMM-350 5-String Electric Bass, the WestCreek offers a more aggressive aesthetic and rounded end jumbo frets which are great for lead playing. However, for those who need a rhythm foundation, the IYV’s 5-string bass configuration is irreplaceable. If you’re a guitarist looking for a heavy metal axe, WestCreek is a solid contender, but it doesn’t offer the multi-tonal versatility that the IYV bass brings to a full band setting.

3. Ibanez GIO GRX70QA Electric Guitar

The Ibanez GIO series is legendary for providing “bang for your buck.” This model features a quilted maple art grain top that rivals the IYV’s Ash top in beauty. The GIO is a versatile 6-string guitar with a tremolo bridge, making it better for players who want to experiment with whammy bars and diverse pickup switching. However, the IYV IMM-350 5-String Electric Bass feels a bit more robust in its neck construction. While the Ibanez GIO is a fantastic entry-to-mid-level guitar, the IYV IMM-350 feels more like a specialized tool for the serious bassist who needs that low B string to be crystal clear.

Final Verdict: Is the IYV IMM-350 5-String Electric Bass Your Next Workhorse?

After putting the IYV IMM-350 5-String Electric Bass through its paces, our conclusion is clear: this is a phenomenal instrument for the price. The use of CNC technology has effectively eliminated the most common issues found in budget 5-strings, namely neck instability and poor fret alignment. While there are some minor finishing flaws—specifically around the control knobs—these are purely cosmetic and do not detract from the instrument’s playability or tone. The combination of Ash and Basswood creates a balanced, punchy sound that can handle everything from smooth jazz to aggressive metal.

We recommend this bass to any intermediate player looking to step into the world of 5-strings, or even professional players who need a reliable, high-quality backup that they don’t have to baby. It’s an inspiring tool that solves the problem of finding a “tight” low B without spending thousands. If you’re ready to upgrade your sound and explore the depths of the 5-string range, we suggest getting your hands on this versatile bass today and seeing just how much value IYV has packed into this natural beauty.
