Boss VF-1 Effect Processor

Hi All

   This question is open to all who read it.

   I'm currently looking for a rack effects unit to finish out my 
system. I have just returned a Boss GT-6B floor effects unit and 
although it pained me to return it I had a more difficult time with 
having to lean over all the time to make adjustments to the effects/ 
parameters. I would prefer to have a rack mount unit to work with.
    I'm avoiding the Line 6 Bass pod pro for several reasons the 
first of which its primary function seems to be a cab simulator/DI 
recording unit and not an effects unit. It does have a few effects 
but nothing compared to a GT-6B.
    I cannot find out anywhere that states what effects are actually 
in the VF-1 unit or if it has a guitar pre amp in it.
    If anyone has any suggetions on what could be comparable I would 
really appreciate it. One note that I dont know if its true or not 
but I was told to avoid effects units that have a guitar pre amp in 
it and that it would sound like crap for a bass...Any takers.
