The Mustang Thinline is described as having a very middy tone, combining the typical Mustang sound with the midrange character of a semi-hollow.

It features standard Mustang wiring and single-coil pickups, maintaining classic Mustang sound characteristics.

The Mustang's pickup selector scheme allows for out-of-phase settings, ideal for alternative rock sounds.

The input jack is positioned at a right angle to the guitar face, unlike the bottom edge position on a Tele or slant on a Strat.

Owners note that the guitar's design, particularly the lack of body contouring, can make it uncomfortable to play for some users.

Despite its rarity, the Mustang Thinline has a niche appeal, with some owners selling theirs due to discomfort or dissatisfaction with its tone.

Owners find the short scale makes the Mustang easier to play, especially when seated or for players with smaller hands.

Installing a Mastery bridge significantly enhances sustain, expanding the tonal possibilities and making it more versatile.

It's noted that the short scale impacts the tone significantly, making the guitar less versatile compared to alternatives like custom BiLT models.

Compared to the Squier Super-Sonic, the Mustang Thinline uses single-coil pickups, offering a different tonal palette than the dual humbuckers in the Super-Sonic.

Mustangs are lighter, comparable to thinline Teles, and feature a mellower neck pickup tone than Strats, making them suitable for jazz.

The Mustang Thinline features a single-bound design with soft edges, contrasting with the more polarizing double-bound designs that some find uncomfortable.

The Mustang Thinline is produced in the Japanese Fender plant, known for high-quality craftsmanship.

Despite being a short-scale offset, some owners find it so unique and visually appealing that they choose to keep it over other guitars.

The bridge/tremolo system lacks individual string height adjustments, a common complaint among owners.
