Excellent amp, I just bought a new one recently. Also have owned a metroplex.
George has not stopped making them, but he did say recently that he has just used his last head shell and won’t run any more for a while.
It’s super versatile to me and what I play. 65/66 mode are really where it’s at for me, the 68/mod are a bit darker and just not what I usually gravitate to (but nice to have). The boost is excellent and very tweakable, and the mid boost is just perfect for solos. I love it.
