Boss DD-20 Digital Delay

It has relatively a lot of different types of delays and knobs. Takes quite a while to get the sound I want.

I'm not particular about delay effects like some geek that only wants a true tape echo for that effect. I think this pedal does an excellent job.

The Tape and Analog effects are very lush, warm an nice. I fall in love with them. If you let them self-oscillate, they just give you amazing tones.

I would like it if the Dual mode offer a longer delay time in the Short mode.

The Reverse is kinda hard to use. You have to get the right timing to get the nice delay sound.

The Modulate gives you a chorus sound in your delay and using the tone knob, you can get a lush and warm sound out of it.

This pedal gives you crazy effects too like Twist. You can totally get an out of control oscillating effect with this.

The Sound On Sound lets you record a loop and lets you play over it and even record over it. Great feature. I just wish they have longer recording time.

The Time knob gives you precise control over the tempo which is very cool.

Built like a tank. No worries using it live without a backup.

Never dealt

This is a very good pedal that gives you tonnes of tones. Of course don't be like those morons that bought this pedal and complain that the different types of delays don't sound like the originals. DUH! It's a modeling effect. It gives you a very close to original tone. If you want more, save up and get the originals. You can definitely get a very nice tone out of it. If stolen I would definitely get another one.

It pretty easy to use without any guidance, and the manual effectively explains anything that you can't figure out. If you're familiar at all with delay, this is easy to use.

I'm using this through a Fender Blues Jr., a Vox AC15, and a Peavey Ranger 212. I usually use a Strat, but I also use a Les Paul and a P-90 equipped SG.

All of the delay modes sound good. It even has a modulation mode that's pretty nice. I use this mostly just for echoes, but it'll do slapback (the tap-tempo footswitch is a great feature) and anything else you want out of a delay. It's also got a sound-on-sound mode where you can record up to 23 seconds, loop it, and practice your soloing. I only needed an echo box, but I chose the DD-20 due to that feature (I was going to buy a delay pedal and a Loop Station, but I figured I could save some money and get all I'll really use out of this one box).

Boss pedals are the best for reliability. I'll probably still be using this pedal when I'm a grandpa.

They're okay.

I've been playing for twelve years, and I'm very lucky to have a lot of nice gear. This is my only dedicated delay unit, and I expect it's the only one I'll ever buy. I like this pedal better than Line 6's comperable model. Everything sounds great, and it has very useable features. If you want delay, this is your box.

If you read the manual you will be getting great sounds in no time.
It may take a little while to figure out the more advanced versions of outputs and pedal assignments.

Sounds are great. What a pallet. I don't know if I would use a couple of the settings but even after owning it for a couple years I still can find new things.

Boss makes solid stuff. I've gigged out many times and never had a problem.

Never had to use them.

I play atmospheric folk as well as improvised experimental and I use this pedal all the time for looping as well as the dealys. It's great to be able to store settings and call them up on the fly. If my effects boxes were stolen, this would be the first to be replaced.

ok it is really easy to use, at the begining i found out pretty much all of the functions alone, but fot the modulate and maybe an other mode i had to look in the guide.

you have to be patien to find the right settings and for it to sound good and be timed but you get used to it quickly.

also the different modes as tap tempo, the different timings (doted eighth notes...) and everything are pretty easy to figure out

again, it is really easy to use but be patient...

i use a les paul and a roland cube 60 (with other boss pedals)

the tap tempo is useful for covering songs easily

SOS - record layers and layers of riffs

WARP - simply holds every note as long as you want

TWIST - makes the noise of a prison siren when pressed

TAPE - has one or two delays at the same tine (very cool for short delays)

ANALOG - very soft delay, very useful

STANDARD - as said, its standard

PAN - useless, you need two amps to play with it, or else it plays back normaly once then takes twice as much time to play back again

Dual - cool, you take your delay (1ms to 23 seconds) and you chose an other from 1ms to 100 ms with the first one

SMOOTH - reverb and delay at the same time

MODULATE - a delay with chorus (very very nice for acoustic)

REVERSE - cool but extremely hard to understand and play with it

delays sounds good with distortion and wah wahs. it is not noisy but put it first in your effects chain

You can get a lot of really really cool sounds is you have the time to turn knobs. turn, turn, turn and turn... besides that i think it gives more than needed for a delay pedal

