The short version

Two things separate this from the rest of the Core series. The first is the 44.5 mm nut — a quarter of an inch wider than the others, which is the width fingerstyle players ask for because it gives each string room and stops the thumb muting the sixth. The second is blackwood, an Australian acacia closely related to koa, which sits in an unusual place tonally: the rich low end of mahogany, something of the brightness of maple, and the complex overtones people buy rosewood for. The Grand Auditorium body is the balanced middle size, less boomy than a dreadnought and louder than a concert, and Elixir coated strings come fitted from the factory.

The good and the bad

What we like

44.5 mm nut gives fingerstyle players the string spacing they actually need
All-solid blackwood is a rare and tonally distinctive timber at this price
Grand Auditorium body is balanced and easy to record
Bone nut and saddle plus Elixir coated strings fitted from the factory

What we do not

The wide nut works against players with small hands or a barre-chord style
Blackwood is unfamiliar enough that resale is harder to predict
Almost no published owner reviews so far

What owners and reviewers report

Patterns we found across published reviews and owner feedback. These are summaries of recurring themes — we do not reproduce or invent individual testimonials.

What comes up most

Too few published owner reviews to establish a reliable pattern

Frequent complaints

Too few published owner reviews to establish a reliable pattern

Recognised strengths

All-solid blackwood construction with bone hardware is a specification well above the usual for this bracket

Recognised weaknesses

Owner feedback volume is too low to judge unit-to-unit consistency

The verdict

If you play with your fingers rather than a pick, this is the one in the range to look at, and the wide nut is the reason. Blackwood is genuinely distinctive — more complex than mahogany without the scooped midrange that makes some rosewood guitars hard to mix — and an all-solid body in that timber at this price is rare. The Grand Auditorium shape also records more easily than a dreadnought because there is less low-end to fight. Against it: the wide nut is a disadvantage if you have small hands or play mostly barre chords, and there is almost no published owner feedback yet.

Strings for this guitar

All strings

It ships with Elixir Phosphor Bronze Nanoweb Light (.012-.053). Staying at that gauge keeps the setup and the neck relief as the factory left them; going a step lighter makes bending easier, a step heavier gives more volume and tension. Anything more than one step either way usually needs the truss rod and the intonation adjusted.
