ampeg svt 410hlf problem?

[herman]

i had a rehearsal last night with my fairly new svt 410hlf, all was going well until our guitarist said he could see the top two speakers in my cab `light up` how right he was!! when i played finger style it was fine, then played some slap and popping and the outside of the top speakers around the speaker frame area would light up when i popped the D and G strings on my bass!!! the cab is made in vietnam, would anyone know if this is a major problem, am i harming the speakers?

many thanks, herman.

if I remember correctly, there is a bulb in the curcuit that switches on if you are pushing the speakers too hard. The bulb is used as a fuse which will burn out and kill the curcuit before the cab gets damaged. The bulb will start to glow to tell you it is near burning out point.

Try turning down the bass tone control and/or the master volume when you slap/pop.
