Three Reverb and Trem Modes:
We’ve combined the most popular ‘Verbs and Trems into three different pairs. There’s nothing quite like the syrupy smooth sound of our Plate Reverb combined with Harmonic Tremolo.
- SS – Spring Reverb and Sine Tremolo – Classic black panel amplifiers had spring reverb followed by a sine wave tremolo (at the power tubes)
- PH – Plate Reverb and Harmonic Tremolo – Smooth reverb with swampy harmonic trem, what’s not to love?
- PV – Plate Reverb and Pitch Vibrato – Vocal smooth vibrato with other-worldly reverb.
Reverb – Sounds and Controls
- Spring Reverb: tube amp spring reverb – we simulate every detail of that classic vintage reverb sound.
- Plate Reverb: bright, smooth reverb from a thin vibrating metal plate.
- Reverb Decay: (Alt feature) Hold REVERB/ALT SWITCH down while adjusting Level knob.
- Reverb Tone: (Alt feature) Hold REVERB/ALT SWITCH down while adjusting Rate knob.
Tremolo – Sounds and Controls
- Sine Wave or Volume Tremolo: Sine wave tremolo simply adjusts the volume of the signal up and down.
- Harmonic Tremolo: Just like tube-amp harmonic tremolo, your guitar signal is phase-split and filtered, almost like a phaser.
- Pitch Vibrato: Bends the notes out of tune, you control how far and how fast.
- Alt-Control-Tremolo Boost Volume: Hold REVERB/ALT footswitch down while adjusting Depth knob.
Stunning Design and Ease of Use
- Artful Electronic Circuitry: Housed in a proprietary angled aluminum enclosure for simplicity and durability.
- We stand behind EVERY Keeley pedal: Proudly Designed and Manufactured in the USA.

An improvement over the original product, but could be better
I had used the original Xylimelts a few years back for my night time very dry mouth. They worked very well, completely dissolving overnight, but they caused sores inside my cheeks. Recently I discovered this new version which was purported to be made without the offending ingredients. They don't work quite as well, as they don't completely dissolve, but so far haven't caused any irritation. My mouth isn't completely parched as it was without any product, so it is definitely better than nothing. There is a gel-like residue in the morning that needs to be scraped off the teeth. I think Oracoat has some more R & D to do.

These work well!
These work to keep my mouth moist for hours. The only downside is the glue stays in your mouth till you can scrape it out with your finger. I thought it would dissolve but it didn’t. Very grateful to find something that moistens my mouth for so long though. They’re easy to use too. Taste slightly sweet but otherwise I didn’t notice anything.

Xylimelts Sensitive
I was sensitive to the regular Xylimelts after a few months use. Painful gums and hives inside my lips and cheeks. The sensitive version immediately corrected the problem and I’ve been using them without issue for nearly a year. The product is a lifesaver for drymouth that occurred when I was sleeping.

Best that I have found for dry mouth.
These are the best for dry mouth at night. They mostly stay stuck. I say mostly because I have had a few come apart. I think that was my fault.

This book came highly recommended by a fellow entrepreneur I trust, and I started listening to it almost immediately after purchasing—and I’m so glad I did. Who Not How has completely shifted the way I think about growth, productivity, and collaboration in my business. It's now a staple recommendation I make to all the entrepreneurs I work with. It’s insightful, empowering, and essential for anyone looking to scale their impact by working smarter—not harder. If you’re building a business or leading a team, this one’s a no-brainer.
Pros:
Powerful Mindset Shift: The central idea—stop asking “How can I do this?” and start asking “Who can help me do this?”—is simple but transformative. It helped me rethink delegation, collaboration, and building a team.
Actionable for Entrepreneurs: As someone who works with social entrepreneurs, this book now tops my list of recommendations. It’s a game-changer for anyone feeling stuck, overwhelmed, or trying to do everything themselves.
Engaging & Easy to Digest: Whether you’re reading or listening, the content flows well and feels conversational. It’s packed with real-world examples that make the concepts stick.
