Hey All! So very strange thing happened yesterday. We usually practice in a very small space - Drums, Guitar, Bass, Vocals. Yesterday was the exception, we had extra guitar player with crap load of pedals and 30watt head, nothing unusual, but his was the only major change to our set up. I had plugged in as usual in a power bar (cheap) - I run passive bass - > 4 pedals - >kg mb800 - > neo410 8ohm. Started warming up, and all of a sudden my sound level dropped a lot! and i started hearing a lot of braking up and distortion. First thought blown speakers (cab and head are 3 month old with very little use - usually volume is not over 9 o'clock with drive at noon, that little head is LOUD!). I powered everything down, disconnected pedal board - bass straight into the head - same. Bummer. Power down, connected head into different power outlet - it in started working! everything crystal clear and punchy for about 10min. Then same again. That night i kind of gave up, but weird thing i had noticed when 3 of us - guitar , guitar , bass would start to play at the same time, sound would clean up... and it would sound ok. I count find any logical pattern to this issue. It would come and go, so not the cab i assume... As soon as I got home - set everything up, except pedals - played at a low volume for about 30 min - everything is perfect! Even played thru head on its own (solid state is fine that way with headphones - perfect) What might that have been??? Bad power? ... I know the other band was rehearsing in the room next to us, but this never happened. I am just afraid if this will happen at the venue /gig. Any one would recommend power conditioner? I dont have a rack, so the floor one i guess? Thanks lads!
