Excellent recording tool!

I have this alongside the Strymon Iridium and Tech 21 SansAmpGT2 and it does hold its own next to them! The amp sims are great and the advanced features (XLR outs, FX loop) are taking it to the next level. My favorite is still the Iridium (soundwise), but these few distinctive options make it better suited for ampless live gigs.


One of the best things I've ever bought

Cannot stress enough how good this thing is, not only in it's sound but how ergonomic it is; so many useful features yet so compact. The sound of this thing is insane, the flexibility in cabs, mic positions and EQ etc lets you twiddle for hours, full stereo FX loop and stereo out. If your thinking of buying this, just buy it and ponder no longer... It's so sick hahaha

My only one tripe is that it would be even better if it was stereo in and I could run my synths into it, but is a guitar pedal so I'll let them off - 10/10

I needed a amp/cab sim this delivers
its like a swiss army knife integrates well on my pedal board it does so much and its easy to use sounds great

I was very happy with the tonal range and flexibility of the unit in mono and stereo and does a great job with headphones I fed it with a clean patch from my line 6 X3 Pod works very well all I need now is to start recording again


Simply amazing

The Simplifier unit it compact and fit neatly alongside pedals on my board. The build quality is good as far as I can tell. I like the retro switches and styling. It is a compact unit, so could be considered fiddly by some, but for me its perfect.

The tones are really really good, the gain doesn’t go into full on metal territory, but does really hits the spot for an overdriven amp tone. The amp sims give enough variety, the power amp / cab sim settings are more subtle. The mic placement knobs widen up the sound nicely.

One thing I love about this unit is the effects loop. Being able to put my delays and reverbs in the loop again, is a great feature.

Connectivity wise it covers all bases - i.e. XLR and jacks.

All in all I love this little unit.
