AMPEG SVT-3PRO Bass Amplifier Head I tried to repair it without power, replacing various parts, but I gave up after exactly 3 years since I bought it because I didn't have time. For those who can repair it, or for parts! The sound is the classic SVT sound, without a doubt. I think it's a must-have for any bassist who dreams of owning one. Power cable not included.
