The  JR BARNYARD® (( color: Cola these ship June 30)
Pre-War Hot Preamp ( 1930's-40s octal tube amp character pedal). Inspired by my Moonshine'39 amp a repro of the 1939 Gibson EH-150 /185 pre war tweed amp and its octal tubes. I've created a textured hot club style preamp to garner those early Charlie Christian flutey reedy amp tones to Texas Playboys Junior Barnard and Eldon Shamblin dirty octal tube swingin texas blues. More or less designed to emulate the preamp circuit of the Gibson EH-150 / EH-185.

Looks like we've got more than just jazz and blues guitarists using this lil amp in a box character pedal, now. Blues Harp players. acoustic, country, alt rock and steel guitarists, as well as bassists and keyboard players are plugging into the Jr. Barnyard hot pre amp!

Standard model (single stomp), a new single stomp version w a blend control between the normal and mic channel plus a smaller compact size!! Much more versatile to boot!

With so many players gravitating toward easily mobilized rigs, be they compact nice solid state amps like Quilter, Milkman,etc or direct to house units (FRFR) like the Strymon Iridium, helix stomp,etc w IR (impulse response) tech.. the player can feel removed from the tactile response they've grown accustom to w a tube amp's dynamic interaction and interplay between clean and "edge-of-breakup" w the guitarists fingers and speaker. Even more so with roots musicians who crave that tweed response, or even further back with octal tube amps reedy bark.   

I've come up with touch sensitive solution with both my Jr Barnyard Hot Preamp and its flagship the El Pescadoro, that adds a pre-fender, Chess records era dual channel reverb that brings chamber and plate reverbs from that late 40s-50s era of reverberation. you can read more about it on my website here: https://www.thenocturnebrain.com/collections/pedals/products/el-pescadoro-reverberant-hot-preamp

the ultimate jazz, jump blues & western swing pedal. some are using it for honky, surf and shoe-gaze. :) 


(handwired original version is also avail as an upgrade option, choose from dropdown window)

Some folks call this a vintage Octal Tube Amp in a box as you can pull off the classic 30s Gibson octal tube sound from most any amp or even straight to a PA system (assuming you have a decent soundman). It aims at giving you the texture and dynamics you hear and feel from that pre world war II era gibby ES150-185 amps. (if you want a full on replication of an actual tit for tat octal tube amp, I make the Moonshine'39 octal tube amp based on my vintage EH-185 amp built late in 1939 which literally has the EH-150 stamp on it still.)

https://www.thenocturnebrain.com/products/moonshine39-combo

the basic sound easily dialed in from this class A discreet preamp is that punchy honky almost reedy/flutey (no more eee's pleeeze) late 30's and 40s swing sound, like Oscar Moore, CHarlie Christian, and (contemporary) Whit Smith are found here. ..or crank it up for full on chess era wooly 50s chicago rhythm and blues. (be sure to check out the EL Pescadoro if you want that leonard chess studio chamber/plate verb added:

This Transistor (BJT not FET, edit) based preamp uses a mix of imported Soviet germanium & Fairchild silicon diodes at its core with other sexy components like NOS Mial Caps, NOS Cornell Dublier & Mullard and/or Wima film caps, (NOTE:handwired version uses pcb through hole components, standard version uses mini component SMD circuitboards) Switchcraft jacks and hand wired leads from the circuit board like a vintage american amplifier. This preamp was made to give your instrument and amp the character response of hot octal tubes and field coil type amplifiers of the 40s into the 50s. Think Chicago Chess and Checker label recordings as well as Memphis Stax recorded amps.


I've had players asking for a *junior barnard & *charlie christian type of "warm cook'n" preamp that will keep the transparency of the instrument intact and work w a variety of backline tube amps.. so thats what I ended up with here with this preamp.

It has a Body depth switch (deep & Flat) and Bright switch for a variety of guitars, mandos,ukes, banjos,dreadnaughts..it just flat out brings you into the front of mix with reedy vintage warmth and definition like you hear when the musicians of the *Texas Playboys were asked to floor it w/ a solo by ol' *Bob Wills. I'll even go so far to say it will help Gypsy Jazz players comp that snarly Django amplified tone.
  I added a second channel that blends in the hotter mic channel of the EH185 to it so I could dial in more texture and finger tone for my vintage style big bobbin single coil guitars. (thats the stomp switch on the left) too boot! I want that Fatboy Rag kinda low down n dirty sound from my guitars that I can click on and off at will from the fairly clean tube amps I perform with.
This pedal is True bypass of course, powered by a standard *boss style 9V DC adaptor (no power supply adapter included, requires audio quality 9v DC power supply ONLY!! ) 

Non-USA players note: if you are in EU/ UK, 230v mains want to see the Boss PSU230 9v DC power supply.

