I bought this on a whim when Otter made an announcement via Facebook. It's taken me a while to get around to using it because, well, reasons. Anyway, I'm going to give my thoughts on what is a great product, but also one that has some downsides too.
PROS:
It arrived promptly and was beautifully packaged with some nice candy and instructions
It's extremely well built and presented. It fits the aesthetic of the Tonex pedal well and dovetails nicely when mounted using the velcro strips provided
It's easy to set up and use, and does exactly what it says on the tin. I'm using it for "bank changes"
It doesn't make the Tonex pedal's footprint too cumbersome.
CONS:
The price. I knocked off 1/2 star for the cost which, at £78, is quite a bit considering what it does (or doesn't). Which leads me to
It's limited functionality. Once it's working you immediately find yourself thinking "wouldn't this be great if you could switch in/out reverb on the same preset?" or similar. Further, in light of IK recently announcing the planned addition of modulation and delays, I find myself thinking, how good this would be with 3 or even 4 switches (1. bank up, 2.bank down, 3. modulation on/off, 4. delay on/off). So I've taken off another 1.2 star for that too.
But overall, I love the concept and execution. I just wish for and hope it one day has a little bit more...
