I never expect a bass to have a perfect set-up out of the box, regardless of value.
The only time I would expect that is purchased directly from a luthier.
I'm looking at getting a TC MojoMojo (anyone selling?) and would like to get an idea of how big the gain jump is from the Spark Booster to the Mojo.
TLDR: How much more gain does the Mojo have over the Spark Booster?
