Overview: “Big three” non-solid guitar constructions

The video explains how full hollow-body, semi-hollow, and chambered guitar designs affect acoustic resonance, pickup mounting, tone, and especially feedback resistance. It notes these construction styles trace roots to the 1950s (and earlier for acoustic/archtop concepts), and that manufacturers sometimes use inconsistent labeling.

1) Full Hollow-Body Guitars

Key construction traits

  • Built similarly to acoustic/archtop guitars, but with f-holes instead of a single soundhole (often compared to violin/archtop heritage).
  • Historically, before modern amplification, these were intended for natural projection because there were no pickups.
  • Typical hardware approach mentioned:
    • Bridge not screwed down (described as “floating”)
    • Tailpiece floating, mounted into an internal support block
  • Later electrified versions address pickup mounting by using:
    • A floating pickup attached to the pickguard
    • Controls/wiring designed to avoid interfering with the player

Performance / tonal implications

  • Main benefit: you can play it more like an acoustic (unplugged) and also mic/amp it for added resonance.
  • It can help you “mix” more acoustic-like sound with amplified electric tone.

Main downside

  • Feedback is the classic issue with full hollow designs.

Examples cited

  • Gibson L-5, CES, Super 400
  • D’Angelico and another similarly-styled maker (referenced as D’… / D’Aprás?)
  • Mentions Gibson in a 30s jazz arch top context

2) Semi-Hollow Guitars

Core idea

  • Semi-hollow designs aim to tame/eliminate feedback compared with fully hollow bodies by adding structure under the pickups/bridge.

2A) Thin body + center block (most famous approach)

Key construction traits

  • Example: Gibson ES-335 / ES models
  • Uses a much thinner body plus a solid maple center block to support pickup and bridge mounting.
  • Laminate top/back/rims to balance durability and resonance.

Tone / use-case

  • Less feedback at higher volumes, making them strong for blues and rock.

Materials / quality note

  • The video advises checking laminate construction quality on lower-cost models, because layer separation can occur over time.
  • Mentions Gibson builds using three plies of maple and poplar.

Examples cited

  • Gibson ES-335
  • Gretch/Electromatic-style models and Epiphone Sheraton II / Sheraton 2 (center-block semi-hollow approach)
  • Mentions Gretch 5655 as part of an affordable Electromatic line (spelling may be off)

2B) “Chambered-leaning” variants (routing out inner wood)

Key construction traits

  • Mentions Rickenbacker 330 / 360:
    • A maple slab is routed to remove interior mass
    • Older models described as using X bracing
    • Newer ones route bracing into the body

2C) One f-hole “semi-hollow” style

Example cited

  • Reverend Club King 290

Construction traits

  • Uses a single slab of carina (back + sides)
  • Capped with a solid spruce piece (not laminate)
  • Only one f-hole, creating more internal bracing around pickups/bridge than typical full hollow layouts

Why it matters

  • The one-f-hole approach is described as helping with feedback while still projecting enough that tapping sound is audible—implying the strings still amplify and translate into the pickups.

2D) No f-hole variant / “semi-hollow but without f-holes”

Example cited

  • B.B. King’s Lucille (described as a variant of the ES-355, beginning around 1980)

Concept

  • Some designs remove the f-hole concept entirely, altering resonance/feedback behavior while keeping semi-hollow traits.

Additional semi-hollow example

  • Tele Thin line is referenced: similar to a chambered approach for an “airy” sound, paired with a single-f-hole style.

3) Chambered Guitars

Core definition (as presented)

  • Chambered designs start from solid-body starting blanks and use routed internal chambers.
  • The goal is to reduce weight while keeping the guitar lively/resonant.
  • The video calls them “technically solid body guitars” because they begin as a solid slab.

Tone / feel implications

  • Chambers add an “airy quality” and can yield tonal characteristics reminiscent of designs like a 335, since chambering affects resonance and how vibrations reach pickups.
  • A personal example is mentioned: a custom chambered guitar made in London using common tone woods (mahogany body + maple top) with large chambers visible in provided pictures.

Feedback consideration

  • Chambering is framed as helping reduce weight and potentially avoid feedback, though the video places less emphasis on feedback than in the full hollow vs. semi-hollow comparison.

Manufacturing / brand examples

  • Mentions Gretch Jet series as early chambered examples (since the 1950s).
  • Warmoth offers strat/tele bodies with ~25% less weight, claiming tonal characteristics remain.
  • Gibson weight relief: since the 1980s, Les Pauls are described as having carefully calculated drilled holes intended to maintain balance/tone while avoiding feedback.
