The Compact Problem Solver for Guitarists!
This little white box has become an essential part of my pedalboard setup! As someone who frequently switches between different guitar tones during performances, this 3-in-1 pedal has simplified my signal chain dramatically. 🎸The AB line selection function is brilliantly implemented - I can now instantly switch between my humbucker and single-coil guitars without any awkward pauses or cable swapping. The footswitch feels solid and responsive, making mid-song transitions seamless.The loop function is equally impressive for toggling my effects chain on/off. Instead of tap dancing across multiple pedals, I can now activate or bypass my entire modulation section with a single stomp. This has made my live performances much more fluid.The buffer function deserves special mention - it's solved my tone loss issues when running longer cables. My signal now maintains clarity and brightness even with a complex pedalboard setup. The true bypass feature ensures my guitar's natural tone remains intact when the pedal is off.**Pros:**- Incredibly versatile 3-in-1 functionality- Compact design that saves pedalboard space- Very low noise floor compared to similar units- Solid build quality with responsive footswitch- Simple, intuitive controls with LED indicators- Works perfectly with standard 9V power supplies**Cons:**- Switching between functions requires bending down to use the toggle switches- No battery compartment (DC power only)- Could use clearer labeling for first-time users- Footswitch is slightly louder than premium brands- Limited user manual (though operation is straightforward)At just 300 grams, it's remarkably lightweight yet feels sturdy enough for regular gigging. The metal housing inspires confidence that it will withstand years of stage use.I've tested it extensively with both active and passive pickups, and it handles both beautifully with no discernible tone coloration. The gear shift switch for controlling two buffer lines is a clever feature that guitarists with complex setups will appreciate.Perfect for anyone looking to streamline their rig while enhancing their signal path. This pedal offers genuine utility rather than just another sound effect! 🤘

Multi-Functional Guitar Effect Pedal.
You can easily switch between A and B lines with a single footswitch. The loop feature is also turned on and off with a single touch. The buffer function of both lines can be controlled with the gear change switch. Thanks to the true bypass feature, it preserves the original tone of the instrument. The signal quality is very good, I have not experienced any distortion. The structure is quite solid, it seems durable enough for stage use. It is easy to install and use. The power supply connection is compatible with the standard 9V DC input. It is compact in size, it does not take up much space on the pedalboard. The LED indicators clearly show which mode is active.

Great for connecting multiple effects
This is a nice addition for any guitarist/bassist that uses a lot of effects. It allows you to organise the cables neatly and avoid the mess on your pedal board. The quality is very good. The enclosure is made of solid metal and the sound quality is good as well. At such an affordable price point I had zero complaints. I highly recommend this product.

Severe cross talk
Gave this two stars as the box is well made, sturdy and looks good.However......I get severe amounts of crosstalk across the connections. I use connection 1 for the headphone output from my USB audio interface. And have tried connections 2, 3 and 4 for a line in for my guitar which then goes to the audio interface. WHenever i record in my DAW i get the signal from the headphones stamped all over the audio signal of the guitar.If I take this box out of the equation and plug headphones and guitar directly in to the audio interface, no issues whatsoever. Its only adding this box in to the chain where the issue arises.I'm going to keep it and open it up and see whats going off, it feels like the ground of all 4 inputs/outputs is common or something which is causing the issue. Maybe if this was seperated it will resolve the issue.Its a shame as this fits perfect in to my setup and makes it so convenient not having to plug in to the back of the audio interface all the time.
