I'll say this now, because before buying, I watched a Youtube Review where three Swedish shredders make this amp sound absolutely terrible. THIS IS A CLASSIC BLUES ROCK AND SOUL AMP. That's what I play (with a slide, for over 50 years), and I am very happy I bought this device between the time its price was slashed by nearly half and the day when they will surely sell out. IMHO, it's probably the best lightweight combo amp for sound and features since Vox stopped making the Pathfinder 15R, which I also own -- and one of the very few devices I ever bought new. BTW, I looked at it because the best amp model for what I do on Zoom's MFX pedals is the Marshall Bluesbreaker. I never owned a Marshall before -- I don't like the sound of their solid state amps, and the tube amps are too heavy and powerful for me. I sure liked that sound, though. Then I spotted the Origin, and finally found a YouTube clip of a guy playing a Tele through it that confirmed it would do what I wanted it to do.
For someone who plays small rooms, the 5 watts on this amp are plenty. My ears were recently damaged by playing a gig with two guys who each used 150 watts of amplification to hammer 30 people sitting about 20 feet away. That's when I started looking for a 5W tube combo (after quitting the band), and the feature set on this one impressed me. You need to crank a tube amp to get the best sound, which means my 15 watt Fender SCXD is too powerful for practice and small rooms. (Why I didn't want a Blues Junior, LOL.) The SCXD has decent onboard effects, which I use. The Origin 5C has none, but it also has a silent FX loop, and a cheap Zoom MS50G (another best buy) sounds lush through it. I haven't tried using the FX send as a line out yet, and I see no reason why it wouldn't work as it does with plenty of other amps. I did take off half a point for the feature set because I like having a line out (as do my other amps).
It took me half an hour to find sounds I really, really like on this amp, and every time I turn it on (several times a day), I find more. I don't own a Tele, and I can get a Steve Cropper sound from the Origin. I can also get a warm jazz sound and everything in between -- despite cutting the bass below noon most of the time. It works for AC/DC too.
It's not perfect. The 8" speaker can get flubby with the boost on, and I like to leave it on for the breakup and edge. I have the same problem when I raise the volume past two o'clock. Maybe that will fix itself when the speaker breaks in. (Update: it did.) I won't change speakers, though; I really like the range on this one, including the bass. The "tilt" switch tightens and brightens the sound, and in any case I usually don't need all the volume this device can put out. (In fact, I really like the 0.5 watt setting for quiet practice or learning tunes.) If I need a bigger amp, well, I'll use one. When I need more gain (and better control over it), I'll put an OD pedal in front of it. In a week of playing the amp about 2-3 hours every day, I haven't needed it. That's saying something, because OD is essential to most slide tunes (ask any Elmore fan).
I could go on and on, but I'll get to the point. This amp is better designed, with well thought-out features that actually work, than the vintage 5 watters that guitar players salivate over. I don't need or want it to be louder than it is. It's absolutely noiseless, very easy to carry, and comes with a footswitch for boost and FX, which makes a sweet deal sweeter. It captures the sound of my guitars and adds something special. The only uncertainty is whether it's built to last, and that's why I bought it new, to get the Thomann guarantee. At the price Thomann is currently selling it, it's a no-brainer for anyone who plays small rooms and classic styles. If Marshall ever stops making it, and the quality is real, I predict it's gonna become a collector amp like the Pathfinder 15R. If you need an amp like the one I just described, it's a very safe investment. I'm a cheap and frugal gear guy, and I have no buyer's regret whatsoever. Play on!
