    Full and Rich Great Vocal Pre

    Recently tried this on a singer songwriter piano player a la Elton John, Billy Joel. Used a Miktek CV4 and included a light dusting of a Cranesong Falcon compressor. The mids were the star of this setup, thick full and rich working with the piano without any eq during tracking. The intimate parts of the songs were warm, very present, clear and emotional using proximity effect in a very musical way that my others pres could not replicate. The highs just seemed to be a natural extension of the mids blending in a natural way that added a wonderful color.
    I A/B'd this pre against a great river 500NV (which is one of my go to vocal pres) with the same setup and it seemed the highs were a little more pronounced on the GR which I felt I would have to eq to fit better with this singer,
    I was surprised at how well balanced the Heritage is and the type of mojo it had. I was looking for another what I would consider a "vocal" pre to add to my collection (API, Millenia, UA, newer NEVE) and this is certainly a keeper possibly being more of a go to now over my other favs. If it proves to be as good on other sources I may have to get another.

    I usually don't hear a lot of difference between mic pre's however I can really hear a lot more depth with this one the sound seems richer more dynamic , smooth. I have tried it on metal guitars with a 57, snare with a 421, and vocals with sm7b everything seems more in depth, Killer mic pre!

    Can't go wrong with a Heritage Audio 73 Jr

    Welp, I’ve finally gotten around to writing a review for this absolutely stellar preamp... it only took me three years! At least you know that I actually had time to give it some use before writing my review.

    Since, winning my 73Jr in an online writing contest, it has made valuable contributions to all of my recordings.

    Everything about the 73Jr is well made and I can't say enough about its build quality. It’s based on the vintage 1073 preamp and it adds a warm, creamy clarity to vocals and it makes digital keyboards/synthesizers sound less digital before hitting the DAW. My 73Jr does what it is meant to do and it does it flawlessly. BONUS: when pushed it adds some really sweet breakup to clean guitar.
    I never imagined that a mic preamp could actually contribute to a recording... I mean, all they do is raise the volume of a signal, right? Hahaha! I was wrong and I'm glad I was wrong!

    Had I not won my 73 Jr in a contest, I would have never found out how truly necessary a good preamp is to making a quality recording.
    I have to admit that, my first thought was to sell it for some quick cash - I didn't own a Lunch Box and my prize was going to require the purchase of a Series 500 chassis. But, ha! I'm a gear freak and the 73Jr now sits next to an harmonic exciter and a compressor.

    I'm glad I spent the money on a Lunch Box because the 73Jr is a keeper!!!!
    If you are in the market for a 500 Series preamp, the Heritage Audio 73Jr will make you a very happy camper.

    Its a truly special unit. Its a best in class considering its price, having a hpf, and line in onboard. Without all of those things it still wins, as its exactly what your looking for sound-wise. Ive tried several other sub 1k iterations of this circuit. Up until now, nothing has gotten me this close. Shines on vocals, and synths.

    Im frantically trying to save to get another unit, and will eventually add the eq's as well. This is the real deal folks.

    My Sweetwater Rep, Brian Loney was dead-on with this one!

    Incredible Classic Piece

    It's the real deal... been tracking vocals on this thing with an SM7b and Warm Audio 1176 after in the chain before printing in Protools... excellent. Just recently tracked a kick drum with it and it was surprising very transient and punchy accompanied with API 550A/560 EQ within the Protools DAW. Incredible piece that is a MUST in your U-rack.

    I'm completely loving this preamp after a couple of weeks of ownership. Dialing in a good sound is straightforward. I have gotten thickly saturated sounds from a DI improving tone on my Fender P bass and allowing the bass to be heard easily in a mix. Playback on my iPhone speakers still produced the clear sound of the bass recordings. With a cheap mic I was able to dial in a clean sound by keeping the input transformer subdued and cranking the squeaky clean output transformer. By the way, the pad is in the chain before the input transformer so engaged you can crank the input harder. Also lots of success with my Alpha Juno 2 analog synth. It sounds huge. I will likely invest in the 73eq down the line. Tone galore.

    Absolutely Gorgeous Sound

    Cant go wrong with this Pre. The amount of tonal variation the gain knob provides will make it easy to fit any source you throw at it. Great on Vocals - just sounds simply expensive. I usually record guitars direct and this thing gave my Axe Fx 2 a new life. ( Never thought the sound of the Axe fx needed any more but this preamp just gives the sound an extra level of clarity )

    Can't wait to get at least another one of these units for a stereo pair.

    Heritage Audio HA73jr

    The Heritage HA73jr is a great addition to the 500 lunchbox series!
    So far I've used a pair these to record stereo acoustic guitar with Royer 101's with very good results. Vocals and DI bass also sound great. I don't see how anyone would be disappointed with this mic pre. I hope to add a few more to my rack soon.

    Heritage Audio 73jr

    The 73jr is my first module for my new Lindell Audio 503 500 series chassis. Though I have used a wide variety of console pres, 18" rack pres, and desktop pres in professional environments, this is the first that I have used in my personal recording setup. Previously, I was using the Focusrite 2i2, and I am currently using an Apogee Duet. Switching to the Apogee was a huge step up; the converters are so much cleaner, the mic pres are smoother and more detailed, and they stack nicely. When I plugged the 73jr into the Apogee and bypassed the internal preamps on the interface, I was able to hear an immediate difference. I run the output knob all the way up, and adjust the input gain until I get proper recording levels, then I'll attenuate with the output knob if needed. It's so warm, and smooth, but has a detailed and sweet high end that makes the apogee sound dark and pillowy. The preamp seems to iron out any harsh frequencies, leaving me with a sound that I can just "drop" right into the mix. My first signal to run through it was distorted guitar; there is so much space around the instrument, as if it's picking up the sound of the speaker and the cabinet. As I push the input knob and roll back the output knob, the sound gets brighter and fatter at the same time. It also has this smear to the signal that is very pleasing to the ears. The 73 truly has a character of it's own. It's hard to explain, it just works better. A lot better. When you start to stack tracks through it, that's when it all comes together, and you sit back, and it just sounds huge. It sounds like a record.

    Great Addition!

    I've used 1073's in many studios however I've never owned one myself, until now. I really can't hear any significant difference from the HA73jr to a 1073. It's just that spot-on! Warm round bottom that adds some weight to the source. Great on vocals, drums, bass. Great purchase at a reasonable price point.

    Best Kept Secret

    I've owned and used nice preamps over the years , but this one is my favorite. It sounds exactly like the vintage 1073 modules I've used in the past . Can't wait to get more . My new favorite Bass Di - and just killer on vocals . Sounds like a record.

    No Carnhill / Not a 73

    Here's a very good pre, period. However after opening up this unit side by side with the usual competitors, BAE and AMS, it was clear that they do not use the same transformer. Simple as that.

    You don't have to take my word for it. Do it yourself and see with your own eyes. It does sound close to the 1073 but not enough to build an entire marketing campaign claiming to be using authentic components. It could easily be a 5 star pre but I'm taking 2 down for the lack of a REAL Carnhill transformer.
