Transistor 100 watts
4 effects
4 channels
Basic settings + general volume

UTILIZATION

Very simple amp, the sounds are convincing, very different for the three main channels (the lead is a more powerful clone of the warp). Nice selection of pedals, but I dropped twice (the first, it was still under warranty, not the second ...).
With the effects, settings are automatically saved for each channel, it makes life easier. I bought the pedal that can trigger effects and reverb.

SOUNDS

I play rock (ranging from pop to metal type Metallica or Dream Theater) and Yamaha RGX TT and Ibanez RG.
The sounds are good.
The clean is really interesting, warm for a transistor amp. The crunch is my point of view a little rough (probably the side transistor), but nice if one looks for a slight popping sound.
The warp is excellent, personally I do not dose the gain to more than 2 / 3 and it gives. I had a blast on this channel (resistance has blown?) Which unfortunately is embarrassing.
Lead is a real plus when you play in a group where there is a keyboard and a second guitarist, although a boost would have "leader" for each channel.
Downside: the modulations tend to warp easily be invasive.

OVERALL OPINION

I've had 3 ½ years.
It's a nice amp, but could be improved. I do not use much anymore, because I completely changed everything for the Line 6 Flextone III XL (what a name!).
I do not use more than only in its repetition and clear with multi-effects (problem with the pedal tuner).
I enjoyed, for the price, 4 channels, onboard effects and power.
I will not repeat this choice today (other amps have come out since).
