If I could give this thing zero stars I would, but you have to give one star in order to post a review…so with that out of the way…where do I start with how useless this thing is…how about, some background. I’ve been playing guitar and have been in and out of bands and recording studios for the past forty years…So with that said…First, l’ll start this review by pointing out how overwhelmingly muddy and bass heavy the amp itself is, and that’s with plugging the bass port. Additionally, trying to use the bass controls (in the apps amps) to tame the bass is useless as well. Also, the treble controls either add harshness to the tone, or are useless. Plus, I tried a Strat, a Tele, a Les Paul, an ES335, a Firebird, an Explorer, a Gretch, and a Yamaha, and didn’t make a bit of difference in getting a passable tone. I also tried single coils, humbuckers, mini humbuckers, P90s, and soapbar pickups, and that didn’t help in dialing in a satisfactory tone. And trying to get a tone on the amp using the bridge, neck, or the two together was futile. Though, I will say this, if you play metal the this app amp and app are passable. Look, I could go on, but I won’t, though I will offer this piece of advice…do yourself a favor and buy a Vox Valvetronix modeling amp, or a Yamaha THR series, or just buy Bias Amp 2, or Bias FX 2 and an iLoud, you’ll be better off. The only thing the this app amp is good for is a door stop. Again, avoid this thing like the plague!