9 because of reverse

i had it for less then a year... cant tell

i play metal (children of bodom, in flames, necrophagist, metallica, iron maiden etc) and it sounds good with everything, especially acoustic parts :P

i have been playing for 6 years, i have a a strat, a les paul, a classical guitar, im looking forward to get an acoustic one for jamming at camp fires :P i had a couple of marshall amps, begringers, and the cube 30, now i have the cube 60. i use the dd-20, the od-20(distortion/multi effects) and the pw-10 (wah wah, crazy wah wah and multi effects :P) id defenitavely buy it again is it broke or something, it really is the best delay pedal you could possibly find everywhere and for cheap (better then digitech ones)
it is good for improvising in every style, trust me =)

The functionality demands manual reading to exploit the modes available, it is well written and easy to follow though. There are only four writable patches. There are no USB or MIDI connections. I thought this strange considering it's a digital device offering so many FX permutations (This is reflected in the 7/10 score). This rules out any software interface too. It is graced with -20 and +4 dB output options. Sadly there is no facility for expression pedal parameter manipulation.

I use a Cornford Harlequin with a standard LP. Other FX inc Maxon OD9 and JD Wah. This is a very flexible pedal that manages to emulate differing delay effects these are
SOS - sound on sound looping
Twist - a one-trick up/down pitch saturation
Warp - Hold/Oscillation switch
Tape - a convincing copycat emulator, warm with soft decay
Analog - Based on the Boss DM-2, a clear delay with soft decay
Standard -
Dual - fast&slow delays in series
Pan -
Smooth -
Modulate - Mild chorusing can imitate echo-plex if correctly adjusted
Reverse - Not really convincing, delay times can create interesting textures however.
Not true-bypass, but no apparent colouration either. The pedal is quiet. I haven't tried it with anything else in the signal chain yet.
There are fine sounds to be had, if you have the time to read the manual and program for live use!

Only owned it for eight hours

No comment

I have been playing since the eighties. I moderately use overdrive and wah pedal when playing live. I was surprised how close the DD-20 came to emulating my old copycat, there again I haven't it since 1993 when I flogged it for a digital delay, oh well!
The pedal offers more than I'd ever use, still not 100% about have digital in my analog chain either.
Given time and attention unique and interesting effects wait to be discovered.

This pedal is very easy to use with reading the manual even just the once. Since it is a good combination of traditional functions and more modern features, even advanced features are relatively easy to use and it's easy to store and edit the four memory slots. To be honest, I haven't used the Tap function on the right pedal that much but this allows the user to tap in to correct the tempo easily for a specific song. It's easy to get started on this unit and stereo ins and outs make it even more versatile for really big space.

The sound quality of this unit is first class, well, mostly. The reverse effect is disappointing, I mean it reverses the sound for sure but makes an annoying click when set to produce only the reversed signal as it doesn't cut off the initial pick attack. Also disappointing is the "smooth" setting as it is basically supposed to be a delay/reverb combo but I feel that the effect lacks enough reverb to make any substantial difference from the standard digital delay which is also present on this unit. These two criticisms aside, the rest of the sounds available are just plain sexy and wonderful especially the accurate Analogue and Tape (you can even select between one and two tape heads on the Tape mode) which should please the most ardent Durutti Column and U2 fans (like myself) and then some. The unit has a useful delay effects including a Chorus/Delay, Dual (long and short delay for intersting variations on the slapback sound), Warp and Twist settings as well as Sound on Sound and the standard Digital Delay with great scope for the desired sound and the unit allows my pure signal to shine effortlessly in any mode. I play all sorts of music and have been able to find sounds that are appropriate to any song or style with a bit of care, if like me, you like a bit of ambient guitar, this is great.

Only had it for three months or so, no problems so far. The pedal feels well constructed.

I have been playing for around 10 years now and have found this pedal to be one of the best purchases that I've made. This is a great choice for live work or in the studio even as an outboard unit. Gigs and even jamming just isn't as much fun anymore without having this pedal in my board, i've got to like it that much. It's a perfect balance between more complicated rack mount units and older stomp boxes, just experiment with it and prepare a couple of presets before going to your gig and you cant go far wrong. I haven't any criticisms other than the reverse and smooth settings although for this price so much is already on offer that it isn't a big bone of contention.
