I took the 18″ cab apart for the first time in years to inspect the wiring and vacuum it out. The Black Widow (Model 1801-8) is in great shape. It’s over 10 years old and the cone seems to be holding up well. I took the opportunity to aurally inspect the output of my MB-1 preamp, and it’s clean. Connecting that to a Carvin F150 amp confirmed that the 18″ cab sounds fine. That leaves my venerable ADA B500B power amp that’s introducing distortion. I’ve never even looked cross-eyed at it; I’ll be checking out its insides for the first time. At the very least, it can probably use a cleaning. The F150 will be an OK power amp in the meantime; I’m not playing out with the rig… yet. 😉
