Housed in a sturdy 16 gauge steel housing that measures a mere 4" x 5.75”, the MDV-1 is small enough to fit on the most cluttered pedalboard, and because of the MDV-1’s unique voltage doubling circuit, you can use any standard “negative to center pin” regulated 9 volt DC power supply offering 100ma or more. Fulltone’s FPS-1 adapter is included for any US/Canada purchase. Inside, the MDV-1’s power is ramped up to the original Univibe's 18+ volts for high-headroom and BIG sound.
The new MDV-1 is not only beautiful, the price has dropped from $249 MSRP to $219… putting the street price way below $190! $190 for a hand-made in the USA piece of art.
Lately everybody’s talking about the Fulltone Custom Shop MDV-3… "the King of the vibes!" is what they are saying. But very few know that the MDV-1 and the MDV-3 are the same now, except for the MDV-3’s built-in foot-operable speed control treadle. Identical PCB, photocells, NOS 2SC828 transistors, and sound.
I bought a cream MDV and I'm out of luck, aren’t I?
Not necessarily, all Cream colored MDV’s made from August, 2013 on with serial# 9167 and higher are the same as the new MDV-1 and the same as the MDV-3.
What are these Photocells I hear about?
There are 4 photo-resistors in every real Univibe clone. If they’re not there, it’s nothing but a glorified MXR-type phase pedal with altered cap values. I spent a lot of money a few years ago working with John Greene (my Electronic Engineer) to blueprint the resistance characteristics as well as the rise/fall times of the original ShinEi Univibe photocell... to pin point the mojo of the old Univibe cells!
I thought you always had great photocells? What changed?
A new international directive aimed at reducing things deemed harmful to the planet called ROHS, that’s what. And those old Univibe photocells are most definitely not ROHS approved… they contain high levels of cadmium! By the the mid-2000’s you could no longer legally ship a device containing these type of photocells to most countries, so vibe makers (the ones with ears anyway) soon discovered their vibes weren’t sounding like they used to. Only I did something about it.
What did you do Mike? I’m half-fascinated that a grown man would get so obsessed about a silly 45 year old pedal design.
I worked for over a year with a prominent Photocell manufacturer, developing proprietary new photocells that respond the same way old cdS cells did. See, all the off-the-shelf photocells have a super-quick 25-75 millisecond fall time. They sound boring, and one dimensional.
I’ve tried your vibes over the years, why do the new MDV-1 and MDV-3 sound so huge and thick?
Partly because of the newer cells, and partly because I fiddle with things sometimes, and at some point a long time ago, I changed some of the values in the Deja’Vibes. But one day was playing a particular great sounding original Univibe (I have 8 of them) and was inspired to sit down and take some notes on values and finally yank out and sacrifice its photocells so that YOU could have a superior vibe! I also changed all values back to the original Univibe because people want that sound, not my take on that sound. A funny side note: the widely available Univibe schematic, the actual one included with original Univibes that was scanned and you can get by Googling univibe schematic is wrong. There's a crucial error in a key part of the circuit. I checked it against 13 original Univibes. My point? There's more to it than a schematic, you have to look, listen, and probe.
What does someone who knows ‘vibes (Robin Trower) say about his totally stock off-the-shelf DejáVibe?
"Simply Brilliant. I use it all the time. It's the best of its kind!!"
