DESCRIPTION 

Three Flavors of Authentic Tube Tremolo, at your Feet

Evolved from our flagship Astra Modulation Machine, Flow Vintage Tremolo gives you three flavors of tube-driven wiggle and shake — from old school to modern — in a dapper, compact package.

Dharma: Experience Thick Harmonic Tremolo

Immerse yourself in the chewy throb of early '60s American "brown" amps, and add a syrupy mix of volume fluctuation and phase shifting — far beyond the original circuit — that's perfect for vintage soul, surf, and even Uni-Vibe textures.*

65: Indulge in Perfect Tube Amp Tremolo

Play through an exhaustive end-to-end emulation of a classic 1965 American tube amp's optical tremolo circuit, and get the pulsating shimmer of the most famous "vibrato" ever created. Sounds just like your favorite old record.

Square: Add Modern, Choppy Textures 

Built from the ground up using our own virtual optical photocell, get the rippling beauty of square waveforms and dive into rhythmic trem effects that enhance any genre, from modern pop and R&B to blues and indie rock.

Get the Authentic Tone of a Tube Preamp

Flow gives you the warm, complex sounds of a tube preamp — in this case from early and mid-'60s American combos — so your tremolo effects are more present, three-dimensional, and musical.

Paint the Town with a Rugged, Compact Stompbox

Built for years of trustworthy performance, Flow Vintage Tremolo gives you switchable true/trails bypass, tap tempo, and "make up gain" Volume control to ensure your tremolo effects are heard loud and proud for years to come.

Best chew toy we have ever purchased.
Flavor Name: Classic, Size: Large
My moderately active 80lb Lab - Pit mix has been steadily working on this bone for over a year. He doesnt chew it every day but he does regularly chew it for 30 or more minutes at a time. He has only been chewing on the smooth end, and the only wear it shows is a slight thinning and some grooved tooth marks. It has not had any chunks come off, and has never developed any sharp edges that make it hard to play with. It has never smelled or gotten slimy. It has never triggered resource guarding with him, but he likes it enough that presenting it to him will often get him to settle down and chew when he is in a rambunctious mood. Its size and shape allows him to hold the textured Y end with his paws while chewing on the smooth end. All in all a fantastic toy!

Happy Doggo
Flavor Name: Beef, Size: Small
He immediately loved it. He doesn't take to bones quickly, but this one caught his eye. He's a 35 lb shepherd mix, and loves antlers, and chews pretty hard. I love that it doesn't smell, and havne't seen or noticed flakes. Overall would recommend.

Excellent product, highly recommend
Flavor Name: Classic, Size: Large, Flavor Name: Classic, Size: Large
So glad I came across this brand that uses actual edible material instead of the plastic nylon! All of our dogs love the nylon chew toys, but it's so bad for them to eat the little plastic bits! I got the large one & it is VERY large! I actually wish they had a medium one, one in-between the large & small ones as an option. But our dogs still love the large one, just harder for them to carry around & boy is it loud each time it gets dropped on the hardwood floor. It's big enough both the pups can chew on it together at the same time & do just that. We've had it for a couple months now & they don't chew on it everyday, but a few times a week I'd say & it's a tad bit softer than the nylon chews, but I'd say it's held up very well!

Dogs love them
Flavor Name: Beef, Size: Small
My two pups are power chewers. These bones are great! There’s no smell and pieces don’t come off like other bones. Although I am not a fan of the sound it makes when my dogs chew on them (nails on a chalkboard sound to me) they love them and it keeps them entertained. They are extremely hard so I limit their chew time (only because I can’t afford a trip to the vet if a tooth gets cracked) overall satisfied with my purchase, both myself and pups!
