Chet Atkins

Vintage Guitar's June, 1996
interviewer:Dave Kyle
Chet: "On the road, I use a Music Man 112 RD. It�s 50 watts with a 12-inch speaker. You know, I�d like to take an amp with two twelves, or a 15-inch, but they�re so heavy..
So (Les?)Paul and I both use the Music Man. They�re not manufactured any more, but they�re around, you can find them. I�ll tell you, I just accidently discovered that nylon string guitar sounds better through that amp than any amp I�ve ever used. So I started using it, then Paul started using it and a lot of people buy them now and use them. I had a larger, 100-watt Music Man. Paul�s got it now, but it�s so heavy. It doesn�t sound as good to me as the 50-watt."
There you go. Quite an endorsement!

gee, I thought that would have provoked a bit of a reaction!

it did man trust me!
we are speechless

The "Paul" that Chet was refering to in the Vintage Guitar Magazine is "Paul Yandell". Paul Yandell was Chet's sideman for about the last 25 years of Chet's career. They both used the Music Man 112 RD fifty on the road for about the last 10 years of Chet's career.

Here's a photo of Chet with a RD50 in the background:

I actually wrote and email to Paul Yandell, and he responded...seems like a really nice guy too. He stated that Chet always recorded with his Standel amp that he'd used forever. However, on the road, it was always the Music Man RD112-50. He said they were built like a tank and extremely reliable.
