The Mogami PLATINUM GUITAR-40R is a 40-foot unbalanced instrument cable with one straight 1/4-inch TS plug and one right-angle 1/4-inch TS plug. It is made for connecting an electric guitar, bass, keyboard, or similar instrument to an amplifier, pedalboard, or compatible unbalanced input. The extended length gives players room to move while maintaining a direct instrument-level connection.
This cable is intended for musicians who need a long run without using a basic utility cable that may add handling noise or affect high-frequency response. Its low-capacitance cable design is engineered for signal clarity in high-impedance instrument applications. The right-angle connector can be useful with side-mounted or recessed instrument output jacks.
Mogami uses a 20 AWG oxygen-free copper center conductor, cellular polyethylene insulation, and a composite braid shield structure in its Platinum guitar cable construction. A conductive PVC layer is used to help minimize handling noise. The result is a shielded coaxial-style cable built for unbalanced instrument signal paths.
The PLATINUM GUITAR-40R uses gold-plated contacts and copper-core G&H plugs, with a straight plug at one end and a 90-degree plug at the other. Either end can be used at the instrument or amplifier depending on clearance and cable-routing needs. Its black PVC outer jacket is designed to remain flexible for stage and studio use.
Use this cable as the primary lead between an instrument and the first device in its signal chain, such as a pedal, DI-compatible instrument input, or guitar amplifier. It is not a speaker cable and should not be used between an amplifier head and a speaker cabinet. For a complete rig, pair it with equipment that accepts standard 1/4-inch TS instrument connections.
Key Features
- 40-Foot Length: Provides extended reach for stage, rehearsal, and studio setups.
- Straight and Right-Angle TS Plugs: Supports flexible routing around instrument and amplifier jacks.
- 20 AWG OFC Conductor: Uses oxygen-free copper for the cable's center conductor.
- Low Capacitance Design: Helps retain high-frequency detail over a long instrument run.
- Conductive PVC Layer: Helps reduce handling-related cable noise during use.
- Lifetime Warranty: Factory-assembled Mogami cables are covered for the original purchaser.
Design & Installation
The PLATINUM GUITAR-40R is built around Mogami W3368 low-capacitance guitar cable, with a 20 AWG oxygen-free copper conductor, cellular polyethylene insulation, composite braid shielding, conductive PVC, and a black PVC jacket. The cable has an 8.0 mm outer diameter and uses gold-plated-contact copper-core plugs. One connector is straight and the other is a right-angle 1/4-inch TS plug.
Connect the cable between an instrument and a compatible 1/4-inch TS instrument input. Select the right-angle end for the jack location that benefits most from reduced connector protrusion, then route the cable to avoid sharp bends and repeated twisting. Use an over-under coiling method for storage, and use a dedicated speaker cable rather than this instrument cable for amplifier-to-cabinet connections.

Will this work with my electric guitar or bass?
Yes, it is an unbalanced 1/4-inch TS instrument cable for compatible electric guitars, basses, keyboards, pedals, and instrument amplifiers. Check that both devices use standard 1/4-inch TS instrument connections.
Which end should connect to my guitar?
The cable has one straight and one right-angle 1/4-inch TS connector, and either can be used at the instrument. Choose the right-angle end when it offers better clearance at your instrument's output jack.
Can I use it between an amp head and speaker cabinet?
No. Mogami advises against using a guitar cable for an amplifier-to-speaker-cabinet connection because speaker cables have different conductor requirements. Use a dedicated speaker cable for that application.
Does this cable have a silent-switching plug?
No silent plug is specified for the PLATINUM GUITAR-40R configuration. The right-angle and straight ends use copper-core plugs with gold-plated contacts.
What is included with the cable?
The package includes the 40-foot Mogami PLATINUM GUITAR-40R instrument cable. It is covered by Mogami's lifetime "No Excuses" warranty for the original purchaser when it is a factory-assembled cable.
Is 40 feet suitable for a guitar setup?
It is suited to players who need extended stage or studio reach. Mogami notes that shorter guitar cables are generally preferable when practical, but its Platinum guitar cables are designed for longer runs.
