Hi all! Just got a great deal on a Diezel VH4 and cab and had to take my only chance to own this dream gear! Got my Carvin back from the shop with a Black Hawk 7 now installed in the bridge, and here is my first play on the amp, just messing around with some riffs from my band. It's through an SM57 and is an accurate representation of what I'm hearing, can't wait to dial it in and get playing with the band on it! \m/ Wow! I didn't even analyse how it sounded, I just kept playing. Amazing, amazing amp, and I haven't scratched the surface yet.
I used the Einstein almost exclusively for our new record (out January 2016). One thing I would note is that even though we play extreme metal, a rear-loaded cab seemed to sound a little bit better for a studio application, whereas the front-loaded is more effective live. Cheers.
