E-guitar adapter cable Omnitronic 6.3mm jack to 3.5mm (model 13063458)

The Omnitronic E-guitar adapter cable connects a standard 6.3 mm (1/4") guitar output to a 3.5 mm input, enabling direct connection of headphones, small mixers, portable recorders or audio interfaces to instruments with a full-size jack. The cable is designed to provide a compact and convenient link for practice, recording and live situations where space or input type requires a smaller connector.

Advantages

This adapter cable offers a simple, plug-and-play solution to bridge size and connector type differences between electric guitars and devices with 3.5 mm inputs. The compact form reduces cable clutter and simplifies setup when using headphones or portable equipment. Durable connectors ensure consistent contact and a reliable signal path during repeated use.

Suitable for

• Connecting electric guitars to headphones for silent practice
• Linking guitar output to portable recorders or field recorders
• Feeding small mixers or consumer audio interfaces with a 3.5 mm input
• Temporary stage or rehearsal setups where compact cabling is needed

Key specifications

• Connector A: 6.3 mm (1/4") mono or stereo jack depending on instrument output
• Connector B: 3.5 mm (1/8") jack for headphones or line-level inputs
• Cable length: short, low-profile adapter cable suitable for close connections
• Construction: molded connector housings for strain relief and durability
• Signal type: analog audio transmission for instrument-level signals

How to use

Insert the 6.3 mm end into the guitar's output jack and plug the 3.5 mm end into the headphone socket, recorder input or mixer channel. Ensure the instrument and the receiving device are powered down or volume is low while connecting to avoid loud transients. After connection, gradually increase volumes on the guitar and the receiving device to achieve the desired listening or recording level.

Usage recommendations

Use the adapter for short, in-line connections and avoid placing heavy tension on the cable or connectors. For unbalanced instrument signals, verify compatibility with the target device (headphone vs. line-level input) and adjust levels accordingly. Store the adapter in a dry place and disconnect when not in use to prolong connector life.
