Question bout MarkBass TTE500

[wishbon7]

I've been putting this off cause I thought it was a dumb question but curiosity has finally gotten to me. When u look though the top at the inside of the this head there r some light yellow LEDs and one red LEDs . Is that right does everyone have that one red LED. Or is something wrong with mine. Are they all suppose to be yellow?

It's ok.

Mine has the red LED too

Cool thanks man

The TTE-800 has one red LED too.

I believe the red LED indicates that there is still power in the amp. Don't start changing valves or playing around with the head until it has faded completely.
