Hello. I have a Peavey Max II 115. I like the amp but it has that DDT speaker protection on it. If I play a bar where the electricity is not up to the full 120 volts I have the hardest time with the DDT protection kicking in on almost all notes on the G string no matter which bass I use. Just when you dig in to solo or pop, your volume is knocked down and the power light turns from blue to red. My GK MB500 head and 2X12 cab setup don't have this problem. Is there a combo amp that won't do this? I had a Fender Rumble 350 but even on good electricity, notes on the G string would disappear. I've been considering the new Fender Rumble 200 1X15, the Carvin MB115 but I don't know if they have a built in limiter that will do the same thing. I had the new Fender Rumble 500 with the two tens for one day and the 10's couldn't handle my 5 string basses when playing with a 5 piece band that is not a heavy rock band and I don't dime the bass knob on my amps or my active basses. Maybe I got a bad one. The reason for the combo is because there are less wires to hookup, less to carry and I tilt it back. With the GK head and cab setup I had to figure out how to keep the head on the cab when tilted back. Velcro solved that. A combo amp would just be simpler. Your help would be appreciated. Thanks.
