I had the AFD 100 for a short period of time and really really wanted to love it. I didn’t bond with it at all. It’s absolutely a single channel head with options. The Vintage Moden is too, but found it way more useful. Had I had something like an underlined or Oscillator Siren, I’d have kept the VM and might get one again as it’s an awesome amp.
The AFD was way too bright and needs the right pickups and guitar to sound good. For what it is, it’s great but it’s not a versatile amp, if that’s what you’re after.
