Yes, back in the early 70s I had a BV for awhile that had been chopped, and percussion added, by Ed Harrington here in Chicago. Ed was selling them to rockers all over the Midwest. It never gave me a minute's trouble even though it was going in and out of a truck on an almost-nightly basis.
I subsequently got out of rock n roll and sold it to a keyboard player who took it to Los Angeles, where Bill Beers at Keyboard Products did a "re-chop." My guy subsequently then toured with it for a number of years before eventually selling it to a gospel-playing church organist in LA, who I am told is still using it to this day.
Some machines refuse to die, even with over 50 years of pro use, if well cared for by technicians who know what they're doing.
