Here's a quote from the third interview where Michael talks about his 12-string Gretsch guitar:
Q: The 12-string Gretsch you played on the last Monkees tour was a thing of beauty, terrific-looking and sounding. What instruments are you using on this tour, and how does your gear set-up differ between Monkees shows and solo dates?
A: As I say, in the solo shows I play in front of a wonderful band. Paul Leim and Joe Chemay, drums and bass respectively, and Chris Scruggs on stringed instruments and Boh Cooper on keys. So they do the heavy lifting and make the evening really alive with great performances. I focus on singing and sort of strum along with a Martin J40-12 – which they no longer make – and I send it into the board direct with a mix of a pick-up and an on board microphone. It sounds wonderful and sits in the background of this band in just the right way. I also have a great front of house mixer and monitor mixer that makes the show a real joy to hear and to play. It all sounds fantastic to my ears.
In contrast, the Gretsch is front and center with Peter’s guitar and bass on the Monkees tour. The Monkees have a back up band so that Mick can get out from behind the drums and sing. With the backup band the complex arrangements of the records are maintained. The Gretsch really sings as you noticed – and for the end I switch over to a Strat with Seymour Duncan pickups for “Pleasant Valley Sunday” and “Listen to the Band” – which also closes the Monkees show. Both Gretsch and the Strat go through a Fender Super Sonic Twin –one of the new ones with tubes.
