Hartke Kickback 12 and various Basses Test

I played a while with the following basses: Ibanez Gio, Harley Benton Standard Series, Corsair mini bass by Greg Bennett, ESP F-205 LTD and my beloved double neck ULTIMA by JP Custom Guitars. The sound and video was recorded from an iPhone 12 Mini. Zero edit to the audio. You can notice the little bass Corsair (although is a passive bass) has much more power than the others only being compared with the double neck Ultima which has an active pickup. The proof is the video camera starts to shake much more while playing the Corsair and Ultima.
