I am fairly new to bass playing, better yet playing in general. I got a Fender Rumbler 100 couple months ago and used it with my beginners fender bass (passive pickups). Last week i bought an ESP B205 with SB-5 pickups. I plugged it into my rumbler 100 and the amp started smoking. Call tech support and they told me there is a switch to use that amp with active pickups. But dont see it. I have it on one of my older prometheus amps but not the rumbler. PLEASE HELP. Can i use the ESP B205 with my rumbler 100 amp?
