Hi, this is quite a specific question but I've been looking for a little rig to bring to gigs, a Littlemark III and a Markbass Traveler 102P. Then a Markbass 800 tube with a 121 and 102P cab came up for a really good price. There is no way I'd have got this brand new I know it's overkill. Great I have a the 102P and head for most gigs and an extension cab if I need it. And best of all I can carry this without breaking my back. Thing is the head is 500w into 8ohms and the cab is rated at 400w, now I know this should be OK. You wouldn't turn it up to 10 if it was a 400w amp anyway. But am I heading for disaster here, this is the configuration it will be mostly used in. Or am I just worrying for nothing?
