What They Say

Just like the real vintage amps, I can crank UAFX Amp Emulators for drive, and use my guitar’s volume control for sparkling, three-dimensional clean tones. I put all three on my studio board!

    Fantastic!!

    I’m probably more interested with what I can do with my pedal that I’d struggle to do with the real amp , than trying to compare the two.

    I love distortion and maxing out this pedal gives me knarly / fuzzy gain at any volume.

    Played this with my laney frfr cab and direct ,and both excellent .

    I now have what I’ve always wanted , my sound at home , studio and gigs .

    Choose a pick up position and roll off the tone knob and instantly sold my fuzz .

    It’s a brilliant pedal and I love it .

    I have a pedaltrain nano with the del-verb , lion , Woodrow and a tc standard size tuner .

    I have a tele and a sg and the tones I can achieve seem endless …

    I haven’t felt the need to delve into the app and truthfully the appeal of this pedal for me is its analog feel , as I don’t enjoy editing on any level .

    I’m totally sold on these pedals and will definitely get more.

    Talking about sold , since setting up my board , along with fuzz I no longer need boost , overdrive or distortion pedals .

    Fantastic !!

    Seriously fantastic amp

    After recently purchasing OX Stomp - which is proving to be indispensable - I was very curious to try one of the 4 UAD Instrument Amps. I liked the sounds I heard in the demos, and Woodrow '55 - although perhaps not the most popular - had a particular appeal.

    Doing some background reading, I was prepared to learn how to coax the best from this pedal. I wanted something that could produce an interesting range of overdrives and fuzz sounds, but also be a solid clean platform for my other pedals.

    In the first few days of owning Woodrow, I spent mere minutes studying the manual, half an hour finding some go-to sounds, and hours (many hours) playing, recording and writing.

    How it should be.

    The clarity and warmth of the cleans is spectacular. This thing is alive, responsive, rewarding. I hear notes within chords chiming with separation and dimension. That opens up a lot of possibilities.

    Running the unit into OX Stomp adds another dimension, although the stock cabinets are excellent.

    With its dual gains - one a bit more aggressive than the other - and with the 3 flavours of boost, you can cover everything from arpeggiated jazz voicings, to blues, rock and beyond.

    Woodrow *feels* great to play, monitoring through a decent studio system. It highlights the tonal differences between my guitars in a way that other systems don't. Even the best plugins, for instance, tend to make all my guitars sound more like the plugin itself; they imprint their sonic signature a…

    Nice sounds, terrible blutooth app

    Always problem to connect. I can not understand how UA accepts this on such expensive pro pedals

    Nice Pedal But Terrible Bluetooth Connectivity

    The pedal is excellent as far as the sound, flexibility, and options. It lives up to the hype. If you aren’t depending on the Bluetooth connectivity to change presets then you should definitely buy this pedal. It sounds great.

    On the other hand the Bluetooth connectivity is a complete disaster. I have lost count of how much time I have spent trying to get it to work. I have attempted to connect on an IPad, Android phone, IPhone, and even going to a family property miles away from any other house to see if the problem was interference (as tech support suggested). All my other Bluetooth gear works without a problem so I know the issue is with the pedal.

    The truly odd thing is that every now and then it will connect for a few minutes at a time. Very frustrating and surprising from Universal Audio engineers . They usually know what they are doing and turn out superior products.

    A quick web search reveals that I am not the only one that has experienced the Bluetooth issues. Too bad, it would easily rate five stars otherwise.

    Really sounds great, but takes a little work

    This is the best "amp in a box" I've ever played. It just feels and sounds natural and fun. It has a huge range of sounds, like a tweed deluxe, but it's not obvious how to dial it in. It's not a straight emulation of tweed deluxe, because it's "always jumpered," which mean it doesn't model the interactivity of the controls the actual amp has without jumpering. I don't actually understand why it has three "preamps" that have adjustable boost's. One is to imitate Edge from U2, I guess, great, but it's already got plenty of grind

    It's not obvious how to get a good sound out of it: it take's a little work. But man does it sound great when you find your sweet spots. I love this pedal.

    IMHO the presets are a waste of time. there's no indicator of what preset you're using, and the software includes a bunch of other people's presets but unless you are using your phone onstage there's no way to tell what preset you've cycled to. I would rather have seen something like a jumpered/not jumpered switch, to make it more like the actual amp. The "room" knob sounds great below about ten o'clock: over that I have a hard time seeing why I would use it rather than setting up a short reverb or delay in the daw.

    So some criticisms, but overall it sounds fantastic and it's really fun
