Well there was a thread much earlier discussing the Lowdown and I can confirm to everyone it's a great amplifier. I have the 12" cone model, it's 150W and it's proving to be very powerful. The sounds is great, with a good low and the highs have a nice punchyness to them. Concerns were that it's quite heavy - I'm sure the other models (the 15" combos) are heavy, but mine is carryable (not that I'd like to trek it long distances) but it'll do. I suppose it is big enough though that I wouldn't consider taking it by myself on a train (unless you're a beefy bloke). The effects are really cool - it took a while to get used to all the different EQ's in combination with the different models and effects but I think I'm beginning to understand them now. I particularly like the Synth effect, since each EQ change entirely morphs the sound of the Synth, meaning that it's extremely versatile. Other plusses? The inbuilt tuner is awesomely useful and the tiltback design will be great when I'm gigging. Also the fact that you can save 4 presets of any combination of sounds is great and with the footswitch it multiplies out to 36. Also, having a compressor will be cool for changing between slap and fingerstyle - the volume at a gig can be different enough that people can't hear you slap as well. Complaints? Well none so far - maybe the weight slightly and the fact that you need to buy a seperate footswitch if you want to change between the different models easily on stage. And also the envelope filter is really, really nice, but I think a foot operated Wah would sound better (since the sound can go underwater unless you turn up the treble and upper-mid considerably). However, if you buy the footswitch, the 'Volume Pedal' acts as a Wah as well. Lastly the 'brit' and 'R+B' models aren't that special, but I haven't really fully played around with them yet. So, any other opinions on them? PS: The Line 6 site explains everything else that the thing does that I haven't bothered to cover .
