Product Description
The Evidence Audio ESP-RA-S is a compact, soldered 4 mm mono plug designed for players who demand maximum audio quality and minimum pedalboard footprint. Machined from brass with direct nickel plating, it delivers superior conductivity and reliability in a plug that is small enough to fit the tightest switching systems and densely packed boards.
Perfectly matched to 4 mm cables such as Evidence Audio Monorail and Blackrock, the ESP-RA-S lets you build ultra-low-profile patch leads without compromising your tone. Whether you are wiring a complex loop switcher or simply trying to squeeze one more pedal onto your board, these plugs help you reclaim space while keeping your signal path clean, clear and consistent.
With dimensions of just 23 mm by 15 mm by 8 mm, the ESP-RA-S is one of the smallest pedalboard connectors available. That tiny footprint makes angled connections possible in places where only straight plugs would fit before, opening up new layout options and freeing up valuable room behind switchers and pedals.
As part of the ESP family, this small-hole plug sits alongside larger 5 mm options and TRS variants, making it easy to build a fully integrated, professional-grade wiring solution around your preferred cable types. For players who care about both tone and tidy, efficient pedalboard design, the ESP-RA-S is a smart, future-proof choice.
High-Conductivity Brass Contacts
Brass is used for all contact points, offering higher conductivity and better sound quality than the pot metal and steel often found in cheaper connectors. This helps preserve clarity, dynamics and detail across your entire signal chain, so your pedals and amp can perform at their best.
Ultra-Compact, Low-Profile Design
Measuring only 23 mm by 15 mm by 8 mm, the ESP-RA-S is one of the smallest pedalboard plugs on the market. The tiny footprint makes it ideal for crowded pedalboards and modern switching systems where jacks sit extremely close together, helping you avoid cable clashes and messy wiring.
Optimised for 4 mm Patch Cables
The ESP-RA-S small-hole plug is designed specifically for 4 mm cable such as Evidence Audio Monorail and Blackrock. This tight mechanical fit ensures a secure solder joint and a robust, roadworthy connection that stands up to regular use and transport.
Improved Layout Options Around Switchers
Because the plugs are so compact, angled connectors can often be used where only straight plugs would previously fit. This can free up valuable space behind switchers and pedals, allowing neater cable routing and more flexible pedalboard layouts without sacrificing accessibility.
Features
- Brass Contact Construction - Utilising brass for the contact points provides higher conductivity and improved sound quality compared to low-grade pot metal or steel connectors, helping to maintain a clear, full-range signal.
- Smallest-in-Class Footprint - At just 23 mm x 15 mm x 8 mm, this plug is among the smallest available, making it ideal for tight pedal spacing and complex switching systems where every millimetre counts.
- Designed for 4 mm Cables - The small-hole format is tailored for 4 mm cables like Evidence Audio Monorail and Blackrock, ensuring a precise fit and reliable soldered connection for professional patch leads.
- Pedalboard-Friendly Angled Use - The ultra-compact housing allows angled plugs to be used in positions that previously required straight connectors, opening up cleaner routing options and saving space behind switchers on your board.
