Boss VF-1 Effect Processor

Hi,

I've had my vf-1 second hand 3 years ago. I'm using it
on my live performances every week.

During the performance, after 1 hour, the output sound
of vf-1 goes down, to a very low level. Actually it
show that the output level (volume etc) is all up, but
the output sound is so low.When I close and open it up
after waiting for 2-3 min., the sound comes to normal
level. After 30 min. it goes down again.

Is there anybody there had this problem before. I
thought it was about vf-1 gets heated. Or any ideas?

I use amp simulators, reverb, sometimes NS and EQ,
that's it. My global setting is set to "line".

I use FCB1010 footcontroller with the VF-1.

And, I should mention one thing too, In my country our
city voltage is 230V, but vf-1's AC power adapter is
110V. So, I use a converter with the AC adapter.

Any ideas and solutions?

Best Regards...

Cagan
