The Nocturne ATOMIC BRAIN® AnalogBS-301 PREAMP for Guitar, Pedal Steel, Keys & Bass. Full Dynamic preamp booster in satin black w new OG Logo.  This  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.

Simple yet easy must have for discerning coffee drinkers
Color: Black&Silver
I seem to never get the same results from my coffee machine and it varied even more with the new brand that we just bought. I now have to make more adjustments with the water temperature, based on age, type of beans, etc. That affects the amount of ground dispensed and consistency in the shot until I get a new batch dialed in. So the only way to regulate these changes is to weigh both the beans and water. Using this little scale has made things easier, less frustrating and more predictable. What’s awesome is that it will automatically begin the timer with the first drop and stop when the pressure remains constant. Simple yet easy and super convenient. If you are looking for a great little digital scale this should do the trick. Highly recommended.

Great Digital Scale!!
Color: Black&Silver
The Maestri House S2 scale has been clutch for dialing in my espresso shots. Memphis heat or not, this thing stays accurate and steady. The timer starts up quick, the readings are fast, and the compact size fits perfectly under my Breville without feeling cramped. It’s built solid, charges by USB‑C, and the precision really shows when you’re trying to get that perfect pull.

Has fit perfectly into my morning espresso
Color: Black&Silver
This seems to me to be an excellent small kitchen scale. I am new to the complexities of espresso making and have begun using this scale every morning to measure my dose and output. It is working just fine. Easy to operate, keep clean and store. I did not give it 5 stars because I have limited comparisons but I don’t expect and will not bother looking for anything better.

Perfectly fits what I needed for my espresso habit!
Color: Black&Silver
This Maestri House mini coffee scale is a great little tool for espresso and pour-over. The size is compact enough to fit under a portafilter or cup, and the 0.1g accuracy makes dialing in coffee much easier. I like the built-in timer, rechargeable USB-C battery, and clean black-and-silver look. It feels precise, practical, and easy to keep near the espresso machine. Great value for anyone who wants more consistent coffee.

Maestro House Mini Coffee Scale
I have begun to drink tea, pu’erh tea to be specific. I have several varieties and I have had a problem with getting consistent results. The varieties can be very different in size depending on when the leaves are harvested (leaves harvested in spring are much smaller). So the easiest way to get consistent results is by weight. This scale is very easy to use with a ceramic tea scoop, set the tea scoop on the scale, zero it out and add tea leaves. This has made my results much better, without the wild swings in strength I had been getting before trying to eyeball even measures. This scale gives me accurate measurements to one tenth of a gram.
