Choosing between these ESP LTD instruments is primarily a role decision: the TL6 Thinline is an acoustic-electric guitar, while the F-4 Black Metal is an electric bass guitar. Their listed prices are also $824 apart, but the more useful question is which instrument belongs in the part you need to play.
Quick verdict
Choose the ESP LTD TL6 Thinline when you want an acoustic-electric guitar with an Acoustic Resonant Chamber, Fishman pickup technology, and a custom pickguard look. Its used condition includes stated cosmetic wear, making appearance an important part of the decision.
Choose the ESP LTD F-4 Black Metal when the assignment is electric bass and you want the F Series' black-satin Black Metal presentation. It is listed as new and adds a neck-through-body design with a 35-inch scale.

Where each instrument wins
ESP LTD TL6 Thinline: acoustic-electric flexibility
The TL6 is the fitting choice for guitar-focused parts that call for an acoustic-electric format. Its soundhole-mounted rotary controls for volume and tone keep the controls close to the pickup system, while the mahogany body, spruce top, and rosewood fingerboard give this particular guitar a clearly defined build. The custom gold tuner and white pickguard details also make it the more visually individual of the two.
ESP LTD F-4 Black Metal: bass-focused construction
The F-4 wins when the role is firmly electric bass. Its solid-body format, 24 frets, neck-through-body construction, and 35-inch scale establish a distinctly different instrument category from the TL6. The all-black design theme, including black hardware and a fingerboard without inlays, suits players looking for the specific Black Metal-series aesthetic.
Product notes
ESP LTD TL6 Thinline AcousticElectric Custom Guitar Black/Gold White Pick Guard
The ESP LTD TL6 Thinline is a good match for a guitarist who wants an acoustic-electric format with discrete soundhole-mounted volume and tone controls. Its Acoustic Resonant Chamber, Fishman Sonicore pickup, mahogany body, spruce top, rosewood fingerboard, set neck, NuBone-XB nut and saddle, and Wilkinson tuners make its configuration notably detailed. The custom plexiglass pickguard and gold Wilkinson 18:1 keystone tuners give it an individualized visual direction. Its limitation is condition: this guitar is used, with stated swirls, scratches, and scuffs mainly on the back. Choose it when that played-in cosmetic condition suits the role and the custom appearance appeals.
ESP LTD F-4 Black Metal Electric Bass Guitar Black Satin Brand New F4
The ESP LTD F-4 Black Metal suits the player seeking a solid-body electric bass with a dark black-satin presentation. Its listed construction includes a neck-through body, 35-inch scale, Macassar ebony fingerboard without inlays, glow-in-the-dark side markers, and a single pickup. These details create a stripped-back Black Metal-series look, while the 24-fret specification defines the instrument's layout. The clear limitation is the USD 1,299.00 listed price, which places it at the upper end of this two-instrument comparison. Make it the choice when the bass role, long scale, and no-inlay visual design are the priorities.
Final choice by use case
Pick the ESP LTD TL6 Thinline for an acoustic-electric guitar part, particularly if its custom pickguard and used cosmetic character fit your preference. Pick the ESP LTD F-4 Black Metal for an electric bass role where its long-scale, neck-through construction and Black Metal presentation are the better match.
