Near mint condition, amazing sound, smooth operation.
100% original, made in Japan with original MN3205 BBD, all trims finely tuned to factory values.
Thank you for your interest, please read on.

Description:
Not too bright not too dark, not too grainy not too filtered/aliased, my favourite characteristic is that it doesn't oscillates infinitely into chaos (as long as time is longer than >180/200 ms). It will oscilate like crazy with shorter times and max repeats, like all BBD delays (that I know of).
it's oscilation is like a veeery long trail of superbly calibrated ambient BBD goodness that never gets out of control but slowly and gently fades away like angels going back to heaven. The trails volume doesn't spike like crazy at longer times, so no one's life is compromised with these settings. Be it a simple slapback or a long ambient droner, this fine delay does it all with simple grace. Forget about that +400€ delay with 50 page manual... Trust me, these 3 knobs have got you covered, play more, tweak less. This is an underrated gem of a pedal.

Please remember for external powering this is designed to work with a 12V ACA power supply, not your standard 9V PSA. I read that it still works fine with your standard 9V PSA but the LED wont light on. I always used 9V battery on my analog pedals, this one only draws 15ma making it one of the most economical out there. Strong and clear buffer that doesn't interfere with the dynamic interaction between amp and the guitars volume knob. It's also super quiet, more than most modern analog delays.

There's a sweet spot around 14 pm on the repeat rate that if you max the intesity (repeats) it only starts oscilating if you stop playing, if you play anything while on the verge of oscilation it somehow prevents that crazy build up of delay. Very musical indeed.

Expensive vs Valuable :
Besides the mint looks and the guarantee that it's 100% original, this unit was accurately calibrated to factory values by professionals using dedicated electronic equipment like fancy oscilloscopes and multimeters. This is the only way to ensure the unit sounds its best and behaves as it was designed to (like that small but intentional and super musical detail of oscilating only when you stop playing). This guarantee I give you adds up to it's value/price. Considering the many depreciative and inaccurate (I can assure you) reviews out there I believe that many idiot DM3 owners messed around its internal trims "to make it sound more like DM2", and then hundreds of uncalibrated DM3 flood the market because no one can make it sound good again. Then some unknown hipster buys it and rates it 1 star claiming Boss engineers know dogshit... But you know better, right? :) Correctly trimming these pots is nearly impossible to do just by visual clues and a good ear, as they are extremely sensitive and interact with one another. Then I get messages saying my pedal is expensive and I'm a fool, lol.
My pedal is not expensive, it's a beautifully mint time machine apparatus that was expertly calibrated to historical factory values by the nerdiest caste of old school audio engineers. If you want a good DM3 like this go ahead and buy the cheapest one you can find, then spend +150€ + shipping sending it to a reputated specialty store to have them calibrate and mantain the unit. You'll end up with a 360€ scratched up but great sounding DM3. Mine is mint, and still cheaper.

But some unkown hipster rated it 1 star:
That unkown hipster had a unit which was either faulty or had it's internals "recalibrated" by some experimental idiot. Or maybe he's just fool. "Carbon Copy sounds better?" "noise gate choking blabla?"
This unknown hipster clearly went for the 50$ DM3 he found at his local flea market under some rusty used car radiators and exhaust pipes.
The fools who depreciate the DM3 either do it because they bought a faulty/uncalibrated unit or just need to justify why they spent +500€ on a Memory Man or MIJ DM2 or whatever. Anyone who claims this is a bad delay pedal is either blatantly lying to validate his feelings or simply knows jackshit about pedals and electronics. Trust me, I had very expensive analog and digital delays. This is a fine delay with a great buffer, dead silent operation, simple design yet versatile settings, low power consuming, and my personal favourite - another unknown hipster who earns 0€ with his musical hobby yet his previous delay was a Chase Bliss Audio Tonal Recall, a horrible pedal that sucked all my tone if I unplugged it's power source... :)

Why sell this gem? : I stopped playing electric about a year ago and sold everything, this was the only pedal I kept to use as very expensive paperweight. I've been exclusively playing acoustic unplugged with mics, no need for pedals. It's been sitting on the desk now for more than a year, and I need to do expensive setup to my acoustic, so I decided to give you a chance to fund my musical needs by paying my luthier, getting in exchange this very loved and esteemed +40 year old Boss DM3.

Will be promptly shipped with love via UPS.
