21 ft angled-to-straight instrument cable
The Monster CLAS-I-21A WW is a professional instrument cable built for electric guitars, basses and keyboards. It runs 21 ft from an angled 1/4" plug to a straight 1/4" plug. All-metal connectors and a tough outer jacket are designed for stage and studio use. The cable was first listed by the manufacturer in 2023.
Check your jack orientation and reach
Verify that your instrument accepts an angled 1/4" plug without fouling adjacent controls or a strap button. Ensure the 21 ft length covers the distance to your amp, pedalboard or interface without excess slack. The 90% copper spiral wrap shielding helps reject interference, so confirm your signal chain benefits from a shielded mono lead.
Suits players needing a durable angled lead
This cable fits musicians who want a rugged, shielded connection with an angled plug at the instrument end. It is not for setups that require a straight plug at both ends, balanced TRS wiring, or a different length. Buyers needing a right-angle plug at the amp side or a shorter run for desktop recording should look elsewhere.
