They might not be considered the stars of the show, but line selectors and channel switchers are definitely among the most essential workhorses of a good pedalboard. The LEF-330 ABY selector from budget guitar effects pedal maker Rowin is a versatile selector pedal, letting your signal flow from A or B to Y or vice versa. You can connect two instruments—an electric and an acoustic guitar, for example—to one amp or use the LEF-330 ABY to throw your instrument’s signal to two separate amps for a true stereo attack.

The Rowin LTL-03 METAL is a great pedal, especially if you want more 80s or 90s Metal sounds!

The pedal makes a thicker and clearer voice than the HISS.

If you like the dirty and crazy Metal sounds, the pedal can make your earphone become the gate leading to the Hell, only the Metal sounds is real on the way!

The 'Tube Drive’ pedal is an overload single block between distortion and overload, unlike the usual diode clipping circuit, it can create more dynamic margin, tube amplifier sound quality effects, subtle changes in volume and complex harmonic space and other effects.
