if its worth it to me at this time... probably not since I am fortunate enough to have another fretted with this option....

Yes, the 18v drains 2 batteries but it has twice as many volts as well. When the batteries are down to 4 volts each, you still have 8 volts there. In essence, you have twice the battery life as the 18v model drains the same power as the 9v model, about .03 milliamps the last time we checked which was back in the early 1980's.
You are right about the 'output' power, no difference. The same as in a car. Two car batteries under the hood in series will not make the engine run any faster. It will just take longer for the power to go dead when you leave a light on.. lol
The other two differences with the newer 18v unit are the construction/durability and the internal D.I.P. Switches.
We have replaced quite a few 9v circuits from breakage between the Pot legs and the 'boards. This happens when the Bass is dropped in shipping or banged into severely. Also, when 'futzing' around inside the cavity changing the battery or tightening the Jack, a clumsy hand has broken just as many as the hits or falls. The new 18v model has a steel bracket mount system. You will crack the wood of the Bass before you break a Pot!
The internal D.I.P. switches is the only real 'sonic' difference between the 9v and 18v models. On the 18v model you can have the same 'start' settings (for the cut/boost) as the older 9v, the newer 'Ken-picked' settings as the current 'default' or, any other mixture that you can tangle up on your own. Each of the three +/- Pots (bs/mid/tr) has 4 positions of tone to choose from. Trust me when I say this. "I have tested them all and the two groups of setting I like most are the new and old defaults". After awhile while messing with the DIPs, you will start to forget what sounds good so, just be careful when playing in there as the DIP switch can be broken as well. You need a small tool to move them up and down and this tool what ever you choose can damage the circuit if you slit and hit something in there. I can see a gut playing in a Rock band with a bunch of 15s in the cabinet wanting the treble freq. lowered from 6k (now) to maybe 2k center so he can at least hear it as without a Horn and a good one, you can't hear the 6k boost or cut in the new 18v default or even the 3.5-4k in the older 9v default. The same goes for the Bass and Mids. I have no clue what will sound good to your ears so the best feature of the new 18v circuit is the diversity the DIPs give you to 'tune' you own freq. centers for the +/-.
