I've got one of these on order, should be a month or two away. In the meantime, I've created my own Tone Blender by combining an X-40 with my Fralin amp. The X-40 is connected to the top speaker (Eminence Red White & Blues) and the Fralin amp is connected to the bottom speaker (Tone King 1891 hemp cone) in the vertical 2x12. The guitar runs into a wah which runs into an ABY box set for Y mode, channel A from the ABY box goes to chorus and delay pedals and then to the clean Fralin amp, channel B from the ABY box goes right into the X-40 which has footswitches for the clean/OD channel and a global boost. Holy Sh*t Batman, this sounds orgasmically great! The Fralin amp with mid-scoopy speaker provides the base clean tone with deep lows and extended highs, the X-40 with darker speaker provides all the midrange punch and gain textures. Having the two speakers in the same cab really helps blend the sounds from the two amps. Two thumbs (and ten toes) up!!!!!!
