Ampeg SVT 410HLF Speakers Light Up.
Hey guy, I don't know if this is normal.
The bass player in my band has a Ampeg SVT 410HLF Cab with a Markbass Little Mark II.
Now, when he plays loud the speakers inside the cab light up. Depending on how hard/loud he plays, the speakers become brighter. I think higher tones make it happen more.
