Unboxed and fired up my new head today - prior one had non-functional Graphic, FX Loop and Reverb in Ch2 only.
GC was very cool with the exchange, my new head was unopened NIB - as I wanted (as it should be with a $2,000 amplifier).
I'm amazed - I already knew it was an exceptional amp, but now hearing Ch2 with reverb, delay and EQ has made my day/week/month...
I'm running fairly high (6/10) reverb, a subtle delay in the loop, and the classic V in the EQ, and I swear, I'm getting tones in Ch2 that sound as "Marshally" as my actual Marshall head!
I'm a longtime Marshall (2553 Jubilee, JMP1/9100) and Boogie player (Triaxis, Studio Pre, 20/20), I can honestly say the MkV is the best sounding amplifier I've ever owned.
The rack gear is now gone, and I'll keep the Jubilee forever, but I'll play the MkV!
