Amazing bit of equipment - served me well :)

It was faulty. The audio I recorded was 'corrupted' according to the accompanying software. Each loop was reduced to about a tenth of a second. I heard that other people have had similar problems but I cannot verify that.Useless. I don't know if they are trying to do too much in one box but it simply didn't work and so went back after a couple of days.Ended up buying a Jamman Solo XT and adding it to my existing looper. Very happy with that.

Having played guitar for years but never really getting into pedals until recently, I wasn't sure if I would regret spending so much money on one. This pedal is simply amazing, I knew it was a good one after asking around and reading up on the ones in this price range and I don't regret my choice in the slightest.(I'll leave the more technical aspects to those that understand it better than me, for the average guitarist noodling in their room, it's perfect).

I bought this to use with my "couch guitar", meaning I wanted something for songwriting, practicing, noodling, etc. This is absolutely the perfect unit for that. One of the best features I've discovered after purchase is how cool and flexible the drum machine is. It's not programmable or anything, but it's very easy to upload your own loops (which can be anything, obviously - drums or no) via the SD card and then mess with tempo and mix. Note that the pitch of the loop does change with tempo, although what you loop on top does not. So if you want to mess around over a recording you did with the band last week, or try different iterations of a solo on a cover, you just dump the audio file onto the SD card in the right place and all of the sudden it's one of the drum tracks.The only negative review on Amazon for this mentions that it's not well-designed for live on-the-fly stage use. I'm not sure, but that reviewer may have found some benefit in the auxiliary "loop-up/loop-down" pedal, which would have allowed him to pretend that he was deleting a loop simply by moving on to the next blank "preset". But as a standalone pedal, I think he's probably right that it's a little too complicated for that application, and there are other products out there that are designed for live improv looping, etc.My only concern is the push-click "Mode" knob. It seems like the cheapest component on the unit, and will definitely get the most use. The knob cap feels like something from a mid-80's Crate amp, and I'll definitely be looking for something more sexy to replace it with. In fact, the whole "Mode" section is a little clunky, and I'll bet that the engineers at EHX wanted something like a mini LCD, only to be told -- nope, at this price it's LEDs and a delicate push-pot with a mid-80's crate knob. Anyway, if you want an LCD just turn on your laptop and open your DAW. Also, for not much more the 45000 looks like it turned some of the "Mode" functions into actual knobs and sliders - but alas, no drum machine - which is my favorite part!One other criticism, and I just discovered this last week when I brought this in to my daughter's school for family show-and-tell (recorded all the kids playing percussion, yelling their names, speeding up, slowing down - it was awesome.) The microphone input replaces the Left guitar input, and there's no summing at the outputs (even though the left output reads "mono"), so if you want to use a mic and a guitar at the same time, you might need something to sum them post output. Luckily my little lunchbox VOX amp that I brought to the school had two inputs -- otherwise I'd have been screwed. In front of my daughter and all her friends. That might deserve a one-star reduction, but nope -- I didn't read that part of the manual.Highly recommended awesome thing.

This pedal is amazing. I didn't want to have to buy another looper again, so I went with this one for all it's features. Mentally, I like the piece of mind of knowing I'm not limited on storage space. The built in drums loops are out of this world too. I've been playing for over 20 years and this looper has improved my playing exponentially. It's great being about to play rhythm and lead, change riffs, adjust tempo, and much more.On the other hand, I had spent a lot of time debating between this and the 720 and 360. In retrospect, I think both the 720 and 360 would have worked just as fine for me (sans the drum loops). The 22500 has a lot of features that I don't need right now, but I enjoy knowing they are there. So my advice is this: If you're not sure if you need this or a cheaper model, get the cheaper model.
