On the rear panel you have the standard stuff: a power switch, a power cable connector, a connector for the optional VFS2 dual footswitch (which toggles the reverb and chorus, and lets you switch the All Mute function on and off), DI out (nice!), tuner out, L/R lines in, and an auxiliary in.
On the top panel, things get more exciting. There’s a Master volume, an All Mute switch, and a sweepable Anti-Feedback control for starters. The two channels are laid out very clearly and sensibly. Both have switchable phantom power (sweet!), a Chorus button, and a Gain switch with High and Low settings (High packs a serious punch), as well as Volume, Bass, Middle, Treble, Color, and Reverb knobs. Both channels also have XLR and 1/4" inputs— a real plus for singers/songwriters. One channel also has a 12AU7 tube in the preamp.
Most of us associate Vox amps with a wonderful, chimey, growly tone that some describe as “sugarcoated road grit.” With its 12AU7, the AGA70’s Tube Pre channel gives you tone much like that, only appropriately tailored for an acoustic guitar. It’s more like a “sprinkling of faerie dust against a twilight sky” kind of tone. The key is the Color control: Turned counter-clockwise, it gives you a dark, fat, smoky tone. Turned all the way clockwise, it gives you that sparkling, golden-brown goodness.
