Electro Harmonix KEY9 Electric Piano Machine

just a toy

The biggest issue is a latency - there is a considerable delay between hinning the string and hearing the result. It absolutely kills the fun. So, it can be used in some parts of the song during the life sessions, but I cannot imagine anyone would enjoy just playing or jamming with it. For good synth tones I have few synths at home.

Too pricey for what you get

It's just too pricey for what you get. 100 euros off and I wouldn't have send it back. There are only a few useable sounds. The rest don't sound like the real deal, or gimmicky. Would be perfect for a lower price point.

Very faithful to the original sounds, super fun!

An absolute monster pedal. The Wurli sounds legit. Tracking is solid, responds well to quick licks. Controls are more than adequate to tweak the sounds to feed your fancy. Live and studio application; this pedal works well in both environments. The pedal itself is sturdily built. Can't really think of any cons/area of improvement. EHX for the win!

Piano Machine

I like this. A great way of getting piano sounds from a guitar.

The tracking seems very good, for chords or single notes.

Obviously some sounds are better than others, but maybe you'll like the ones I don't,and you'll need to think like a keyboard player, rather than a guitarist. No 2 tone bends or tremolo divebombs.

I use it for putting rhythm parts on my songs, and it sits nicely in the mix.

Good Pedal

I use this pedal at the very beginning of my pedal chain to act as a buffer and at the same time to get the best possible sound out of it. There are so many types of inspiring sounds that you can get out of this pedal but it will take some time , also it helps if you have an EQ pedal after it.
