r16ktx Posted November 24, 2015 Share Posted November 24, 2015 (edited) I am selling this classic 80's ADA MB-1 Bass preamp. It has been retubed with Mesa Boogie Tube SPAX 12AX7 [url="http://mesaboogie.com/tubes/pre-amp-tubes/SPAX7.html"]http://mesaboogie.co...ubes/SPAX7.html[/url] Has some rack rash, but no dents or wear due to negligence. The power cable has been made shorter (to 45cm) so as not to clutter the rack. Everything works fine and sounds great and is extremely powerful unit for shaping bass tone.
