AER compact 60 question

[Sandstorm]

Wanting to get a dedicated acoustic amp for home usage and ultimately live and this seems to be the benchmark for a lot of players and reasonably priced for pro level type gear.

My question is, it has built in reverb, chorus and delay but no parameters to adjust for any effects other than the mix level.  Any chorus, reverb or delay pedal often has 2,3...4 knobs or more and guitar players can be rather particular about tone and adjustments so how can there be no parameters to adjust on those effects?  Especially delay where you want might to adjust the tempo to the song so everything doesn't sound like a mess.

I unfortunately can't answer your question, but I will say that the AER compact 60 has a stellar reputation with high quality German engineering. Tommy Emmanuel toured with that amp for many years. Hopefully someone with experience with that amp can chime in. I personally would love to own that amp.
