I had a number of the DeArmond T400's and found them to be very nice guitars. Interestingly I eventually picked up one of Crimson red early model T400 and it had a number of issue with the neck. I returned it. I did have a Blond and TOrange one also. Both great guitars. I sold them after picking up a Red mahogany DE400. In hind sight I wish I kept the T400. The T400 was considered DeArmonds top of the line guitar. Where the typical DeA neck had a "scarf" joint Bonded Headstock the T400 had a Head with "ears"" on the neck like a standard Guild guitar.
Had I kept them I would have swapped pickups and added Franz and a set of 2000's. Those DeA T400 don't show up very often. During the DeA blowout days they were selling in the $300 to $400 range, no case.
