Hello Hive Mind,
I need some help / advice regarding my pedal board. During lockdown in 2020 I decided to upgrade my old board and add in a few new pedals, namely the envelope filter, compressor and mono synth. I also upgraded the power supply to the fuel tank.
It sounded fine to begin with, but when I was listening through headphones I could hear a distinct 'hum' coming from somewhere - not particularly noticeable when listening just through the amp.
I took my bass (a Sire U5) to a Luthier who checked all the connections and put shielding inside the cavities.... still no luck!
I then changed the power supply to the 1-spot and disconnected all the pedals other than the essential ones which worked for a while until a gig this weekend when....... the buzzing came back. It wasn't there when I was touched the strings but otherwise..... yep you guessed it.......it was sounding like a swarm of p*ssed off wasps.
I really don't know what the issue is - whether its a specific pedal, a grounding issue or an electrical supply issue. I was fuming at the weekend at the gig and if i'm honest, it felt really amateurish with me apologising for the umpteenth time to band mates with "sorry about the buzzing, that's me again".
I don't quite know where to go with this one - any ideas or suggestions would be greatly appreciated! Pedalboard pic attached
thanks
