Fender Rumble 15 - recommended settings? | TalkBass.com
Jan 07, 2013 · Congrats & Welcome. The Rumble 15 is actually an excellent starter amp. Start with all tone controls at 12 o'clock high (flat). Find a comfortable volume level about 1/3 to 1/2. Start with the midrange control. This is the very easiest frequency range to hear. Turn it all the way down. Slowly. Note the sonic subtraction. Now turn it all the way up. Slowly.
