The Splinter from JekFx is a Signal Splitter Features In short, Splinter is a two-channel switcher/blender. You can connect two external effects to this pedal and control them — turn them on/off and mix them with each other and with the clean sound in any proportion: With this connection, you can: • mix two external effects simultaneously in any proportions with the clean guitar sound (especially useful for bassists), • switch between two external effects (and turn off both effects) in a completely passive mode, i.e. without any additional impact on the sound. There are also other options for using Splinter, for example: • mixing three different signals from different sources in the desired proportions, • turning on, off, mixing effects in the amplifier loop, • cloning a signal into three copies, • switching two guitars connected to one amplifier. • using as a buffer or phase inverter. Operating principle The pedal has two operating modes — mixing (Blend) and switching (Switch) channels. The operating mode is selected by the Switch / Blend switch. If only one of the A or B LEDs is lit, the pedal is in Switch mode. If both LEDs are lit, the pedal is in Blend mode. Switch mode, channel A is active. Switch mode, channel B is active. Blend mode, both channels are active. Switch mode

Switch mode is a mode for switching between two loops. The signal from the input goes to the send of the active channel, and the signal from the return of the active channel goes to the output. The send and return of the inactive channel are not commutated with anything. The active channel is selected by the "A/B" button. In this case, the LED of the corresponding channel lights up.

All switching works on a relay and the signal circuits are completely passive. Also, there are no electronic components (resistors, capacitors, etc.) in the signal path, so the pedal does not affect the sound in the same way as if the signal was switched using just wires. Since switching is passive in Switch mode, it works in both directions (it does not matter which side is the input and which is the output).

The Bypass button is also always available, both in Switch and Blend modes it works passively (true bypass), simply connecting the Input and Output together. Blend mode In Blend mode, the device takes the signal from the input and creates three copies of it. Two copies are sent to sends A and B. Returns A and B are mixed with each other using the "Mix" potentiometer. Before this mixing, you can invert the phase of return A using the "Phase Invert" switch. After mixing returns A and B, the signal is mixed with the original input signal using the "Blend" potentiometer. In Blend mode, the signal passes through active circuits, but the bypass is still passive (true bypass). Structural diagram of the device in Blend mode: Structural diagram of Splinter in Blend mode. Use cases 1. Switching external effects, mixing external effects with each other and with clean sound. In Switch mode: the guitar signal goes through external effect A or B (depending on the position of the "A/B" button), or directly without an effect if bypass is on. In Blend mode: the guitar signal goes through external effects A and B, the outputs from them are mixed with each other using the "Mix" knob. The result is mixed with the clean guitar sound using the "Blend" knob. The output volume is adjusted using the "Level" knob. In bypass mode, the guitar signal goes directly to the amplifier, the sends are disabled. 2. Switching amplifiers. The "A/B" button switches the amplifier to which the signal goes. 3. Controlling effects in the amplifier loop. 4. Cloning the input signal - up to three copies. In this connection scheme, the device can also be used as an active buffer. 5. Switching: guitar input of the amplifier / line input of the amplifier with an external preamp. Switching with the "A/B" button. 6. Switching two guitars connected to one amplifier. Switching with the "A/B" button. 7. Connecting different "guitar + amplifier" pairs to an external effect. Switching with the "A/B" button.
