Did my pedalboard damage my guitar or amp?

[NYC]

I just setup a new pedalboard. A few overdrive pedals, volume pedal, wah and a couple of delays.

it was playing perfectly. Then I just turned it on again and it wasn’t feeding a signal into the amp so I started looking around and realized that one of the last pedals in the chain (boss digital delay) wasn’t powering on. So, I found where it plugs into my pedal power supply (voodoolabs new isolated power unit - safe) and I unplugged it and plugged it back in.

when u did that the amp made a loud pop noise and there was a strange hum that was new when I started playing my guitar. So I unplugged it and grabbed a different guitar to see if it was the guitar, the new guitar wasn’t humming but my amp was responding very very strange to the volume control on the guitar - the volume control didn’t cut off the volume as it normally does rather it made it way down to 1 then cut and also the volume control impacted tone dramatically - very erratic. Remind you, this is a new fresh guitar and the pedalboard is gone not in the signal anymore just fresh new guitar Into amp.

tha amp is a regularly serviced 1964 twin reverb and it has been running perfectly.

any idea what may have happened here?

did I damage my guitars electronics somehow? That would be worst case…

did I damage the amp by unplugging a pedal’s power??

did I damage the pedals? Any ideas?

i turned it all off an haven’t tried anyrhunf else yet

Likely you caused a voltage spike that fried some components. Keep the amp unplugged. Dont power it on. Take it to a tech.

Fried components in the amplifier?

is if possible that I fried anything in my guitar? That would be extremely terrible….

unfamiliar if that’s even possible to send a signal that direction towards the guitar but, is if?

I don’t have another amp to try the guitar on so I’m nervous haha

[omphalopsychos]

Guitar is probably fine.

I turned the amp back on it’s sounding normal now in general but does have an idle humming (static-ish) noise that it didn’t have before.

this old twin is nice at times but wow so sensitive it’s getting thrown off all the time

it seems like guitars are ok

Those old Twins have a tendency to pop when turned on/off but the other issues are definitely not normal.

Always make sure you put the amp on standby when you are messing around with pedalboard issues, a loud pop when you unplug the power to a pedal is normal.

No way this could harm the guitar that I know of.

Possibly an issue arose in the amp at the same time, may or may not be related.

Any time you unplug/plug in a 1/4" jack, you short the circuit momentarily. That shouldn't harm anything if the circuit is at line level, but anything is possible, I suppose. A silent plug on an instrument cable shorts the cable until the plug is fully inserted into the jack. If it's a speaker connection, that can certainly damage the amp. You absolutely want the amp off before doing anything with the speaker connections.
