bass lessons help?

ok so i just got a bass & i want lessons on it
but i take guitar lessons already
i take them every once a week
my dad wont be able to pay for bass lessons & guitar lessons both each week
so if i want bass lessons i have to take them every other week
& the other weeks i would take guitar lessons
do u think this is good?
will i gte better at both?
ive been playin guitar for a year & 4 months
just started playin bass
so will i still be good at both if i do that?
wut do u suggest?

heres a cool 2-string bass that Bass Player Magazine raves about in the January 2008 issue
