One reason Louis has the best rental B-3's & Leslie speakers in the NW is that, being an organ player himself, he knows when something's not quite right with his gear. The other reason is that when he can't fix a repair issue himself, he takes his B-3's & Leslies to Steve Doherty at Keyboard Engineering.
