The Wal 4-String Fretless Bass is noted for its heavy weight, approximately 12 lbs, which necessitates a thick/wide strap for comfort during extended use.

The epoxy finish on the ebony fingerboard, crafted by HG Thor, is highly praised for its quality, though there's a reported 12-year wait for his services.

The bass features versatile electronics with a built-in XLR output option, though this is mostly found in Pro series models and later.

Some owners commission sound-alike copies from luthiers familiar with Wal's designs, often starting around £6,500 for basic models.

The control cavity is notably spacious, which some owners suggest could be optimized with SMD technology for a more compact electronics board.

Owners report that the bass accommodates low action well, contributing to its playability.

The neck is described as smooth and less chunky, offering a balance between a Jazz bass and thicker neck profiles.

Buyers face a multi-year waiting period, often joining a waiting list to get on the actual waiting list due to high demand.

Despite its high price, one owner emphasized the instrument's supreme craftsmanship and unique control system, making it a standout choice among bass guitars.

The tone is described as having more mid and treble content compared to typical double humbucker setups, even without additional features like the Pick Attack switch engaged.

Owners note that the bolt-on neck design is a unique feature for its price range, contrasting with typical expectations for high-end instruments.

Despite using flatwound strings like Thomastik, achieving an old-school tone is challenging due to the distinct electronics and tonal character.

Inquiries and orders are often handled through a website form, with responses being slow due to the small team at Wal.

Some owners find that after acquiring a Wal, visiting music stores becomes less exciting, suggesting a high level of satisfaction and exclusivity.

New Wal 4-string fretless basses start at approximately £7,850, with resale values remaining solid, often comparable to used prices.
