Getting the right electric guitar tone is a hobby for some and a lifelong obsession for many. It requires the ability to experiment with a wide range of guitar amplifier settings. Connecting two guitar amps together is a technique that many veteran guitar players use to expand their sound. This technique allows you the ability to use two different-sounding amplifiers to create a fuller guitar tone.
Buy a Y-cable with ¼-inch male end and two ¼-inch female ends. You can purchase these cables anywhere music instruments or audio connectors and adaptors are sold.
Connect a ¼-inch instrument cable into each amplifiers ¼-inch input jack.
Connect the ¼-inch instrument cables from each amp into a ¼-inch female end of the Y-cable.
Connect a ¼-inch instrument cable to your guitar's input jack, then connect the other end of the instrument cable. Then connect the other end of the instrument cable into the male-to-male ¼-inch adaptor.
Connect the male end of the Y-cable to the available end of the male-to-male ¼-inch adaptor, set the volume knobs on the amplifiers to one or two, then turn on your amplifier to test.
Before turning your amp on, be sure the volume knobs on your amps are turned down low. This prevents loud feedback and protects your speakers from being blown.
