Sound — 10
I currently am using a Line 6 30 Watt Spider III Amp, with a Epiphone Les Paul Remake which isn't a good setup at all, I've used a Fender Telecaster through both though and it sounds incredible, The DD7 can change the sound of anything and improve it. You could sing through it if you wanted. You can get a very good Coheed And Cambria or Pink Floyd Sound out of this pedal.
Overall Impression — 10
I play- Worship, Blues, Alternative, Jazz, and Hardcore. it's good for all of the above. I've been playing for 5 years now, The Boss Pedals I own consist of: DD-7, Super Overdrive, Mega Distortion, Compression Sustain2, Blues Driver, and Tremolo, I also use a Lyon Wah pedal, about to replace it with the Boss Wah/Distortion Pedal. Definitely play with the extra effects that the DD3 doesn't have before you buy this you may not need the DD7. The DD3 is also a great pedal. If this pedal was stolen from me I would just go buy it again. I love everything about it, and Hate Nothing about it(except for maybe the price tag) my favorite feature would be the analog delay it has on it. I compared it with the Line6 Delay and The Boss DD3- I chose the DD7 because it had The Analog Delay, Modulater, And Reverse, And A Longer Loop than the DD3, I Didn't get the Line 6 Delay because of it's hard to use stage presence it has. I can use it for recording and stuff but for on stage the DD7 owns the house. it's pretty "Boss" Haha.
Reliability & Durability — 10
I depend on it. I use a power supply with it. I have never taken a back up for this pedal, I would never replace it either. it's so amazing. It's my best pedal on my board hands down. It goes good with a compression sustainer, and a tremolo or phaser, and I usually use my blues driver and super Overdrive with it.
Ease of Use — 9
If you want to be able to change your sound on stage in the blink of an eye this is the pedal. It's definitely easier to use then the other delay pedals I've used. Everyone says that the new Line 6 delay is the best on the market, well I think the dd-7 is way better for stage performance. The only thing I don't like is the price on it. But it's a small price to pay for the sound it puts out.
