Last Friday, after coveting one for nearly 30 years, I finally bought an unlined fretless 4-string Steinberger XL2 from HeadlessUSA.
First, the obligatory photos:
It's been many years since I've handled an XL bass, and upon lifting it out of the case I was instantly struck by its density and heft. To anyone not familiar with the materials used in the construction of the Steinberger L/XL series, they might assume such a compact instrument would be featherweight, and dismiss it as an insubstantial novelty. Upon picking one up, however, I think that the weight, stiffness, and immediately apparent build quality are the first clues that this is no mere toy, and they hint to the XL's legendary status as a triumph of engineering and as a serious musical instrument.
Playing my first notes on the bass brought a huge smile to my face. It was instantly apparent that I've purchased a true, enduring classic. I've been playing the same bass since 1991, my Kubicki Factor fretless. During the past 28 years, I've tried other fretless basses, and I can count on one hand the number of instruments that I would actually have considered adopting. The two that come to mind are a fretless F Bass and a fretless Sukop bass. Both of them were wood construction, with traditional headstocks. I've tried out a few fretted Steinberger XLs over the years, but unfortunately I never had the opportunity to try a fretless. I did once see a narrow 5-string fretless XL in person, but it had already been sold and was not available to demo. My experiences with trying the fretted XLs made me appreciate their sonic clarity and sustain, and I always wondered how those qualities would translate to a fretless version. Alas, I shall wonder no more.
Unsurprisingly, the same qualities that make the fretted version of the XL bass so formidable are equally beneficial to a fretless. The stability and consistency of the composite unibody construction endows the XL bass with an incredible sustain and clarity that must be experienced to appreciate. The bass I purchased has a passive tone control. As I understand it, passive tone controls are cut-only; that is, the fully open position provides no boost of any frequency, and rolling back the knob gradually cuts higher frequencies. If that is the case, then what I'm hearing from the bass with no tone control cut is incredible. The combination of the XL's construction and its high-fidelity, full-range active EMG pickups results in a clear, brilliant tone that is rich in harmonics on top of the strong fundamental of each note. Any audio engineer will agree that subtractive EQ is always preferable to additive EQ. It's better to cut/filter frequencies than to artificially add them, because boosting frequencies also boosts the noise floor. In short - it's better to subtract what's there than to add what's not. In the case of the XL bass, it's there.
Moving on to playability: After having played the same bass for 28 years, an adjustment period to a new instrument is to be expected. Fortunately, the XL2UF is well within the range of my adaptability, and with some further tweaks, I expect to acclimate to it in short order. The bass's action, as received, was too a bit too high for my taste. It arrived well set up and balanced, but I did ultimately need to lower the action, and subsequently tweak intonation. Fortunately, the combination of double ball strings and quick, convenient Allen key and slotted driver bridge adjustment makes this process relatively painless. I'm still dialing in the fine tuning, but I'm 90% there.
There are some design differences between my Factor bass and the XL that will require some recalibration on my part. The XL's fingerboard, while not completely flat, has a flatter radius than my Factor neck, which has a more pronounced arch. The plastic covers of the EMG pickups are also flat across the top, unlike the Kubicki pickups, whose plastic covers replicate the same radius arch as the neck. This feels a bit different under my fingers, but it's not an insurmountable obstacle. The XL's EMG pickups also don’t extend as far out from either side of the strings as the Kubicki, so the place where I’m used to resting my right thumb is a bit closer to the string, as well as being less elevated from the body. Until I fully adapt to the XL's layout, it will feel a bit like I'm playing someone else's bass. Interestingly, I've used the same analogy when driving a new car. There is an initial break-in period in which one's muscle memory adapts to a new set of parameters.
For reasons I don't quite understand, the middle strings (A and D) register a few dB louder than the edge strings (E and G) with the same plucking force. There is not an appreciably large difference between the action height of each string, and the outer strings are actually
closer to the pickups than the inner strings, so I'm a little perplexed. I've raised the the action slightly on the A and D strings in an attempt to counteract the discrepancy in level, but there's still a slight difference. I'm curious to know if there's something specific to the EMG pickups' design that might favor the inner strings in this regard...
The "boomerang" is yet another impressive feat of engineering. I was quite surprised to find that once strapped on, the bass easily rotates around its pivot point, allowing changes in orientation without any strap adjustment being necessary.
I do have a couple of minor niggles. First, gloss black finishes are a fingerprint magnet! It's easy enough to keep a soft cloth in the case with the bass for post-session wipe-downs, but keeping the bass free of prints and smudges will require due diligence on my part. Second, glossy finish necks have a bit more thumb drag than satin finish necks. Rather than changing the finish of the bass neck itself, I think I might apply a satin vinyl appliqué strip to the back of the neck, which is an easily reversible, non-destructive modification. In any case, I'd prefer not to undertake any modifications that might diminish the bass's value as a collectible classic.
These are just my first impressions after having the bass for a few days. I'll be sure to add more observations once I've had time to play the XL for a while.
