He is playing an electric bass. This doesn’t tell you it will work for you. If it says it’s also designed for acoustic instrument pickups hopefully it’s not just advertising. It may have a separate input. An ABG doesn’t provide signal the same way. Piezo pickup through battery powered preamp. Can sound good can sound so so. If the preamp in the combo/amp head isn’t buffering the signal from your ABG properly you will not have the sound you desire. If in doubt plug an ABG into many amps at your local GC. They will sound not so good. Plug in an electric bass and boom, good.
An amp designed for acoustic instruments will accept the impedance (not speaker ohms) and voltage and give you the accurate signal from your ABG. Upright bassists struggled for decades with this.
Acoustic guitarists did as well. Throw a Fishman under the saddle and plug into a PA or guitar amp and it sounded really bad. A decade + ago Fishman began buffering their own piezo pickups for acoustic guitars so no additional pedals were needed.
You didn't quote anything but I guess thats in response to the PJB video I posted?
with the electric.
