I am lousy with the soldering iron, so this unit saves me a lot of trouble. It is easy to get everything connected and grounded for a buzz-free tone. The pots have a nice roll-off, feels natural. I wish they'd make them in a version with 500 Kohm pots too for use with higher output pickups like the DiMarzio Relentless. For ordinary Jazz Basses they are top notch.
