One pedal I've wanted for some time, but either had other things I wanted more (Or other stuff come up)--is an octave&/or pitch type pedal.
I've tried a lot of them out over the years--and some I didn't get because they tracked poorly. Some tracked well at some pitches, but poorly in other places.
Some were noisy.
Some have an auto-tune type sound to them--at least on some settings.
Some were good, but too expensive for me. (Sure I could save up longer, etc--but I didn't feel right about spending over $200 (& in some cases over $300 + up) when I primarily play at home.)
So recently I saw some online reviews for the TC Electronics SubNUp pedal--and it looked interesting (& sounded great)
So I checked it out --on two different occasions--with different guitars & basses.
It fit what I wanted--so yesterday I picked one up.
I just got it, so there is that "Honeymoon" period we sometimes have with gear.
But it has a classic mode (Older style Octaver where if you play 2 or more notes together you confuse it), a Polyphonic mode--where you can play chords or single notes--and best of all--the Tone Print mode--where you can download an app to add a third setting--it comes with one that is an organ kind of sound.
The app & the sounds are free too--so that's cool.
They also have an editor for it to create your own sounds or tweak existing ones--I have't done much with that yet though)
But with the sounds available (You can switch them via the app& a smartphone) this pedal will give me a lot of variety in what sounds I can get--so that was a selling point for me.
I'll review it once I've had it for a while & used it more--but it is a cool pedal--and GAS is subsiding a bit (Although a pedalboard would be a great next purchase for me)
I haven't tried it on my Mandobird yet--but that should be cool too.
