UTILIZATION

The configuration it is relatively simple even though it is a mesa boogie, and therefore
the equalization is trs trs fine. Once the equalization is open your ears because we can say is the best lead sound a guitar can dream on this earth.
Very rich in harmonics, its very specific series of linverse rectify that tend to drool over. To imagine the sound of Santana Europa think this is typically the raw sound that you get with the Mark IV's lead. After other virtuosos such as John Petrucci, among other uses since the early 90 and still considers his favorite amp.

-The manual is in English it is quite clear Ormis few details but it's probably my English is not great

SOUNDS

I touch a little bit every style according to lhumeur so I chose the Mark IV for its reputation of the most versatile amp in the world and I can now confirm after 2 weeks of use, clean lens and very very hot deep crunch fall down a bit in the style JCM 800, and lead very gorg right harmonics.
The amp has a lot of gain (metallica, lamp of god, dream theater) use among others) but has not the weight of a grinding head can not have it all.

I play this amp on a Framus 2x12 with celestion V30LE vrement result is very good
and I played on an OLP Petrucci signature with dimarzios, it fulfills the task
for the progressive metal style that I like

OVERALL OPINION

-2 Weeks of intensive use
-I die for his classification as "orgasm"
Price-quality ratio is hard to judge, but if there is a price for the enjoyment sound and well in this case it is worth the price it cost: 2800 euros and nine around 1750 Used

- With the exprience, you do again this choice? ...
OBVIOUSLY
