There is a local pickup listing on Reverb for a 90s vintage Blues Jr for $325. It's the next town over from me. The listing claims it was professionally serviced and it comes with a 90-day warranty. Two questions: 1: Is that a fair price? Condition appears "Good". Some of the text is worn off on the control panel. 2: Anything to look for if I'm able to test it out, besides it sounding good? Anyone familiar with these units and know of any quirks - always has a little hum, power switch always makes a pop, etc? Any input is appreciated - thanks!
