Prampli German-made, super quality of manufacture
4 lamps, 2 per channel (the second boosts Premire, clean / crunch and Lead / Super Lead)
Between an instrument, an output amplifier and an output for recording the simulation knob rglant HP's softer than slamming.
No effects loop, with a TC G-System, it does not need it.
This may be a default, but that would not Depardieu's nose, Kirk Douglas Faucette without her?

UTILIZATION

Super easy to use, we get immediately SOUND!
No manual can be found on the internet Schematic for switch connections 4 channels (clean, crunch, overdrive, hot overdrive). No problem configuration switches with the G-System and pedals Peavey 2 switches did the trick

SOUNDS

As you can see, I am delighted by this pramp I bought 210 euros (hard to find)
Harmonics in harmony ...
I had a Triaxis a JMP1, an ADA MP1, a lag Spitfire, and other hybrid style POD 2, GT8, TRIAC Tech21 (TRIAC trs well), but the I m'clate! ! This prampli sings, he rpond my requests, a standard heat, I prfre the Triax.
For those who do not need 128 but only 4 preset sounds of hell, I suggest you browse the Internet up to find the pearl!
Knopfler of Van Halen, the fearless prampli
In a word, EXCELLENT!
