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.

This stuff works!!
Scent: Fragrance-Free - Standard Size
This set has been the absolute best shampoo, lotion, and ointment for my little one going through a tough spell of baby acne. The ingredient list is clean, and worked miracles quickly. Baby’s skin was so soft, the redness disappeared within days. After just the second wash I could really notice a difference. Thank you Tubby Todd!

Perfect gentle routine for newborn skin
Scent: Lavender Rosemary - Standard Size, Scent: Lavender Rosemary - Standard Size
We started using the Tubby Todd 3-Step Baby Bath & Skincare set when our baby was just weeks old, and it has been amazing for delicate newborn skin. The Hair + Body Wash is extremely gentle and doesn’t irritate or dry out the skin. It rinses clean and has a very mild, pleasant scent. The Everyday Lotion keeps our baby’s skin soft and smooth without feeling heavy or sticky. It’s perfect for daily use after bath time. The All-Over Ointment is great for extra-dry areas, especially around the cheeks and legs. It creates a protective barrier that helps prevent dryness, especially in cooler weather. We appreciate that this brand avoids harsh chemicals and focuses on clean, baby-safe ingredients. This routine has become part of our nightly bath time and has kept our newborn’s skin healthy and moisturized. Would absolutely recommend this to new parents looking for a safe, gentle skincare routine for their baby.

It didn’t work for my baby
Scent: Fragrance-Free - Standard Size
Update on my review: gave it 5 stars because the customer service is great!!! Thank you uso much! I’m sorry this product didn’t work out for my little one. But thank you for having a great customer service! I’ve been using the products for about a week now and haven’t noticed any improvement in my baby’s skin. I do appreciate that the ingredients are clean, fragrance-free, and that the ointment is thick and suitable for eczema. However, I’ve seen other reviews mentioning results within a few days, and unfortunately, that hasn’t been my experience. For me, it wasn’t worth the money. At first I thought my baby had ringworm but I took him to his pediatrician and she said it’s a mild eczema, I don’t want to do steroid lotion, I purchased this hoping it would help and it hasn’t

Before and after baby newborn acne
Scent: Lavender Rosemary - Standard Size, Scent: Lavender Rosemary - Standard Size
As a first-time mom, I was really stressed when my newborn developed baby acne. The doctor told me it’s normal, but it was still hard to see. I tried other products like Nutella, but unfortunately, nothing seemed to help. Then I decided to try this product — both the face ointment and the body lotion — and I’m so glad I did. My baby actually loves it! Unlike other lotions, it doesn’t feel cold on her skin, so she no longer cries when I apply it. The biggest difference was how quickly it worked. Within just 2 days, her acne improved so much. I was honestly surprised and relieved. I definitely recommend this product to other parents. For reference, my baby is Asian, and it worked very well for her skin.
