I've had a bit of a play, after updating the firmware and PC and Android software to the latest.
Nice solid piece of kit. One conventional pot as master volume, one rotary transducer to set parameter values, with a click to select. There are two Bluetooth channels, one full Bluetooth and the other Bluetooth BLE, one for control and the other for audio interface.
Limited effects - there's a chain of up to six, which, just like the old days, are one of each type. However, they can be reordered if required
1) FX
Noise gate
Boost
Compressor
AI Gate MS - I have no idea what this is, it's a recent addition that's not in the manual
2) AMP
1-15 for guitar
16-20 for bass (the models are AgDb750, ApSVT, PJBuddy, DgXu, MarkLm - four of them seem obvious, I assume the Dg one is DarkGlass but not sure what Xu signifies)
Same controls for all: Gain, Level, Bass, Mid, Treble
3) MOD
Chorus
Phaser
Tremolo
Flanger
Vibrato
Univibe (combines chorus and phaser)
4) DLY
Analog
Ducking
dTape (I want to have a play with this as it emulates tape saturation, my favourite bass distortion)
Dual
Lofi
5) REV
Room
Hall
Swell
Spring
Shimmer
Cloud
6) CAB
1-15 for guitar
16-20 for bass (models Agula410, AgSVT410, DgDG212N, MbSway210, Tace412)
Same controls for all - Level, Lowcut, Highcut
There's also a tuner which can be put in either Mute or Bypass mode, and the reference can be changed from 440Hz. It responds quickly and is easy to use and accurate (I put it in series with my Zoom MS-70CDR+ and it was as responsive and easy to use, and very visible). The Android software is easy to use too.
It also allows you to load cab IRs and AMx files (AM2, AM3, and AM4 AFAIK) which are equivalent to NAM files - NAM files can be converted to them. That's something for me to try to see if I can get an octaver and a pitch shift emulated.
