Sound — 9
I plug my Squier Afinnity Strat into this unit and I plug headphone into the unit. The unit is not noisy, unless you use a high gain amp like a jcm 800 and use a DigiTech Death Metal stompbox with it. The effects in this unit are amazing, and every single one of them sound great. I have not tried to get the sound of my favorite artist yet (kutless), but I'm sure I will be able to. The distortions on the unit are pretty good, and they are better than I expected, but they are probably not as good as individual stompboxes, but they still sound good for a mfx unit.
Overall Impression — 10
I play all sorts of different styles of music and this unit fills all of them very well. I have been playing for 4 years and I the only other gear I own is my Strat and my Cube 15X. If this was somehow stolen, I would defanatly buy this again. I love almost everything about this unit, especially the effects and the expression pedal. I don't really hate anything about the RP355. My favorite feature has to be the expression pedal (I don't know if that's a feature, but oh well). I compared this to many other mfx units, like the Boss ME-25, the Zoom G21NU, the Line 6 Pod 2.0, the Vox Tonelab ST, the Behringer V-AMP 3, the Line 6 Floor POD, and a few others. I wish it had a slicer effect, now that would be cool. All in all, the DigiTech RP355 is an amazing unit for the price you pay, and if you're in the market for a mfx unit that's under $200, you should defanatly get the DigiTech RP355. Trust me. You won't be dissapointed.
Reliability & Durability — 10
The RP355 is "built like a tank" and is very sturdy. I would defenatly use this in a gig without a backup.
Ease of Use — 10
It is very easy to get a great sound out of the DigiTech RP355. To edit or make your own patch, you basically have 12 different amps and effects sections to choose from. First, you can choose an amp model out of the 34 different amp models which range from clean to heavy. Next, you choose a cabnet option out of the 18 cabnet models. After you choose your cabinet, you can choose to have a distortion stompbox out of the 18 that you can choose from. Next, you can choose to have an effect like flanger or chorus. After that, you can add a compressor. Next, you can add many different types of reverb. You can also add a delay. You can also choose what the expression pedal does. It can be used as a Wah pedal, a volume pedal (which is what the expression pedal defaults as), and many other parameters. You can add a noise gate, and you can even use the pickup simulator, which means you can go from single coil to humbucker pickups, or vice versa. Of course it comes with 70 presets right out of the box, with which you can find some sounds you like. The manual is very helpful. It tells you everything you need to know. It also comes with a 20 second looper and a drum Machine with 60 built in patterns. It also comes with a feature called Learn a Lick. What Learn a Lick does, it basically slows down 10 seconds of a solo on your favorite song, so you can learn it easier.
