TC ElectronicBRAINWAVES PITCH SHIFTER Exceptional Pitch Shifter with Studio-Grade Algorithms, 4 Octave Dual Voices and Groundbreaking MASH Footswitch

Excellent innovative harmony and pitch pedalVery intuitiveExcellent build with great tone versatility

I’ve tried most octave, pitch shifters, harmonizers… type of pedals ranging from all brands. This one made it to the pedal board. Can be a little boring at first until you start to mess with each pitch, knob, and setting. It also can be a useless pedal unless you like funky sounds and unique riffs, than you could live without this or buy a cheaper octave/pitch. But it’s by far one of my most favorite to play around with especially with a nice reverb and delay setting!

It's a great pedal. It's amazing that there is finally a pedal that will allow me to get rid of those godawful vibrato bridges and do all my pitch bending tricks on the floor. And the mash button technology is a welcome alternative to those big, clunky expression pedals that more than double the effect's footprint.But one of the things I need it to do is drop my tuning a half step. This is a very common thing for guitarists and I feel not an unusual request. It doesn't do this out of the box. The smallest interval it offers is a whole step. It can be configured by downloading the toneprint app, connecting to the device, and building a half-step setting for one of the custom slots. But I found this to be a little difficult and time-consuming, and I'm an IT professional with a B.S. in computer science. Sometimes this kind of tweaking is a fun learning experience. But when it comes between me and Couldn't Stand the Weather, it's annoying.If you're buying it to play around with and experiment with different tones, you're going to love it. If you're buying it to do a specific thing you already have in mind, you're still going to love it. But you need to set aside a cup of coffee and a couple of hours to figure out how to get it to do that thing. (Which it really should have been able to do out of the box.)Unfortunately, I won't be selling my Digitech Drop just yet.

Tracking is not as good as they say it is. It’s ok at mono not good at poly. Its really quite for some reason I couldn’t figure out. DONT buy pedals from Gearnuts. They charge shipping and restocking when you return their not so great pedal.

A funky edition to the board. I dig it may not be fire everyone but has a ton of features

This pedal is not for the beginner building their first pedal board. But it's an amazing pedal! Worth every dime.

Poor tracking when using this for violin generated bass lines.The pedal I’m looking to replace, the EHX Pitchfork, tracks really well but has that white noise problem a lot of online users have noted. While the Brainwaves is quieter, it tracks so badly that at times it almost seemed like it was throwing out notes at random. If the Pitchfork & Brainwaves were combined a great pitch shifter might result. The search continues—maybe the Pitchfork Plus is the answer.In addition the BW interval settings were off in places—the 4ths were in the 5ths slot, for example. I probably could have lived with that quality control goof but the bad tracking problem made me reach for the Amazon return button after a few days. Even experimenting with the Tone Print feature couldn’t help the poor tracking. Btw that Tone Print feature worked badly on a recent iPad. I had to go to the laptop to use it, and it worked well there.

Another amazing pedal. Not your pappa's pitch shifter!
