DropTune

This is a simple pedal which polyphonically lowers your guitar tuning in 1.2 step increments, down to 3 1/2 step from your original tuning. There is also an octaver built in, and a trim dial which helps control the incoming signal from the guitar.

There is a toggle button to quickly switch between your original tuning and your drop tuning and a hardwired bypass for when the unit is not being used.

It runs off a supplied power adaptor, but doesn't allow for the optional use of batteries, so I'm going to mark it down on that basis only.

Generally I'm impressed with the sound of the pedal. Some reviewers have commented on the pedal changing their guitar tone adversely, and latency issues, and yes it does do this to a small degree.

I think the user needs to know what they expect from this pedal. This is an artifical way of down tuning a guitar, so it will never sound the same as actually manually down tuning the guitar itself, however, it does get extremely close.

The notes track very well (double checked this with a tuner) and it picks up all the nuances of your playing IE: hard and soft picked notes, harmonics, squeals, sustain etc with no clipping.

It can also cope with single notes, power chords, full chords and fast soloing.

I must note here, that to get the best from the pedal, you need to play notes and  chords acurately, but this is a good thing as it will only improve your playing

You do get a little more bass in your tone the lower you go with the pedal, but the same would happen if you tuned the guitar down anyway as the lower frequencys take over. This can easliy be sorted by tweeking your amp settings

There is a small amount of latency in the output, but this ranges from vertually nil at 1/2 step down, to a small amount at the lowest setting. This isn't really a problem, as it feels more like a slower attack on the note due to slacker strings, the same as you would get from being tuned down that low anyway.

I did noted that on the lower tuning settings, the sound seems to blend with the octaver a bit and become more processed, but you still get a very usable sound.

The octaver function is good, but there isn't any way to alter it, as you might do on a dedicated octaver pedal. I don't tend to use octavers anyway, so it's not really a problem for me.

It seems sturdy enough. Metal casing with plastic user interface.

Very easy to use. Plug guitar in, output to the amp or other effect pedals.

Set input volume with the help of leds.

LED light tells you what setting you are on and if the unit is in operation or not.

Not had to use them yet.

I play in a few different tuning and had different guitars permanently set up accordingly, however, I was getting bored playing the same guitar for the same songs, so I thought this would be the answer.

So far im very happy with it and it allows me to set up my guitars the same and choose which ever one I want to play in whatever tuning I want, with no real compromise on tone.

The only thing to bear in mind is that it wont change a standard tuned guitar in to a dropped D guitar, so that still needs to be done manually, but for overall down tuning, this is perfect and has allowed me to make more use of my guitar collection.

By the way, I have been playing 18 years and extremely fussy about my sound. I did have concerns over whether or not this pedal would work as well as advertised, and I think it does. Its not perfect, but it is very close and extremely usable.
