Guitar preamp lights (but there must be a diode clipping somewhere)
4 MIDI channels
19 "1U
2 ECC83 for the clean and OD channel
Assignable effects loop on each preset

To see the rest of the Marshall site ...

8 / 10 there could be the same as the Schma SERIES 9000 (3 lights) to do well and mature APRS rflexion a guitar between the rear of the s'avre indispensable instrument (too galre cables in a rack when you have a unit for the effects pregain).

UTILIZATION

The use is very simple you press the buttons, turn the data wheel and we do store 2X!
The EQ is effective trs which allows the hair well rgler presets.
The sound is not immediately the need to rglages 50000 ...
The manual is short but it is not useful, but the factory presets contain really cool stuff.
MIDI makes it versatile and flexible trs.
The stereo effects loop is assignable to each preset and assayable thanks to the Effect knob is simply a dry / wet (0 is no effect, 6 were 50/50 and 12 was 100% the effects )

SOUNDS

I use it in a Hard US / Rock FM and it's perfect!
It has the sound Marshall (personal I mount with a 12AX7 in the VHT clean and EH 12AX7 DO) and it is rock trs.
Clean 1: fairly warm with lots of low mids
Clean2: more bright and prcis, EQ more hollow (nickel to attack modulation effects, for example)
OD1: too much gain (rock / hard) with a lot of mdiums and body
OD2: more gain and also prcis
Trs is versatile while keeping his personality the Clean 1 and 2 are nickel (even if it is far from a Twin or Rivera!) And Satus are in line with the brand (JCM800 / 900 or Plexi hotrodded ...). In addition it perfectly boosts cash or OD upstream.
The sound is still quite rock and not dborde no gain, has not the precision of a VHT or ENGL, Marshall is a what, I love to love me!
With good lighting Higain (Ei, Tung-Sol, Golden Dragon ...) you can even explore the terrain of the big mtalleux (Deftones, Fear Factory ...)!
To quibble I would say that crunches are not up to the mark (JTM, Plexi, JCM800 ...)

8 / 10 because it sounds very serious except for a little crunch and steep that, despite its versatility in terms of use when you stay in the same typs sounds very own brand English and who are all somewhat resembling (which for me is far from being a default, but to love).

OVERALL OPINION

I've had 2 / 3 years and only a Soldano SP77 could make me feel like her!
On OCCAZ 'it puts the 300 to pick up many of its competitors and sometimes even the most expensive (given that it is more reliable hyper)!
I hsiter remake that choice without a single second!
If you like the sound Marshall pramp this is for you ..

I put 9 / 10 because perfection is not of this world and that has shit to have no input jack the rear!
