Gecko 5 String Bass Body Features

This body features an extended upper horn for perfect balance with playing with a strap and a small lower horn to catch your thigh when playing seated. The deep heel-less extended neck joint gives superb access to all 24 frets. The neck bolts are laid out in an asymmetrical pattern for maximum stability and sustain, they are secured in the body with custom recessed steel washers.

The well-designed rear-access control cavity features a built-in compartment for up to two batteries as well as plenty of room for controls and a custom recessed area for neat installation of an active preamp. Precisely crafted in every detail, the cavity cover even screws on with machine screws and threaded brass inserts that won’t strip out.

Two Pickup Routing Options

The Gecko works well as a One or Two pickup bass as seen below. Choose the pickup routing to match your tone needs and playing style. Two pickups offer broad frequency response and a wider variety of tones, while a single pickup can deliver a more focused midrange sound and leave more room to dig in under the strings.

Each image below shows the pickup routing and lists the type of pickup that routing can accommodate.

* Pickup routing options available but not shown below are the 6-string ASB2-6 (P4) & ASB-6 (EMG45).

Gecko Features

The Gecko bass series is specifically designed to bring professional bassists their most desired features and functions in any degree of assembly that suits their finances or abilities. These premium quality pieces (and they truly are premium) incorporate woods, construction, and design elements found only on top of the line instruments retailing for $2500 and more.

Depending upon what features you choose, a Gecko may be assembled for less than half this price. Gecko components have been designed and manufactured with ease of assembly in mind. You can do this! Be assured, you won’t find a more exceptional bass for your hard-earned money, anywhere.

All standard Gecko bass necks feature 5-piece laminated construction (using bloodwood or purpleheart for the lam depending on availability), 35" scale and 24 fret fretboards. Each neck has been fine sanded, and dipped in a penetrating sealer, ready for final spray finishing. Through holes are drilled .551" (14mm) for Gotoh tuning machines. Neck mounting holes are also predrilled. Choose from our list of fretwire types to install. A black truss rod cover and screws are provided. Please see the paint & finish section for finishing options. If you prefer a blank fretboard, we can omit the Gecko inlay for an additional $35.

Example of a Maple Laminate Neck

Example of a Wenge Laminate Neck

The Gecko series bass necks feature an asymmetric neck profile for a more comfortable, fast feeling. These necks "feel" thin, but retain sufficient bulk for strength and tone. The asymmetric neck profile keeps perceived neck bulk down for maximum hand comfort and to create a thinner, fast feeling neck. The bass side of the neck is thicker, with the treble side being thinner. Your thumb will find easy reference as your hand glides up and down the neck. This is a very comfortable neck to play.

Fretless Line Option

NOTE: All Gecko necks are available fretted or fretless at the same price.Unlined fretless necks have the side position markers moved to the exact fret positions, rather than between them.

Contrasting strips of wood inlaid into the fretless fretboard at the usual fret positions. Maple lines are used in dark fretboard woods, black lines are used on maple. Additional $105
