The Nocturne ATOMIC BRAIN® AnalogBS-301 PREAMP for Guitar, Pedal Steel, Keys & Bass. Full Dynamic preamp booster in satin black w new OG LogoThis  all new version is now in a much smaller compact box, and single stomp! All the great sound of the DYNOBRAIN w/ an ABBY* mode that opens up the preamp for solo'ing or adding more punch/crunch to power chord. Wake up your guitar, hear your fingers through the amps speakers. Give that old amp a new reason to live :) 

A Full sonic spectrum, VINTAGE JAPANESE preamplifier that is a very reactive, and tube like dynamic enhancement for your Amp and DAW buss inserts! Notes bloom and chords ring out while keeping your guitar tone up front and pure. I've replicated a much improved, let me repeat it, Vintage Japanese 70's preamp from the ROL@ND RE-301 Tape Delay machine known as the Space Echo. that is now true bypass & loaded with hi-fidelity audio components

We've Improved the input impedence, extended the gain range & added a Bass cut that the original RE-301 didnt have, this aids in use with cranked small amp to keep the speaker from farting out AND when the Bass Cut is dialed back to 7 oclock, the tone sweep will give you a leaner, tighter modern flavor. Dial it back to 4-5 o'clock for the vintage full low mids of the original character and color. a "vintage-modern" contour if you will. 

All our preamps operate at 9v and 12v. I prefer to run mine at 9v for more texture and saturation at max gain.

note:

Average turnaround is 3 weeks at this time. it will be delivered via USPS.com Priority insured (international is DHL insured )when the build is finished. I make each one to order and the day I receive your order you are put on the build list. When the build is finished we send you a ship/track number via an email.

(*tech notes: ABBY MODE... this dB boost mode isnt acting like other drive boxes that employ cascading gain or double up on diode clipping . Its a bit of a unique approach to solve the request for a solo mode. It modifies the guitars impedance response.
The "ABBY" is opening wide the preamp gain range. Guitar solo's will stand above the band digging in at chorus intensity or even if at a turn around you want a cool melodic travis pickin pass.
The ABBY switch is taking your guitar from whatever level you have the NORMAL mode at and suddenly making everything like 35% more dynamic than it was (i dislike using "touch sensitive") so as you dig in for the solo the guitar is pushin into the amp or whatever is after it that much more. The more the normal channel gain is turned up, the more boost you will get from the "ABBY" mode. 

*toggle switches explained:

left toggle is a high presence cut that takes a little gain in that frequency down a notch. the right toggle shifts the impedance so in the up mode, it feels louder but its actually increasing sensitivity to pick dynamics.


The left toggle help in a number of ways:

1.The left presence cut smooths out the top end overcoloring when you are using dynasonics or other large bobbin single coils

2. also nice for reducing Piezo quack on acoustic instruments.

3.  useful when you have other pedals in front of it that tend to brighten your signal like a boss pedal. Boss and ibanez/maxon pedals have an "Always on" active line buffer that pushes a high presence signal through the pedal whether stomped on or off. When stuff like this hits the atomic brain, the atomic brain preamplies all other noise artifacts in front of it. Effectively doubling the unwanted frequencies or hiss or whatever before it.


The right toggle is beneficial for:

1.Master volume amps, as when you flip it into the up position ye ol' master volume amps get the same benefit as non master amps, that tend to sound better with full range preamps. its a fix'er'er for em. Plus lets you hear your fingers on the fretboard when raging the gain.

2. when using piezo pickups, they want to see a much higher input impedance at the front'ish side of a preamp pedal. this helps acoustic guitars and upright basses

3. electric basses get more growls w this flipped up as well, really cool when your the low end guy and you want the rest of your band to hear your notes instead of just feeling them.

extra feature, flip all toggles up, stomp on the abby..turn down the global gain control just a bit above unity gain and thin guitars are suddenly fuller versions of themselves w the amp. adjust the bass cut to taste, enjoy.

A Sunscreen That Checks Every Box!
I recently picked up the **Neutrogena Ultra Sheer Dry‑Touch Sunscreen Lotion **SPF 70 in the convenient travel‑size 3‑pack, and I couldn’t be more satisfied. Here’s why this product deserves every bit of its glowing reputation: 1. High End Sun Protection in Compact Form With broad spectrum SPF 70, this sunscreen offers robust defense against both UVA (aging) and UVB (burning) rays, making it a reliable choice for daily city exposure or weekend adventures .The travel-sized 3 oz bottles are perfect for on the go use slip them into your gym bag, purse, or carry on without a hitch. 2. Dry Touch, Non Greasy Feel The standout Dry Touch technology ensures a sheer, matte finish that absorbs almost instantly, leaving you feeling fresh rather than sticky or oily . Multiple reviewers on Amazon raved about its silky, non greasy texture, with one even saying “it goes on easy and did not feel greasy” . 3. Friendly for Sensitive & Acne Prone Skin Designed to be noncomedogenic, PABA free, and oxybenzone free, this sunscreen avoids pore‑clogging and potential irritants . Many users noted no skin irritation or breakouts even those with combination or sensitive skin reported smooth, comfortable wear . 4. Water Resistant & Durable Rated water resistant for up to 80 minutes, it holds its protective power well during sweating or light swimming, which is perfect for hot days, workouts, or errands in the sun . 5. Pleasant, Subtle Scent This sunscreen carries a mild, fresh scent that’s noticeable but not overpowering. A few reviewers appreciated this clean fragrance profile, making application pleasant rather than perfumed . 6. Affordable & Practical Bundle At roughly the price of a single regular-size bottle, the 3‑pack offers excellent value ideal for stocking up or sharing. Users frequently praise it as “a great value” and “perfect for a beach bag or purse” . A Few Minor Things to Note • Shake Before Use: Some buyers reported slight separation of formulas just give it a good shake to ensure consistent, smooth application. • Occasional White Cast: A small number of users noted a subtle white cast, primarily if not well blended, but most say it blends out cleanly and is barely noticeable . Final Verdict Neutrogena Ultra Sheer Dry‑Touch SPF 70 (Travel‑Size 3 Pack) is a rare combo of high-level sun protection, everyday comfort, and great portability. It’s lightweight, dries almost like nothing is there, and won’t clog pores or leave a slick residue making it a go-to for work, travel, workouts, and weekends. If you’re looking for a powerful yet elegant sunscreen that fits seamlessly into a busy lifestyle, this is absolutely it. I’m already repurchasing it and recommending it to everyone who asks!

Great Sunscreen
Love this sunscreen. What I like most is that it goes on very dry with zero greasy feeling or shine. The sunscreen is also scent free. I’ve seen several review where purchases stated that they received expired product. Mine arrived in January 2023 and expires February, 2024. I highly recommend this product.

Doesn’t stain clothes and lightweight
Something that always bothers me about sunscreen is how it stains clothing. I did not have that problem with this sunscreen. It was lightweight. It only had a very mild gritty feeling after having it on for over 8 hours and sweating a ton. Best sunscreen out there right now!
