- Head amp lamps (EL 34) 100 watts - 4 Channel

- Difficult to make a comprehensive list of connectivity, the possibilities are Whereas. The head is MIDI (128 presets). We can Intrag on the functions activated by push-pull, but not on the levels of potentiomtres remaining fixed. Ct "plus" was the tester impdance cables and speaker cabinet but also a bias Intgr meter in the camera to change its power tubes and even do their own bias. The icing on the cake is the Systm electronic protection: it being protected by putting the amp automatic stand-by at various potential case for the device (such as when no speaker is connected to the outputs ). If a power tube Submitted overload or a problem, this problem is indicated by a flashing of the LED squence "write / copy" Determines how to light is key .. . This allows self-diagnosis in some cases to know o is the problem and therefore possibly to orient Repair Tool, or know that there is an overhead lamp and cut the IMMEDIATE t te, cel happened sometimes in two years (in almost majority of cases the ignition of standby) and once back on the stand-off and then all back to normal silent

- There are a lot of push-pull correctors gain (gain boost - hi gain), voicing (modern or classic), the Tone (bright, ultra bright, mid edge, contour active mga lo punch, depth boost , reverb) or channel selector (clean, crunch, lead 1 or lead 2). Knowing that they can be active for most simultanment and have a more or less subtle about his, I leave you counting the possible variations ... These functions push-pull can be registered on a pRSET IMMEDIATE MIDI support for three seconds on the "write / copy" of the device. The CONTRL MIDI device ncessite a pdalier.

- Regarding potentiomtres can not be fixed by piling MIDI was the bass middle and treble rglages walking on the principle of sharing qualisation in groups of two channels, let me explain: there is a potentiometer common to middle and bass clean and crunch channels, for there is a potentiometer against clean treble and treble potentiometer crunch. The same system is used to lead the group 1 and 2. Otherwise facade was in 4 volumes of the four channels spars prampli post or two master volumes A and B of the power amp). For the rest of the potentiometer intensity of rverbe etc etc ...

- Ct Aesthetics this amp is exemplary (specially mention the lighting of lamps by LEDs rtroclairantes)

UTILIZATION

- The avalanche of rglages is possible to dpart Drout, you really spend time on bte to tame. The big rule of thumb in the RSID fundamental diffrence between the two groups of channels (Clean / Crunch and Lead I / II Lead, but may be that I came across a device dfectueux ...) : Lead channel / crunch sounds pretty offers thick and it took me a little curb. The Lead channel I or Lead II will be almost unusable (sound far too late) if you do not use any function to boost the sound as the depth or boost mga lo punch. This is why one can find that this head not sound when the top is trying for the first time, because logic dictates that we put the qualos around 24:00 without turning on any corrective function .

- Apart from these few problems, the head is ultra simple to use: I drive the pRSET of my head and my multi-effects with the Z-12 pdalier

- The manual is well done.

- Use MIDI is intuitive

SOUNDS

- The amp is versatile, especially with its six channels:
1) clean channel will distort the average allgrement mode lo gain, and distortion in prcise supported and hi gain
2) channel that gives good crunch distortion in the nerve fawn or AC-DC&#39;s Gun N&#39;Roses in lo gain, and more (mtal) with a hi gain in warm ct
3) a lead channel: its ultra ultra prcis (too may be). Whereas a reserve of gain (I do not push the knob at 12:00 in del hi gain if I "over-saturated"). As against this channel sounds a bit late with small rods and strings in standard tuning, I guess he is made the basis for seven strings and detuning.
4) lead channel 2: compared to a lead, the lead 2 is low in fat and less dry (one made more liquid because Designed for solos). It can sometimes get a little "muddy" due to low overhead and if you have a heavy hand with the gain knob

and bonus:

5) driver tube channel: a channel that puts her a 100% pure without alteration directly into the Poweramp, gives his vritablement standard amplitude.
6) TDHQ: the same channel as above but offers rglages supplmentaires of sensitivity (its light crunch of good quality and EQ rglages bass, middle and treble.

Once the basic grain found there must also choose among the options proposed:
- Bright and ultra bright: give shine and make the sounds more Arians
- Modern or classic: Intgr a compressor with a compression ratio equilibrated to let the attack. the effects of modern fashion are most apparent in lead 1 and 2, as also an active cell qualiseur semi paramtrique (scoop the mids and bass boost).
- "Gain boost" - "hi gain" boost the gain
- Mga lo punch: boosts the low level prampli
- Depht boost: xagrment boosts the low level of power amp and the sound really fills
- The noise gate (which I find good trs)
- The rverbe (2 knobs of rglages indpendants: 1 for clean / crunch and one for a 2 leads)
- Mid edge: boost paramtrique in mdiums with the least rch, consquence grows in a little sound, I use it for all my pRSET
- Contour Active: boost paramtrique a range mdiums
- Selector masters and prsences (A or B)
- Mode 50 watts 100 watts
- Select effects loops (2 and 1 in parallle SERIES)
- Selection of A1/A2 and B1/B2 HP outputs: to go "on the fly" during a change of a patch or two speakers on the VHT or the output (s) for large mtal, one or two speakers on the fender or output (s) B for clean sounds

So ultimately the ability trs strained thor, but Ralite activation options unfortunately can change the sound levels or the amplitude of the signal. APRS will not pose problem that people like me who want to use 5 channels Manir homogne (TDHQ, clean, crunch, lead 1, lead 2), requires a little juggling for a cohrent all.

I think this amp is extremely dynamic and right (or steep) in the sound, and it lacks consquence heat compared to the marshall or boogie msa (and even have APRS chang lamps prampli MODELS for the warmer sound) ... It feels REALLY clear orientation towards the mtal plutt and drive that to the blues rock ... It&#39;s the only complaint that I do on this head

OVERALL OPINION

- This amp is versatile in design trs: you can switch from one channel trs clear a monstrous distortion, then board a rock crunch rhythm in the crowd in the blink of an eye. The sound always keeps his label and we can ENGL give him a lot of tonal variations in order to get as prs sound that was at the top.

- The amp is Designed originally to be self-sufficient in basic functions and thus dispense with a multi-effects ... A real Swiss Army knife

- The price may seem trs lev but if you look at the finish and the possibility of the device (just take a oail diagrams of front and rear) is justified. Investment but a hell of a value sre.

- I have since 2006, I go out in systmatiquement rptitions and I have not had a single fault with, no fuses or lamps grills, nothing, nada ... For me it&#39;s a great sign of quality especially for a product if sophistiqubr />
- The single point ngatif I find this head is the small lack of warmth in the sounds it dlivre (as I mentioned above can be that I came across SERIES bad who knows) ...
