25 burgers will take care of the food input.... output might be an issue =)
Congratulations on the bass- it took me awhile to get used to the filters too- my recommendation is to turn the Q's on when you're learning. Having them on made it easier for me to hear the slight changes that resulted from tiny turns of the filter. I rarely play w/ my Q's on now, but I usually use them to help me find the tone range I'm looking for.
Have fun!
