Why was my package refused?
There are a number of reasons your package could be refused by us, including:
I've been looking for a bass octave pedal for some time. I wanted a standard size pedal and didn't need an octave up. I also needed something that wouldn't go all wonky on the occasional low note. This is an octave down pedal with two separate voices. The left is a very synthy sounding octave, the right is more natural sounding too my ear. It tracks very well down to low G, and even down to E it doesn't jump all over the place.
After trying several octave down pedals, this is the one I believe sounds the best for me; and I appreciate that it fits on the front row of my pedal board - a bigger pedal wouldn't have.
Picked up to be able to add sub-octave content during times where I play more melodically or have some effect cutting low end.
Has two different sub-octave sounds, I prefer girth as it is smoother sounding. Growl sounds a bit like a low frequency oscillator from a synthesizer, meaning that the frequency is so low you can hear the waveform clearly.
Both of the sub-octave settings lose smoothness as they are turned up, which may be nice or not depending on your taste. In a solo context this could be annoying if you just want to add lower frequencies without altering the timbre of your sound. However, in a full band context it is likely to not be nearly as noticeable.
Having separate level **** for dry, growl, and girth is an advantage over blend, as you don't need to compromise your original dry volume to add more sub.
I haven't used the mid button much, but my impression is it will bridge some of the gap between your dry tone and the sub-octave tones at the expense (or plus) of boosting the non-smooth sounds of the sub-octave tone.
Works great, no doubt.
The MID button almost makes the octave sound close together and seems to bring out the GROWL more. Can produce a distinctive octave sound and even make it sound a little dirty. Cool. Very dynamic, even with fast playing.
If I had to change one thing, it would be to let the range sound even cleaner than its cleanest. Still, makes a good sound worth having.
For the price, can't complain.
In case you weren't sure, this gives your bass an octave BELOW the note you play.
Tracks fast and true, and the dry blend makes this pedal entirely practical, which i what I like about MXR pedals.
My only gripe is that it seemed to struggle tracking my low E. Just sounded like mud to me. The guy in the shop claimed it was my amp and that the pedal was tracking fine, but I'm just telling you what I heard. Could've been the amp.
But try it yourself. Every other note sounded perfect and amazing to me.
