My ThunderChild 212v1 was reunited with ThunderDaddy Duke about 3 years ago. Turns out the cabinet is the prototype TC212. Duke was unhappy with the way the DuraTex was aging. He requested that I send it back to him for a checkup.
Duke gave it a cosmetic makeover at the ThunderFactory. When it returned to my place, it looked brand spanking, sparkly new, with pristine DuraTex. My roadworn, relic'd baby was reborn. Apparently, Duke changed his DuraTex finish method after this prototype. The update still looks great 3 years later. There was no charge for the makeover, and Duke refused payment.
Duke also gave it an operational checkup, finding everything working as intended. It returned sounding just like it always did, like the most phenomenal cabinet I've heard. It pounds, grinds, and snarls to this day in the amazing way the TC212 does.
Duke's cabinets are among the best. His customer service is the best that I have experienced. His products are well worth the wait. I am so grateful for Duke's ingenuity, design, artistry, craftsmanship, sense of humor, humility, enjoyment in working with bassists, and service commitment.
Prayers, blessings, and mercies for Duke and family in this time of challenge and hardship.
