So, the story has a happy (but expensive) ending. But, the rig's quiet, and the pedals are all working well. I actually just unscrewed all of the Furman electronics from the board, and I now have a very expensive piece of plastic with foot pegs and female velcro. Successfully powering my Nova Delay at 12V/300mA, my MXR 10-band and Slash Wah at 18V, and my OCD, Tuner, and Compressor at 9V.įortunately, this was both a curse and a blessing: After solving the hum, I was able to return the ISP decimator as it was not needed (and was introducing a hum of its own?), so that counted towards credit for two ISO-5s.
Went to GC and bought a pair of Voodoo Lab ISO-5's. Ran direct from guitar to tuner and amp effects loop direct through my pedals. I ran this morning's service with wall warts into power strips for my 18v and 12v pedals, and 9v batteries in my 9v stompboxes. I verified ground continuity from the AC outlets, and they made my wall warts hum for some reason.
I even fully removed the patch bays from the unit and they still introduced a hum into my chain. Using *anything* from that board (patch bays, AC outlets, or DC outlets) introduced an annoying hum into my signal path.
One good yank on a guitar cord can fllex the plastic jack and cause a solder connection to crack.įinal update: I used my buddy's Furman SPB-8 and it had all the same problems as mine.
Lugs suggest they are PC mount jacks and they pretty much suck for durability. I suggest you open the unit and check the jacks solder connections. I think its just a ground problem at this point. Theres nothing in the specs to suggest that its anything but passive connections so Those items would require a DC supply and if that DC supply is going bad passing AC ZU VERKAUFEN Up for sale is Furman SPB-8 Stereo Pedal Board with Power Conditioner. Maybe theres a buffered amp in there that is used to boost the signal to filter noise or a noise gate. FURMAN SPB-8 STEREO Pedal Board with Power Conditioner SPB8 - Works Great - EUR 101,76. If they do it would be a rediculous arrangement because it would influence the Maybe they put filtering on the guitar jacks? Would be any voltage applied to the patchbay jacks if they are passive. Portion may connect to to create the issue. The plugs are switched so I'm not sure what the patch bay The jacks may be PC mount and you have aĬracked solder joint. With the furman or the cords connecting it to the amp. So be advised.If the amp doesnt hum plugged in direct, then you have a problem If only Furman has/had a stronger quality control, since I've read the same issue happening with (especially) this model. It does its job well - everything works better since I use it less noise in the system and the pull-out lights are really cool (the dimmer is also very flimsy) and I'm glad I purchased it if it weren't for this nuisance. It's still low and can only be heard when there are no other noises but if for example I move my PC (or other rack gear connected to the PL-8C E), even by a centimeter, it goes to irritating levels with an added constant booming tone and I have to adjust the PC case to find a sweet spot for it to disappear. It makes the unwarned power outages a real threat it not to mention to my whole system if it won't turn on again (the power of my hits to its top need to increase each time in order to turn it on) - the local power (distribution) company managed to spike out my previous monitors, a hard drive and half of my sound card due to its notorious voltage jumps.Īnother issue is that a low buzz-like hum is getting louder and louder (which also existed on the first day of its operation), coming from where the fuse is. There is no way of powering on the unit once it's been turned off other than in barbaric ways aka shaking it or the good old American slap-on-it so I keep it on at all times. Thomann fixed it - worked for about 6 months only for it to happen again, even after turning it off every 2 or 3 days.
I've sent the unit back to be repaired after a year of its purchase - the power button (felt flimsy anyway) failed and the unit wouldn't turn on.
