Although I'll qualify that by saying 'for recording' at the moment. Took the plunge last week. I'm a committed valve/ tube amp player, but for home recording it isn't really practical to mic up two amps ( in stereo), so for the last few years, I've used a Tech 21 Liverpool pedal as my 'amp'. It sounds great in a mix for clean tones, but struggles a bit as I add gain, particularly with single note stuff. This is what pushed me towards the AFB. Other than some of the earlier Line 6 stuff, I don't have any experience with amp modellers. The fully featured units really do not interest me at all. I get bored/ impatient with too many options, so the AFB sounded exactly the kind of unit I needed. I have to say straight out the box, flicking through the presets I was quite underwhelmed. I started to adjust the knobs and was beginning to believe I'd made an error of choice. It didn't sound terrible, just not as good as I was expecting. But then, I tried some of the suggested settings. Then, I found the preset section of the Atomic Forum ( via TGP). And only then did it start to make sense. Of course my disappointing experience had mainly been due to operator error. I'd been starting with the gain and tone controls broadly as I would with my amps and not finding the sweet spots of each model. Doh! The 65 Deluxe and Top Boost models are magnificent for cleans. Still trying to find my ideal dirty amps, but really enjoying the Plexi and 800 so far. I think it'll be a while before I was brave enough to use it live, but at the very least I have an emergency back up now.
