Warwick RockBoard Flat Patch Cable 10cm Sapphire
The Warwick RockBoard Flat Patch Cable 10cm Sapphire is a high-performance audio interconnect designed specifically for pedalboard signal routing. Part of the Sapphire Series, it features a low-capacitance design, double shielding, and an ultra-flat profile to maximise space and signal integrity in compact setups.

Overview
The RockBoard Flat Patch Cable 10cm Sapphire is a premium utility cable manufactured by Warwick, designed to address common space constraints on modern pedalboards. The Sapphire Series is distinguished by its transparent design and enhanced shielding capabilities compared to standard patch leads. At 10cm in length, this specific model is intended for connecting adjacent effects pedals while maintaining a low-profile aesthetic.
Construction and Key Features
The cable utilises a multi-layered construction to ensure signal durability. The core consists of flexible copper conductors, protected by a dual-shielding system comprising braided tinned copper and an additional layer of aluminium foil. This combination is engineered to protect against external noise and electromagnetic interference.
A defining physical trait is the ultra-flat cable profile and compact, angled plugs. These allow users to position pedals in close proximity, effectively reclaiming space that would otherwise be occupied by bulky, traditional round-profile jacks.

Audio Performance and Character
Warwick describes the Sapphire Series as a low-capacitance design. In practical application, lower capacitance helps to preserve high-frequency clarity, preventing the 'tone suck' or muddy signal degradation often associated with long signal chains or inferior cabling. The gold-plated connectors are employed to prevent oxidation and ensure a reliable, high-quality contact over time.
Target Audience
This cable is suited for musicians and pedalboard enthusiasts who require a tidy, organised layout without sacrificing audio quality. It is particularly effective for those using densely packed boards where every millimetre of space is critical. Its transparent 'Sapphire' aesthetic also caters to players who value the visual presentation of their rig.
Market Comparisons
Within the wider market of studio and stage cabling, the RockBoard Sapphire occupies a niche specialized for instrument-level patching. While standard XLR cables from brands like Studiospares are suitable for balanced microphone signals, and Ernie Ball offers longer 10ft cables for instrument-to-amplifier connections, the RockBoard's flat geometry is purpose-built for pedal-to-pedal transitions. It differs from general-purpose utility cables, such as BNC antenna cables or RCA phono cables, by focusing on high-impedance guitar signals and physical space efficiency.