FWIW regarding control set up:

I keep it in bass mode for the guitar honestly, as it makes it more authentic "wooly" in the low end, and I keep the switch flipped up as that cuts some of the presence but adds another gain stage in that frequency. W the volume at 11 oclock to 1 oclock w the blend control around 10 oclock, thats pretty much heaven for me.

This is what the controls are all doing:

left switch is a presence cut, right switch is bass or guitar mode. Left knob is volume, right knob is a blend knob between two channels. all the way to the left is the clean/normal channel and all the way to the right is the hot/mic channel. At about 11 oclock the hot channel begins to blend into the clean channel.

Rejuvenates your Robovac, but one caution
I was a little wary buying third-party aftermarket parts for my Eufy Robovac 30c, however, all the parts in this kit are virtually identical to OEM parts. I replaced all three brushes and all three filters and let it loose on my Golden Retriever-inhabited living room. I can honestly say the result was a 50% increase in the amount of fur collected. I suspect that over time there is a loss of performance so gradual that it's easy to not notice. I assume the new filters returned the vacuum power to it's original level of suction was a big factor. When I was browsing through all the available choices here on Amazon, a plastic "ring" kept appearing in many of the product images, however, people did not know what it is for or simply did not get one in their shipment. If you look at the photos I've attached one can see that I did indeed get one and figured out its purpose, to remove fur and/or hair from the horizontal brush. The bottom line is that I would definitely buy this item again. =========== EDIT, four weeks later: Since replacing the main roller brush with the one included with this product, I have experienced several “Roller brush is stuck” shutdowns and alerts. In each case, there has been nothing tangled in the brush and the brush was free to spin. I have to say it’s quite annoying to come home expecting the floor to be cleaned but only to find this error long before the job was finished. Today it gave this error twice in one cleaning cycle. I never experienced this problem with the OEM roller brush.

Euphy works good as new!
Style: 19 Pack
As soon as I opened the package everything looked the same- pre-filters, filters, main brush, and side brushes. I changed the big brush first;the only issue was the new brush body didn't have the white arrows to help aligning but that didn't affect how the brush worked. I changed filter and pre-filter, and finally the side brushes. When I turned on my "Goophy" and tried to let her run the side brushes were a little too (Goophy's side brushes sounded a little louder). I trimmed the side brushes a little and all was well. Goophy didn't want to run herself but it didn't take long for me to figure out it wasn't the new brushes ;just the operator pushing the wrong button. My Goophy Euphy did what she was supposed to do- vacuum the carpet and tile floor. Goophy Euphy still wanted to take the long way to her charging station which was nothing new and easily corrected. Over all the new brushes and filter restored Goophy Euphy back to when we first used her!

Don't be cheap like me - buy these and save yourself the hassle!
Style: 19 Pack
I made the mistake of going with another, slightly cheaper set of replacement parts for our Eufy RoboVac 11S. I did not heed the cautionary tales which lead me having to find replacement parts for the replacement parts. This brand fits our vacuum perfectly - the corner brushes don't pop off, the filter is the right size and the roller brush gets sufficiently tangled with cat hair so clearly also a good fit. My only concern (and why I only gave four stars) is - surprise! - the corner brushes. Do they stay on? YES! In fact, they is so secure, I had difficulty swapping one out. Here's the peculiarity of the brand - the "whiskers" on the spinner fell out. I found them all over the floor, on different surface types and under various conditions; they were not getting caught on any one thing. Not all at once, but over two or three uses, one of the corner brushes had become devoid of almost two entire spokes! Ironically, the little guy can't seem to pick up his own mess but I digress. Without the whiskers to grasp, removing the part was difficult. I ended up using a small flathead screwdriver for leverage to pop it off. While the other corner brush appeared to have shed some whiskers as well, it was not in need of replacement. Despite the shedding, this will be my first go-to for replacement parts next go round.
