For those who are wondering what these small amps are like. They do NOT sound like a Marshall 2204, but the the circuit is very similar. Hi-Lo inputs 3 12ax7's and 2 el34's, 4, 8, 16 ohm jacks on mine and a line out jack that sounds ****. Controls are: Presence, Bass, Middle, Treble, Master and Preamp. The preamp is very very hot. Too hot actually which makes the sound a bit mushy through the high input and makes the amp sound out of control at times. When the pre is dimed it sounds like a big muff fuzz. Whats nice though is that it was an easy fix to lower the gain some, I changed the value of the cathode resistor on v1.2 and the distortion is now more defined and the overall feeling is more "stable". The amp is really pretty easy to work on. This, like all tube amps sounds best when the master is turned up to between 12 and 3 o clock. Very nice distortion sound with alot of detail. Sounds fuller than a marshall, a bit fuzzier if that makes sense? But at the same time it has a dryer response with not as much sag. More like a Hiwatt in that way. I love this amp for distortion sounds and used it in my hc/punk band as well as more slow heavy metal/stoner doom stuff. Its perfect for that, it "holds up" but for anything fast and with low tuning it would sound too muddy. The clean sound is not that bad either, very soft, warm sound. Reliability? As good as any tube amp except for maybe Hiwatts and Traynors I would say. Have had a couple of tubes gone bad but thats normal, they can go any time and a failure says more about the quallity of that single tube than anything else. I love this little amp and the fact that the cabinet is smaller than standard size is very nice when you are in a touring band. This and my home built 2x12 cabinet together with my p90 Edwards LP special is all I need for basic heavy rocknroll.
