The older S540 models are noted for their thin wizard necks, which are not matched by newer Prestige models unless it's a J Custom neck.

S540 models with full neck bindings and shark tooth inlays are considered more desirable.

Owners describe pre-1998 Japanese models as having thinner necks and being more precise compared to modern equivalents.

The S540 is preferred over other models like Sterling by Music Man and Epiphone SG due to its perfect body size, shape, and thin neck.

Some users on eBay and Reverb find Japanese listings unreliable due to duplicate photos and multiple listings for the same guitar.

One owner highlights that their 1994 S540 is their favorite guitar after owning a Sterling by Music Man, Epiphone SG, American Strat, and PRS SE.

One user noted a stress fracture around the nut on a used model, affecting playability.

Owners report that the S540FM's tuning stability is exceptional, outperforming other guitars with Floyd Rose systems even after heavy tremolo use.

The S540 addresses issues found in other guitars, such as neck heaviness in SGs and the thick, heavy feel of Fenders.

The S540FM is not traditionally suited for clean tones if fitted with high-gain pickups, but it's versatile enough for these tones with stock pickups.

The 'custom' inlay on the S540 was a standard feature, not a unique customization.

Some models feature aftermarket bridge pickups, which can impact tone and resale value.

These guitars can range from $500 to over $2000, depending on the year and features.

It's possible to find an S540FM under $1k on eBay, although availability and condition may vary.

The S540FM is described as part of a "holy trinity" of guitars by one owner, indicating a high personal value and preference.
