Virtual rhythm section (piano/bass/drums) to play along with.

Metronome/Tuner/Drone for daily practice.

To slow down and isolate those problem areas (solos and melodies) you are trying to transcribe.

Drum loops with real drum sounds to play your scales, tunes, and licks with

Jazz fake book with hundreds of jazz “standards” you want to be familiar with.
