About This Item
Description
SIS (Screw-In Solderless) plugs let you build and rebuild Monorail patch cables without a soldering iron. This listing is the Straight, 10-pack version.
Choose the right version
This is a 10-pack of Straight SIS plugs. Angled plugs keep a low profile for tight pedal spacing; Straight plugs suit inline and end connections. All SIS plugs are designed for Evidence Audio Monorail patch cable. The straight SIS plug has a nickel finish.
Why players choose the SIS Plug
Pedalboard builders choose SIS plugs to build and rebuild without solder and avoid signal failures in the middle of a song. The inside of the tip is machined with threads that cut and re-shape the soft copper of the Monorail cable, forming an airtight connection that is in many ways better than a soldered joint.
Assembly is straightforward and satisfying to do at home. One essential step — remove the thin black conductive skin from around the white insulation during assembly (leaving it on can short the cable and cause tone or volume loss), then do a quick continuity check before you play.
Assembly tips
- Attach the first plug to the full length of cable, then measure, cut and attach the second plug — don't cut the cable into pieces first.
- Wear rubber gloves for grip and to protect your fingers when tightening.
- Straight plug: push the cable in until the core seats, then rotate the plug about 10–12 full turns; the jacket only needs to enter a few millimeters.
- A screwed connection can be taken apart and rebuilt, so cables can be shortened or re-routed as the board changes.
How it compares
SIS plugs are the solderless (screw-in) option for Monorail cable; the ESP plug is the soldered pancake alternative.
Key features
- Patented screw-in solderless 1/4" TS (mono) phone plug designed for Evidence Audio Monorail cable
- Machined threaded tip; a harder brass core cuts into the copper for an airtight connection that also seals the jacket
- No soldering iron needed; plugs can be removed and reconnected
- Sold in a pack of 10
- Available in Straight and Angled (Right-Angle) orientations
Compatibility
- Evidence Audio Monorail patch cable: 20 AWG solid-core IGL copper center conductor, parallel-run shield with 98% coverage, low-capacitance coaxial geometry, carbon-loaded jacket against handling noise
- Mono (TS) connections between pedals, tuners and pedalboard patch points

FAQ
Is it hard to assemble? No — assembly is straightforward and satisfying at home. The plug screws onto the cable and its threaded tip forms the connection, with no soldering required.
What is the one step I must not skip? Remove the thin black conductive skin around the white insulation — leaving it on can short the cable and cause tone or volume loss — then do a quick continuity check before you play.
Straight or Angled? Angled (Right-Angle) plugs keep a low profile for tight pedal spacing; Straight plugs suit inline runs and end connections.
Can I reuse the plugs? Yes. The connection is screwed, not soldered, so a plug can be removed and fitted again when you rebuild a cable.
Mono or stereo? Mono: the SIS is a 1/4" TS plug for single-conductor patch cable such as Monorail.
Is cable included? No, this pack contains plugs only; Monorail cable is sold separately.
