How did Bon Jovi create the guitar effect in Living on a Prayer?

The guitar effect in "Livin' on a Prayer" by Bon Jovi is created using a variety of techniques. The main effect is a sustained, distorted sound that provides a powerful backing to the song. This is achieved using a combination of distortion pedals, a wah-wah pedal, and a tremolo arm. The distortion pedals add grit and sustain to the guitar's sound, while the wah-wah pedal adds a vocal-like quality. The tremolo arm is used to create a pulsating effect that adds movement and interest to the sound.

In addition to these effects, Bon Jovi also used a "harmonizer" pedal to create the signature double-tracked guitar sound in the song. This pedal splits the guitar signal into two separate signals, one of which is played at a slightly higher or lower pitch than the other. This creates a rich, full sound that adds depth and texture to the guitar part.

The combination of these effects creates a unique and memorable guitar sound that has become synonymous with the song "Livin' on a Prayer." It is a perfect example of how Bon Jovi's creative use of effects can transform a simple song into a classic rock anthem.
