Eventide H-3000 upgrade

by | Mar 5, 2014 | News | 0 comments

You may have seen on our Facebook page that I recently managed to get my grubby hands on an Eventide H-3000. “A what?” I hear you cry…

The Eventide H-3000 is what’s known as a Harmonizer – a unit capable of effects like flanging, phasing and chorus by splitting the incoming signal and applying varying degrees of detune and delay to create a thickened sound. The units is synonymous with the wide 80’s guitar sounds from Eddie van Halen and many, many others and that sound is making a comeback…..

In fact my most popular videos on YouTube (over 60,000 views and counting!) is a tutorial on how to create a split harmonizer effect using software. You can see it here: 

The unit I have is the original from 1988 and has seen various upgrades in the past two decades – the problem being that the upgrades are usually on the rather expensive side – the newest model – the H-8000, retails for around £4,500……

The is where eBay comes in.

For around $60 and a two-week wait you can get hold of the upgrade chips to convert your unit into one of its newer siblings in all but the name. The units all contain the same algorithms – it’s just the presets that change.

Here you can see what the H-3000 looks like on the inside – pretty daunting! the area for modification is in the top right near the power switch. A PCB trace needs cutting and the ePROM chips needs swapping over – made a lot easier by removing the IEC power inlet and moving it to one side for the duration.

The upgrade itself was fairly straightforward – a trace on the PCB needed to be cut by a razor blade and then a new connection needed to be made by scratching the trace off a couple of pads and producing a bridge between the two via a blob of solder. So far so easy (although making my own compressor certainly increased my confidence!)

IMG_0527Here you can see the new ePROM chips (in white) and you can just make out the new solder bridge made to change the PCB configuration.

Once the PCB has been altered it’s simply a case of prising out the old ePROMs and replacing them with the upgraded versions which contain the new OS and data, including all 753 lovely new presets! I had to bend the legs of the ePROMs slightly to get the seated properly which was just a case of bending them together on a flat surface and then they snapped into place.

The last thing to do was to reset the operating system by holding the Function button during power up and Voila! An upgraded and vastly more powerful H-3000 without breaking the bank!

Adrian, thank you for a great day and a half of recording finishing last Wednesday. Having been together as a group back in the 60s and now getting together 50 years on to record was a bit nerve racking but you made the thing so much easier with your professional advice and guidance. You've got a great set up and since we had Rog playing flute and drums [for some reason not at the same time!] the layering down of the instruments went really well. We had a great time and ended up with a CD and lots of happy memories. Martin living in France doesn't make it easy but we have all vowed to be back with something completely different for you to cut to disc. Thanks again and see you soon. Sam, Andy, Roger and Martin of Old Lemons fame.

Having recorded at Threecircles several times, there's good reason why I keep going back... with such high end equipment, Ade's expertise and competitive pricing there's no need to go anywhere else!!

I first met Ade when a charity band event needed a sound technician and PA rig at short notice, he provided top notch sound for the event and also offered a very well priced live recording, which he would go away and mix at Threecircles Studio. The results were brilliant, I have never heard myself recorded live so well and the mixing was fantastic too. As a result, one of my bands then used Threecircles services again, this time at the studio to record a track for promotional purposes. We had a great time and were really happy with the results! Would highly recommend for both studio work and live sound.

Ade at 3C is a true hero. Aside from having professional equipment, incredible understanding and knowledge of music production and a brilliant studio - he is a real genuine man. If I could I'd give this studio 6*, Ade recently recorded a single for my band completely for free because he knew we were doing it for charity.
