It's the Merle Haggard custom shop signature model.

I played a set neck Tele in Hawaii and wasn't all that impressed but a lot of that was due to the setup and lack of interest shown by the shop owner who wanted to sell me a $4K uke rather than a $700 Tele ( the only two electrics in the shop were the Tele and a Shobud Maverick pedal steel plus a Princeton & small Vox amp, played through the Vox )

I don't feel that the set neck added anything to the sound or made that much difference to the upper frets and I don't often get above the 15th fret anyway
