Hello there. I already made this question on the bass guitar forum but i'm looking for all information available please.... I just bought an ampeg b100 r amp.... It was cheap and i like the tone on it, fat and good low end.....now comes the problem....when i was cheking out the back of the amp, inside i found 2 cardboard cilinders.......since they were loose inside, not stucked in any way, i took them out..... well. somehow i got the feeling that they belong inside, so i made this question on the bass guitar forum since its a bass amp....they told me that these 2 cilinders are important and they should be put back in...... my question is..... is there any special position??? i dont think so since they were loose inside the amp and they would bounce with any moviment carrying the amp or so... other thing....when took them out, they got a little scratched.....does it gonna damage the sound??? any sugestions welcome thanks in advance.....
