| Custom Cabs

I have recently built some custom cabs with the help of a friend who knows a bit about the science behind the sound.
Basically, I've now two rather large cabs for a Boogie Walkabout head I have, but the other night during a gig I was pushing the amp pretty hard and I was getting a bit of a distorted noise. I wasn't sure if this is due to the amp (valves might need replaced, but not sure how to know this, one does seem to be glowing more than the other, I assume this is not normal, and ideas, as valves are new to me), or maybe some of the joints in the cabs aren't the best, any ideas on how I can be sure?
Also (long winded for a first post I know!!), but when I plug into the DI from the amp, I sometimes get a buzz that carries through the whole PA system. Sometimes this doesn't happen and sometimes it does, deoending on the venue. Initially I thought it was the earth in my bass, but I've earthed it and also put some foil over the back of the backplate to try and reduce anything getting in, but sometimes the noises are still there, I think I pick up a lot of lights and stuff.
I play a Warwick Corvette Standard Fretless bass if that's of any use to you.
Hope someone can help. I'll give all the info I can if you need more.
Cheers |
