Hi all. I´m a happy owner of an AFB. Not too much time with it yet, but so far so good. Great standalone tool for rehearsals and not tonally complex gigs. Also great as a part of a pedalboard, for more complex gigs. Now, I´m considering an A12 because I also need a “presets” rig. In one of my bands, I need lots of tones in the same songs (long instrumental tunes), and sometimes I have to do it in the middle of a solo, so I need to do radical changes with just one click. That´s why I need presets. No other option here. Tap dancing not allowed. Moreover, in this band I also play acoustic guitar, so I want my new unit to be able to manage 2 guitars. Both will be plug in it (input and fx loop return), and presets will handle the effects of each guitar. To get this done, I´ve got a Zoom G5n, which I use with the electric guitar, and a Logidy EPSi, which I use with the acoustic guitar (with acoustic IRs from 3Sigma). Well… Don´t get me wrong… I´m quite happy with my rig. Don´t be fooled by the “cheapness” of the Zoom G5n. It IS fantastic. It sounds really awesome. Amp models are impressive, the cabs are IRs, the thing is really well built, its size and weight is good for a 8-switch+exp unit (better than most of competition unit), effects are also good, the screens let you know the presets before you stomp them, it sounds good from the beginning, quite easy to dial in good sounds, etc. And the EPSi is fantastic too. It´s the fastest IR loader in the market, stereo, small and lightweight. It makes my budget/average acoustic sound like a good one. But, now this band is getting more “pro”. We are now getting big gigs, even out of Spain (our country). So I think I can improve some aspects of my rig. I don´t think the sound could be improved too much. Honestly… Of course the AFB sounds very very good, but the G5n does too, and the difference, in this case, will not be too big because this band need more of processed sounds than “acurate amplifier sounds” than it should be in classic rock, for instance. Even at “amplifier sounds”, I feel happy with its sound. Don´t need much more. Even though, A12 would be an upgrade, in sound and feeling. But this is not the big selling point. Let´s see: One possible upgrade: stomp switches. I need at least 5 presets, and the G5n only manages 4 without needing to scroll banks. I can live with it, but sometimes I make a mistake scrolling and choose a wrong preset. So, if this could be addressed, it would be good. A12 is more than enough at this point… there are lots of switches. Good. Other possible improvement: size and weight. I´m travelling to other countries, and the flights are a nightmare for carrying gear. G5n is reasonably small and light. I mean… is smaller and lighter than, say, Line6 MFX or any other MFX unit (with enough switches) except the A12. Well… another point for the A12. Good. Maybe this is the only reason why I don´t like Helix. I can´t carry it in a cabin suitcase in the flights. Other improvement: the built-in pedal in the G5n has a big fail… which is not being able to handle GLOBAL volume. From patch to patch, the volume resets and that´s a real PITA. This is a must for me, so I am needing to put an extra volume pedal to go on. A12 doesn´t have built-in pedal… for me, that´s good, so I can plug and exp pedal or use a volume pedal. Good. The final improvement: one unit to rule them all (guitars, of course). It would be great to handle both guitars carrying only one device. The A12 has a loop, so you can plug the acoustic to the return, prepare a preset with the acoustic IR and apply effects (comp, reverb, EQ… whatever). Great, isn´t it? Well… yes and NO. There is a wise owner of an A12, and member of this forum (Andy), who has stated several times here that his acoustic presets in the A12 lack the possibility of BLENDING the acoustic IR with the dry signal of his guitar. He thinks this improves greatly the sound of the IR (as it seems to happen with the Fishman Aura system, which sounds much better blending the image IR and the piezo signal at about 50/50). A12 does not have a blending control in the cab block. A simple parameter would be enough, it seems quite easy to add to the Amplifire and editor. So, to get this really good, Atomic should be adding this. Helix has this feature. This is one of my FEARS (more than that, it´s an important detail that probably will keep me from buying the unit), since I´m planning to check what Andy says about blending and getting better acoustic sound (still can´t do it because my acoustic is being setup by my luthier). This FEAR becomes slightly reinforced because of the fact that Atomic seems not to be updating firmwares… more than a year, isn´t it? Atomic guys, if you are reading, please, review the wishlist and give us a little attention. I think we are happy with your boxes, but really isn´t that hard to make us even happier. And I absolutely believe that you´ll sell more units if people see you releasing updates frequently. Other things could be desired from the unit… a global graphic EQ (with 10 bands, for instance) which could be activated/deactivated with a stomp (very useful to implement Fletcher Munson curves, so you can dial in your sound at home volume and then, go to the gig/rehearsal and, with a simple stomp click, compensate the high volume differences in human hearing sensibility… so your tone don´t inexpectedly suck). Helix allows you to do that. Another example, what people say about bad reverb of Amplifire (honestly, in the AFB the reverb is not bad to my taste, but I´m less than an expert in that matter). I think Helix is much more complete, and they are in the same price range. So I also think A12 is a bit pricey in comparison. And we still don´t know if Atomic is letting its product fade away, and that´s a REAL FEAR for me. We all would love to see this people more active in the updates, wouldn´t we? Please, don´t hate me for this huge post… Cheers!
