Owners find the Suhr pickups in the Prog NX6 superior, offering a wider tonal range compared to the Classic NX's stock pickups.

The Salen Jazz has been compared unfavorably to a PRS 24 and MiJ Telecaster 52 for lacking a "buttery, smooth, mellow" acoustic feel.

A user compared the fretwork of the Strandberg unfavorably to an Eastman jazz guitar at a similar price, highlighting quality control concerns.

Some owners recommend using LaBella flatwounds to avoid issues with strings unwinding in the locking system.

Owners suggest experimenting with flatwound or half-round strings to mellow tone, but caution against the necessity to re-cut the nut due to the zero fret design.

Replacing the input jack with a four-point contact jack is recommended to improve reliability.

The Salen Jazz is noted for its ergonomic benefits, particularly for users with wrist issues, despite some tonal dissatisfaction.

Users report a "direct" tonal characteristic, noting it lacks the "pillowy" or "smooth" feel found in other semi-hollow guitars like the 335.

The Sälen's strap button location on the top horn is preferred for comfort in seated positions compared to the Boden's back-of-horn placement.

Some owners experience a knocking sound when moving the tremolo bar quickly, possibly due to unbalanced pivot screws.

The guitar's zero fret design means the nut primarily acts as a string guide, not affecting string height at the zero fret.

The Prog NX6 features Suhr SSH+/SSV pickups, praised for brighter lead tones, while the Sälen's pickups might lack the thickness found in DGT humbuckers.

The Prog NX6 is chambered, offering more resonance, while the Sälen Classic is solid body, potentially reducing sympathetic string noise with lighter gauge strings.

The neck's ridge design aids in optimal hand positioning and reduces friction, enhancing speed and cleanliness in play.

Using Ernie Ball Beefy Slinky 11-54 in Drop C tuning is comparable in tension to 9-42 or 10-46 in standard tuning, affecting string noise.

Slight adjustments like tightening tremolo bar nuts and polishing the neck with 0000 gauge steel wool can resolve minor build quality issues.

Owners report the input jacks, supposedly Switchcraft, may have weak solder joints and loosen over time, suggesting potential quality control issues.
