Yes to be fair the basses EQ suite and associated qualities, such as cavity isolation, screening etc is not the best, but all that can be changed. I will as a rule dress and re-fit any bass i use to suit what i want.
The first thing any bass i choose to use is the look, if that fits what i want then the feel, if the bass feels good then i am in business and then everything else can be changed to suit my needs. My bass was stripped down and re-built with ease including the addition of coil taps added.
I use a Retrovibe RV4, first off i wanted a black and white Rickenbacker shape, so that measured up. Then i wanted a lightweight but balanced bass, that measured up, so the bass suited my purpose. Take into the fact the price allows me to customise and add to any value and it was a no brainer to get the bass.
Dealing with Dave, the owner of Probass who designs and distributes Retrovibes was smooth and easy, a great guy to do business with.
In the link is a video of what was done to mine, it regularly draws comments and many who try her will normally over estimate the cost of it (£365 including the custom work) as double the actual cost. http://m.youtube.com/watch?v=bgP2pugAzvo
