I got mine from Andertons for £280. I’ve rehearsed with it a few times and will be gigging with it in a week or so’s time. Very impressed with the sound. The Mooers look like they’d do the job too but, obvs, with more real estate on the board. That would allow foot switching between amp models which isn’t possible with the Simplifier.
In my case, I do a mix of the signals from my pedal board, synth and guitar synth to balance the levels and send one signal to the PA, so I have the Simplifier velcroed to a music stand alongside a little behringer mixer. As a result, it’s an easy job (albeit the switch is a bit small and fiddly) to just flick between the different amp models.
