ESP LTD MT-I Mick Thomson OBSM review

The ESP LTD MT-I Mick Thomson OBSM is a signature guitar built around a straightforward metal setup: a mahogany body, a white ash top, a through-body maple neck, and one bridge humbucker. Its listed price is 1,622, and it has been available since July 2025. The tested guitar made a strong impression both at ESP's Hellfest booth and during longer home use. The appeal is immediate for players who want a fast-playing instrument tuned for heavy riffs, though its very slim neck and single-pickup layout will not suit every guitarist.

Build, finish, and setup

The body uses mahogany beneath a white ash top, finished in Obsidian Metallic. The color reads as a grayish black, with green or beige tones appearing as the light changes. Black hardware completes the understated look. One owner described the finish and assembly as immaculate, and found the guitar well set up, with accurate intonation, a suitable neck bow, and low action. It arrived in its included case. A separate first-time owner reported that it was only slightly out of tune after shipping, with the low E string needing the most adjustment.

The three-piece maple neck runs through the body, and its Thin U profile feels notably slim. Players accustomed to thicker necks, including some Les Paul-style guitars, may need time to adjust. The neck finish was praised for its smooth feel. The Macassar ebony fingerboard has a 12-inch radius and 24 medium-jumbo stainless-steel frets. The 25.5-inch scale and 1.65-inch nut width are familiar dimensions for this kind of electric guitar. Access to the highest fret is especially good: the body shape lets the fretting hand reach the 24th fret without an awkward stretch.

Controls and pickup

Rather than offering a conventional set of pickups, the MT-I uses one Fishman Fluence Mick Thomson Signature humbucker at the bridge. A three-way toggle switch and a single volume control handle its available settings. The volume knob has a push-pull function for Voice 3. The controls can take a little time to understand, especially if you expect a typical pickup selector, but the layout becomes easier to use once each position is familiar.

In the standard voice, the pickup delivers a clear, forceful active sound. One player found it somewhat sterile on clean settings, but pulling up the volume control produced a much warmer clean tone with little apparent change in level. That added range is useful, though this guitar's strongest case remains overdriven playing.

Through a high-gain amplifier, the pickup was praised for tight low end, strong output, and substantial low mids. The reviewer preferred it to several familiar EMG sets and found it especially effective for low-tuned metal riffs. Voice 2 adds a bass shift, which may be excessive with an already bass-heavy amplifier. The pull-up setting also provides a single-coil-style option, adding a distinct tonal change without an obvious drop in volume. Voice 3, described by the owner as a passive voice, was less convincing in low tunings and high gain: that player heard little practical difference there.

Hardware and playing feel

The fixed Hipshot High Mass bridge keeps the design simple and stable, with no tremolo system. Open-gear Hipshot Grip-Lock locking tuners and a black TUSQ XL nut round out the hardware. The guitar ships with D'Addario YB-EXP110 strings and an included case. A battery is needed for the active pickup, but one buyer found no battery in the case and had to supply one separately. Check the package before a first session if you do not already have a suitable battery.

In use, the slim neck and generous upper-fret access make quick runs and wide stretches feel natural. The guitar's low action and firm bridge suit precise picking, while the pickup's tight response keeps low-tuned riffs controlled. It feels most at home in metal, but the warmer clean setting and alternate pickup voices give it useful options outside high gain. That versatility has limits: there is no neck pickup for rounder neck-position tones, and the third voice may not provide a noticeable change in every rig.

Verdict

The ESP LTD MT-I Mick Thomson OBSM is a carefully finished, fast-playing metal guitar with a distinctive signature humbucker and genuinely useful tonal changes. Its strongest points are its accessible 24th fret, tight low-end response, and responsive push-pull control. The very thin neck is a matter of preference, the single pickup narrows the traditional tonal palette, and Voice 3 may disappoint players seeking a clear passive alternative under heavy gain. For guitarists drawn to Mick Thomson's low-tuned riffing, it is a focused instrument that delivers a compelling playing experience. One buyer also noted that the retail price dropped by 200 shortly after purchase, so it is worth checking current pricing before ordering.
