Thanks, Ellen!
My pedal steel amp has a headphone jack but, honestly, the sound quality coming from it is pretty awful. So, I've always kept an eye out for a headphone set up that would sound close enough to my regular steel sound for practicing (silently for those around me).
Sometimes a pedal steel player will practice acoustically; that is, without plugging into an amp, just relying on the acoustic sounds coming from the physical instrument. This is possible on a traditional PSG because the pitches of the strings heard acoustically match what would be coming from an amp if the steel were plugged into one.
However, as mentioned on the FAQ page, the OnePSG requires playing through an amplifier or through some sort of practice headphone set up. Why? Because the pitches coming from the physical strings (open or changed with a pedal/lever) rarely if ever match the pitches coming from the amp. That is, after all, the whole point and the power of the OnePSG.
By the way, this would never be a problem on stage, because the amp, even at a low volume, would be loud enough to drown out any acoustic sound. But what if you don't want to disturb someone in the next room?
And so, my search for a solution (reasonable sound, not terribly expensive) has been more urgent so that I could suggest something to any player of the OnePSG.
Well, I recently saw a video by Ellen Alaverdyan, the young bassist and inspirational musician/artist (if you don't know about her, check out her here, and then subscribe to her YouTube channel!). In it she reviews a product from Positive Grid, the Spark Neo headphones.
Since Positive Grid wouldn't just give me Spark Neo headphones to evaluate when I inquired (Heck, why should they? Who do I think I am?), I purchased a set. I've only had the item a few days, but it seems to do the job nicely. You can even use them as Bluetooth headphones at the same time to listen to tunes or tracks from another device (computer, phone, etc.) so you can play along.
It has lots of other features too. And though of course the whole app environment is geared towards guitar and bass players ... of certain genres, it didn't take me too long to configure a sound that is relatively clean, rather than a super distorted, outer space, metal sound. ;)
