Detail 01
Mono, not stereo
Only tip and sleeve are wired. A TRS plug's ring contact is not carried through.

Independent shopping perspective
A gold-plated 1/4" mono Y adapter: one male plug branches into two female jacks. For splitting or merging one signal path at the jack.

Strong match

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Only tip and sleeve are wired. A TRS plug's ring contact is not carried through.
Detail 02
The male end plugs into your gear; two cables branch out from it. It does not join two cables.
Detail 03
The two destinations load each other. Expect some level drop and dulled highs with high-impedance sources like passive pickups.
Detail 04
Resists tarnish on connections left plugged in for months. No audible difference on a fresh, clean nickel jack.
Detail 05
Two cables hang off a jack-mounted adapter. That leverage is on the jack, not on a cable.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Yes, though a passive split means both amps load the pickup. You may lose a little level and top end. A buffer or ABY box avoids that.
No. It is wired mono, so only one channel passes. A stereo signal loses the ring conductor.
Electrically it works, but the two instruments load each other and there is no isolation. Volume interaction and hum are common.
For sound, no. It matters for corrosion resistance in humid rooms or on connections you rarely unplug.
