I've been playing my ThunderBolt 4 for 25 years now. Great bass. Very ergonomic. It has a fairly polite Bartolini soapbar sound in normal mode but can get more aggressive when the Thunderguts switch is engaged. One caveat, though: the Thunderguts circuit significantly boosts output, possibly overdriving whatever comes next in the signal chain.
It truly is a special instrument. It feels just right on a strap, and I get compliments on its sound frequently. It sits in a mix without needing much fiddling.
The one big thing to check when looking at one is if the truss rod turns smoothly. Mine has frozen up, and it's a not-uncommon problem with Pedullas. It's fixable, but I'm leaving it alone because it's set up perfectly for Hi-Beams, and those strings are ideal on this bass.
You can see where thousands of hours of playing have worn a groove in the top. That bass is mine forever.
In short, Yes, you definitely should if the truss rod functions.
