In summary: worth it :)
Each multieffect is missing something that is in the other.
I use three guitars with one Ibanez RG320 active pickups (EMG 81/85) for metal, Tony Iommy SG with JB pickups
for rock and a noname strat with Ironstone pickups.
Randall Diablo amp with 112 cab.
Amplifiers model:
The vast majority have proven themselves, I mainly use the Bogner, Mesa, VOX types.
There could be more :)
Effects:
They are not very outstanding, although there are some that are quite usable.
EQ is very good to use
IR:
In my opinion, the best part. It reproduces the sound of thirdparty irs extremely well.
Factory IRs are not bad either. What I'm missing is the 10 IR slots, there could be more but maybe then
when updating the firmware.
PC editor: Works perfectly in every way, almost everything can be used.
And it works flawlessly!
Many people complain that it is noisy. Well, with the right setting, there is no noise.
If so, be careful with the gain and use the nois gate.
