I love this thing......
.....but it's not perfect.
I had a ball today using this thing for the first time in my band. I ended each song in wild feedback. LOL! It's really awesome for that. It was also handy for holding long notes, like in the outro solo for Come Together by the Beatles. Those long notes often die out, like on the studio version itself. But with the Feedbacker, I could step on the feedbacker as I started each long note, and it worked perfectly. Feedback knob was set at around 10 o'clock.
I also liked the treble boost feature. It helps to make your solos cut through the mix without adding a lot of volume. The boost is also great for solos. It adds sustain and is easier to use that stepping on the volume pedal each time you want to do a solo or fill.
The bad is that the feedback feature can't be held down for very long before it develops a resonate sound like a flanger has. Maybe 10 or 15 seconds. Then you have to release the pedal and start again. I was hoping I could just leave it on and get sweet feedback for long periods of time through all kinds of phrasing. Instead it develops an added resonant quality that sounds kinda lame. Like you're playing in a bathroom.
But don't let that steer you away from buying this pedal. It's good for at least 15 seconds of feedback on one note, and the feedback sounds killer. And it's adjustable, from mild to wild.
The treble booster....not really what I was hoping for. I was hoping for more of an adjustable cocked wah sound, but it's not like that at all. Instead there is a very narrow frequency range to choose from and an adjustable hump that quickly goes way too far.
I wanted the early Tony Iommi sound, but haven't really found it with this pedal. But the treble booster feature is still very cool for other things. Like I said, it cuts through the mix, adds sustain, makes feedback easier, boosts your volume, etc.
Oh ya, LOTS of boost. Way more than you need as a rock guitarist looking for a pedal to boost his volume for doing solos. I set the boost around 12 o'clock. At 3 o'clock it was way too loud.
I've been a top 40 guitarist for 40 years. You can get these pedals for pretty cheap. It's definitely a very fun pedal. But it does take some patience to adjust properly and skill to use properly. It's the first pedal in my chain, as I use it to overdrive an already crunchy overdrive.
As for modifications, I might want to change the LED light to a brighter light. In daylight it was hard for my senior eyes to see if the pedal was on or not. And unfortunately, every time I wanted the feedback, it automatically goes into boost mode and stays there unless you turn it off again. Not really a big deal, but I think Boss screwed up there if you ask me.
My 2001 American Standard Stratocaster with whammy bar was just fun as could be with that feedback feature. I got a lot of Jimi Hendrix sounds with the feedbacker on and my whammy bar getting a workout. The feedback does follow the note! So it really does sound and operate like an amp that's just naturally feeding back. It's nothing like a Looper. You just can't hold it down while doing a long solo. Like I said, if you do that, it gets this flange style resonate sound, which isn't terrible, but it no longer sounds natural. It ends up sounding like you're playing in a bathroom or something.
Buy it! It really is the most fun you'll ever have with any pedal. It's not perfect, but it's a total gas if you love Hendrix style feedback.
Lastly, the feedback NEVER fails. Even on low and clean notes, if you step on that pedal, you ..... you are going to get feedback. So many times I figured I didn't have the volume to get feedback, but it always came through, and sounded very natural. It's very usable for any time you want some great sounding feedback. You just can't leave it on for very long or you end up with that bathroom reverb sound.
Peace!
