This is the old adapter. Carl Martin PowerJack I think. Never made any problems (sibeh quiet) until..
The dents? It's like it melted inside, no?
Whatever it is, i got a new adapter. Not sure if I made the right choice.
But when I hook it up with daisy chains and all, it became very noisy, white noise. There even was this high pitch whistle sound coming out.
So I started my investigation. Tried out each single pedal and patch cable. sadly I only have the one set of daisy chain and adapter but I found these.
A) My favourite pedal, the pedaltank G2 distortion caused the whistle sound, variable on its gain knob.
Desperate, I opened it up (I don't usually do. Scared. But now, desperate.).
G, L and T are the control on the other side.
I = input and so on..
Findings:
-With or W/o daisy chain, same.
-Batt or adapter, same.
-Noise louder when i add an OD to the chain.
-Even worse when i add my Digitech digital delay. Got weird noise like spoilt high pitched clockwork.*
-Red light seems to be like a signal sensor. Got signal, light up.
-Touch (with finger) on A, the whistle change to abit lower pitch.
-Tap C, and there'll be tapping sound coming out from amp.
-Touch B, the whistle stops!! and the light comes out, pedal operates as usual.
So the pedal IS spoilt right? What could have caused it?

"* Increased hum or noise can come from trying to power dist/overdrive pedals together with power-hungry pedals like digital delays, chorus pedals etc. If you get noise, try separating them and powering them from two separate adapters.
My DD eats 300mA. BUT everything worked fine on my old adapter.
B) My DD causes white noise in the chain. Works fine on the old adapter.
C) My Fab Chorus, same thing.
SOO..
if the adapter, like i assume melted caused by short circuit(?), could it have affected the whole chain.
