Thanks Darren!,I also love the fours,As for the sound,The 1998 Morado bass has 9volt elec. and the Black Tiger has the 18volt.The Black Tiger has the dip switch that let`s you set the tone you like,I myself like a lot of bottom because of the Blues that I play!.Both of the basses have a wonderful sound,As for balance they are perfect,The flush mount strap locks really don`t make any difference that I see,They both are great with balance and weight.Have been playing Ken`s basses for a long time now,Been thru many different basses over the years and and found my home with Smith Basses hands down the best on the market!!!!
