This is an Ibanez 2451 BK, the black version of the 2451 NT. She’s basically an L-6 replica. You rarely see the original black version of this guitar, especially in this condition.
The 2451 has a special meaning to me, since this was the first Ibanez model I ever owned (blonde version, way back in the 1990s). Unaware of Ibanez catalogs and forums such as ICW, it took me 20 years to find out what model she was and to replace her. So when I spotted the original black version of this guitar, I just had to have it. And I’m glad I did – the 6-way rotary switch gives this guitar such versatile and great sounds!
