Ok so I seldom use this in my rig, mostly tune up then take it out of the rig but you can leave it in their if you wanted. It features a bypass so this could be left in without affecting tone but I choose not to. To my ears it does not add extra hum to the amp but my friends got one that adds plenty so his rig. Might be to do with amp quality or just hit on miss as to whether you get a good one or not.
Overall Impression — 7
This pedal is great if you simply tune up with it and go. It does the job of all its expensive counter parts exactly the same. I wouldn't use Behringer for OD pedals ect but for something that I'll be using only to tune and not a key part of my rig this makes perfect sense. What would I change about it? 1) I'd send the pedal in a box, not in some thermal plastic like a toy. 2) The LED on the front is so freaking bright it can be difficult to see the read out.
Reliability & Durability — 5
Well... Behringer... Yeah. Ok seriously lets not judge a book by its cover, iv had mine 6 months, it works great and I simply could not go without it, specially usefull when tuning to alternate tunings. I use a power supply for all my power so cannot comment on how fast this pedal munches through batteries but if you gig it without fresh batteries... Not really the pedals fault is it? The housing is plastic and I'm fed up of people moaning about this fact. Its cheap and affordable and its not a pedal you stomp on all night, only once or twice so why does it matter? Also if your on a budget (student here) they just make so much sense. The ONLY issue as far as reliability goes is that sometimes it takes just a little to long to register what note I'm playing.
Ease of Use — 8
Ok so its a chromatic tuner, fairly straight forward I guess plug in and go. Unless your a complete neanderthal you should be able to aptly work this one out. Just kidding there's more to it then that, everything is explained in the leaflet depending on whether your in chromatic mode or not. If in chromatic it will be the note shown is the note your playing. For sharps it has a dot after. So C# on the display would look like "C". It has several modes to choose from; chromatic, guitar (standard), (from standard), (from standard) and bass (standard).
