Just what I was looking for.

By Steve Tarren

from Florence, KY

Comments about Digitech RP155 Guitar Multi Effects Pedal:

I bought this effects unit about a month ago and I'm very happy with it. I also use a Boss ME-25 which is a good processor too, but I want something with a drummer machine built in that would not break the bank and at the same time since I have a unit with an expression pedal I didn't need something extra that costed more. After using this I hate to say it, but the distortion sounds 200% better than my Boss and the noice gate on this thing blows away the Boss unit. What I plan on doing is running those two processors together because that way I have all the sound I want and need. The best part I love about this unit is it is 1000 times more tweakable than the Boss with the software you can download for free from Digitech and there are a lot of websites that offer a lot of free user patches for this unit. Great job.

nice little box

By Bob England

from Hesperia CA

Comments about Digitech RP155 Guitar Multi Effects Pedal:

Awesome learning/composing tool! Drum tracks are very rich sounding and the looper is just amazing! Purchased online and the ad still says there is an aux 1/8 input...bupkis. Still the best under 100 bucks ever spent.

Best Value

By Art

from Seattle, Washington

Comments about Digitech RP155 Guitar Multi Effects Pedal:

This unit is great! I had a Fender Dec 30 and I replaced it with this. Better effects and cleaner sound. Buy one of these and an amp and you've got it all!

Comments about Digitech RP155 Guitar Multi Effects Pedal:

This is an amazing pedal. It gives really great sounds, and tons of ways to make new, custom sounds. The effects and all are rally nice, and it's not that hard to figure out; it just takes a little time. Definitely recommend it.

Great Practice Tool

By Jamie

from Omaha, NE

Comments about Digitech RP155 Guitar Multi Effects Pedal:

This product is awesome!! It has everything you need in a pedal. The features are a little difficult to navigate at first but eventually it becomes a breeze. The looper is great for practicing riffs, scales, and soloing.

By caleb

from cincinnati, Ohio

Comments about Digitech RP155 Guitar Multi Effects Pedal:

Very Thorough, It has a large spectrum of effect with a really good tone. It has 30 tones to choose from as a quick start frame such as a metal scoop, a solo sound, A rock feel, A country tone,Blues, British, American, smooth. Or you can go into the main editor and choose from hundreds of sounds and effects. Very good pedal, durable also.

This is awesome

By Brock

from Crescent City, Florida

Comments about Digitech RP155 Guitar Multi Effects Pedal:

This little guy packs a huge punch. I bought this a year ago while being bored on vacation and needing some shred action, and I was pleasantly surprised with how good this sounded going through my dad's terrible, broken bass amp (haha) even. I got home and put it in my home studio however, and I was a bit disappointed. Recording to computer is highly inadvisable, because it really doesn't come close to matching other brands, line 6's toneport series in terms of quality... plus those are a lot cheaper. I'd say if you're looking to shred and crank your amp up to 11... get this now, cause it sounds awesome. If you want to do some serious (although budget) recording on your computer, get yourself a toneport with pod farm.

Awesome Pedal!

By Jacob L.

from El Paso, TX

Comments about Digitech RP155 Guitar Multi Effects Pedal:

This pedal is great, with nice clean and distortion sounds. As hard as this is to believe, I managed to get this pedal to sound like Gilmour!!! Added to that is a nice user interface, good effects, and USB recording. This is a great bargain for what its priced at. I would recommed this to any guitar player!

Great Pedal, Great Price

By Matthew

from Ivins, UT

Comments about Digitech RP155 Guitar Multi Effects Pedal:

I bought this pedal a while ago, and I still love it! It can get great effects, tones, cabinets, etc. With a wide selection of effects, this pedal will not let you down! It is easy to use, and comes with 100 presets that are great! Creating your own effects is simple once you get the hang of it. The drum machine is a little, 'eh' but overall, it's great for a pedal, and great for the price! I highly recomend this!

Great pedal

By Rick

from Huntington Beach, CA

Comments about Digitech RP155 Guitar Multi Effects Pedal:

This is my first pedal. I went back and forth between many models and mfgs. I selected this pedal because of cost, quality, and number of effects. I haven't been let down. It works great; better than expected. I love working with it on the computer as well. Fun and effective.
