I'm really looking forward to trying one of the WD-800's.
I've always wanted to own a Mesa amplifier. When I was learning to play the guitar in my 20's the Mesa Rectifiers were hugely popular with the alternative and hard rock bands I was listening to at the time, so obviously I wanted one. Then as I matured and started to listen to more blues/rock Mesa released the Recto-verb 25 which became my dream amp.
Now I'm an aspiring bass player I'm keen to try some of the Mesa Bass Amps and I'm really bought into the whole Hybrid thing.
I part satisfied my Mesa itch last year by picking up the Subway Pre-amp, but the WD-800 looks great for what I want out of a head.
I'm looking forward to seeing some demo's and hearing some user reviews, I'm sure a few BCers will pick them up pretty quickly.
