Hi,

How long of a battery life should I expect on a series 2 if I elect not to use the power supply?

20-30 hours tops. Long battery life is not part of the design of the Series I or II instruments.

I was getting about half that on my Series 1. When they first start to go bad, the top end gets distorted. Much like the sound of a blown tweeter. When I heard that first tell tale sign I knew I had to switch batteries real soon.

I was'nt using the power supply with my old '81 Series 1 and never kept up with the actual usage on the batteries. Sooooo, during a gig they went south and my whole rig sounded like it was blown to hades-all 8 speakers! I use my power supply now and forever.

there's a big difference using the power supply over batteries IMO.
the power supply provides constant proper voltage. Batteries are dying as soon as you use them, may not be apparent at first, but after about 10 hours of use I can hear a difference. The batteries start distorting the sound very subtle at first, then more and more until they're dead. For my series instrument it's power supply first, batteries as backup only.

I have a MK signature, I only change the battery when the sound does the fuzz thing, there is no PS for these models, I suppose you could develop one with a regulated transformer and tie wrapped lead around your guitar cable.
But then again the battery does tend to last a very long time(up to a year or depending on how many gigs you do)

I was using my '78 6 string Series I Alembic guitar the other day with an old tube amp I was checking out (after I had acquired the amp.) I heard a high whistling sound and then POOF....nothing. I thought the amp was blown.

No t the prob: merely the battery giving up the ghost.....When it goes it's all gone.

Have to agree with Michael on this one!!
If you get 10 hours.....you're doing really great
