1960s Gibson "Custom Modified" Fretless Bass – Quirky, Unique & Super Playable!

If you are looking for a standard, run-of-the-mill vintage piece, this isn't it. But if you appreciate incredible vintage vibe, unique custom craftsmanship, and an instrument that stands out in both looks and tone, this 1960s Gibson bass is an absolute gem.

Starting life in the 1960s (likely as an EB-0 or a similar short-scale platform, or potentially a 6-string bass), this instrument has been converted into a fretless player’s dream. Someone put an immense amount of thought, time, and serious work into modifying this bass, resulting in a super quirky, highly versatile, and genuinely awesome instrument that plays great and sounds fantastic.

The Construction & Visuals

The core of this bass is its original 1960s Gibson body and neck, featuring a beautiful genuine Brazilian rosewood fingerboard that feels incredible under the fingers. The body finish is entirely unique: a previous owner stained and painted the original wood to mimic a striking, multi-layer Alembic-style look. It gives the bass a high-end, boutique 1970s hippy-sandwich aesthetic that looks killer on stage.

Upgraded Hardware & Electronics

This bass was built to be played, featuring heavy-duty hardware upgrades and a massive tonal palette:

• Pickups: It features a triple-pickup configuration, one 1960s Gibson pickup for that deep, vintage thump, paired with two added P-Bass style split-coil pickups for incredible bite, growl, and midrange clarity.
• Controls: The wiring has been completely customized to manage this powerhouse trio. It is laid out with three individual on/off toggle switches (one for each pickup), three independent volume knobs, and one master tone knob. The sonic combinations are virtually endless.
• Hardware: Upgraded with a high-mass brass nut and a matching brass bridge for massive sustain and a bright, clear attack. The tuners have been upgraded to premium Schaller tuners for rock-solid tuning stability (note: one of the tuner machines hass gotten a little bit crooked over time , but it functions perfectly).

Tone and Playability

Despite all the modifications—or rather, because of them—this bass is a phenomenal tool for the studio or the stage. The fretless Brazilian rosewood board offers a smooth, singing "mwah" factor, while the combination of the original Gibson mudbucker vibe and the punchy P-bass coils lets you dial in everything from deep dub reggae to aggressive rock growl. It is highly usable, structurally sound, and possesses a vibe you simply cannot buy off a modern assembly line.

If you love unique vintage history, player-grade mojo, and quirky instruments that punch way above their weight class, this custom 1960s Gibson conversion is ready for its next chapter.
