Common Les Paul Junior Mistakes to Avoid

The Les Paul Junior is the kind of guitar that sounds so good so quickly that people sometimes skip the care and thought that would make it even better. The mistakes that come up repeatedly aren't complicated — they're mostly about not adjusting your expectations correctly, not bothering with a proper setup, and trusting a key-count label on a case. Here's what to watch out for.

Mistake 1: Not Getting a Proper Setup

This applies to almost any guitar, but it's especially true here because a well-set-up Junior and a poorly set-up one feel like genuinely different instruments. The wraparound bridge doesn't self-calibrate. The neck doesn't arrive from the factory in perfect relief. The nut slots may need attention. A tech who does a thorough setup — action, relief, nut, pickup height — typically charges £40–70 and produces results that would take most players months of frustration to discover on their own.

If the guitar buzzes excessively, goes out of tune on the third fret, or sounds oddly thin, the setup is the first thing to fix — not the guitar itself.

Mistake 2: Assuming More Gain Solves Tonal Problems

This guitar's bridge P-90 is designed to work with a responsive amp and judicious use of the volume control — not with the gain cranked to maximum through every pedal on your board. Piling on gain doesn't improve the sound; it flattens the dynamics that make the P-90 interesting in the first place and produces a harsh, noisy result. Try: amp set to a moderate breakup, guitar volume at 7 or 8, and pick with intention. The character comes from the interaction, not the distortion level.

Mistake 3: Dismissing It as a Beginner Guitar

The "Junior" in the name refers to the original pricing tier, not the instrument's capability. This guitar has been used on professional recordings and stages for over 70 years. Players who dismiss it as a beginner's option or a step below a "real" Les Paul miss the point: the Junior's stripped-back design is a deliberate tonal choice, not a compromise. The single P-90 and simple controls produce a directness that a two-humbucker guitar simply doesn't have. That directness is the reason professionals reach for it.

Mistake 4: Buying the Wrong Size Case

Single-cutaway and double-cutaway Juniors have different body shapes, and a case that fits one may not fit the other. Neither version shares exact dimensions with a standard Les Paul Standard or Custom, so cases labelled "Les Paul" may not fit correctly without checking the internal dimensions. Measure your specific guitar and verify the interior dimensions of the case before you buy.

Mistake 5: Overlooking the Volume Control

One of the specific pleasures of playing through a good tube amp is the range of tones available from the volume knob alone. Most players turn it to 10, leave it there, and then wonder why the tone feels one-dimensional. Try this: set the amp to medium breakup, then compare 10, 8, 6 and 4 on the guitar. Each setting produces a meaningfully different sound — brighter and more aggressive at full, cleaner and rounder as it comes down. The guitar rewards this kind of active control in a way that a channel-switching amp obscures.

Mistake 6: Buying Cheap Copies With Incorrect Pickups

The budget end of the clone market is full of instruments with pickups that look like P-90s but aren't wound or voiced like them. The recognisable character of this design — the midrange push, the natural overdrive, the interaction with the volume control — depends on the pickup behaving as a P-90 should. An incorrectly voiced imitation produces a thinner, less responsive result that makes the whole guitar feel like a compromise. If you want the sound, buy from a maker who uses a genuine P-90 or a well-regarded P-90 variant.
