    Excellent Effects

    I have dozens of effects processors, pedals, etc. and I can only say: If I'd known earlier what this thing does, I would have bought it much sooner.

    First, it comes with a "next step" style CV / exp pedal. Very different from traditional pedals but it has a fantastic unique action.

    Remember on HOG2 that expression pedal can do any of the following:

    *Bend / whammy (whole step or octave)


    *Sustain / gliss

    *Wah / filter

    And all these effects are top notch-- the wah & filter hold their own against the MF-101, Sonuus Wahoo and Cry Babies.

    Considering it also has sync and editability via midi (so cool to send LFOs to the different harmonics), it's a full-on studio tool. Sounds great on synths and percussion as well as the obvious guitar and bass uses. Getting up the guts to try it on vox. . . ;-)

    Seriously great piece of gear-- get it.

    Amazing pedal. Compared to the Micro Pog and Pog 2, the attack is much smoother, and it blends super nicely.

    Buy it before you buy anything else

    The first day I spent messing around with the HOG2 was greeted with disappointment. I was completely unable to find any settings that seemed interesting. I got more familiar with it the second day, and things took a far more positive turn. As I probed for some settings to store on the foot controller, I found all sorts of interesting sounds, from flute to xylophone to synth. Although it probably isn’t a true synthesizer from an engineering standpoint - I doubt there are any oscillators in it, for instance. Nevertheless, from a player’s point of view, the HOG2 adds selected harmonics, controls the envelope, and filters the output, and therefore should be considered a synthesizer in every functional standpoint that matters.
    The price of the HOG2 may make some reluctant, but, given the degree to which it functions as a synthesizer, one is getting off cheap in comparison to a Roland guitar synth. The only cheaper route for guitar synthesis is a Line 6 FM4, but those are monophonic with occasionally questionable pitch-recognition. The HOG2 is fully polyphonic with exceptional clarity for each note strummed. I really enjoy playing chords with my flute sounds, for instance. Whatever process of digital modulation the HOG2 uses, there is no detectable lag time between playing notes and hearing notes and glitchy warbles simply do not occur.
    The HOG2 can add parallel notes in harmonizer-like fashion, as one so desires. Alternatively, I have no idea what a “spectral gate” is, but when it’s on, it combines together all the notes into a single more complex timbre with added harmonics and overtones (something I’ve fiddled with on my own with combinations of harmonizers and ring modulators). The HOG2 is a culmination of everything Electro-Harmonix has learned from its own Superego, Micro Synth, and POG2. But the composite has its own unique character, and should not be thought of as simply a multi-effect. The Micro Synth remains interesting for its more dramatic filter sweep, and the POG2, for whatever reason, still produces a better organ sound. Nevertheless, if a guitar player is looking to maximize their access to a wide range of timbres, the HOG2 is priority number one.
    The foot controller is absolutely essential for storing all the many favorite settings one will accumulate. My foot controller is actually filled up already with my hundred most favorite settings. The expression pedal is perhaps not as essential as the foot controller, but very desirable and very recommended all the same.

    unique and versatile pedal

    The range of harmonics that this pedal can generate is impressive. The ability to add the UN effected guitar into the mix adds a lot of possibility. The expression pedal included is something in its own right. Very sensative and adjustable. Although it is hard to keep in one spot as its not a hinged rocker like normal expression pedals. Instead its essentially a rockable brick that effects parameters via orientation sensors buoy into it. Pretty cool minus the sliding around. The plethora of different modulations the exp. Pedal can manipulate really create a lot of possibilities. Construction is nothing amazing. In my experience nobody builds heavy duty stuff anymore outside of Moog music.

    Paradigm destroying unit

    This is an unbelievably good pedal for sound shaping. Combining it with the Electro Harmonics 8-Step and MIDI clock sync is a REALLY good idea for exploring other sonic universes. Caution when combining with external effects, because this can cause you to call in sick to work ;-)
    Suggestions: Next version, expand the synthesizer options just a wee bit more.. Oscillator? Wave shape?
    Pros: Incredible tracking, wide variety of tones you can produce. Expression pedal included.
    Cons: External preset pedal (optional, but pretty much necessary) is way overpriced. Spectral gate, Exp. Mode and Exp. buttons feel loose and flimsy.

    What the what?

    (Disclaimer): This is a first impression review as I've only just taken this thing out of the box within the last few hours.

    If I were basing this review strictly on performance the HOG2 would get a 5 star rating. This thing is ridiculous. It is essentially an entire pedalboard within a single pedal and everything it does, it does well. It takes some time getting used to the controls and how they react with one another, but once you become comfortable the sky is the limit. I mean this almost literally considering the capacity of the HOG2 to hit a full FOUR octaves above the input signal.

    The tracking is extremely tight, and the various filters and envelopes allow you to get some really robotic and spacey tones. As a starting off point I've had a lot of fun emulating the tones from the demos and then messing around with the sliders until i find something I really like.

    The expression pedal that comes with the pedal is pretty cool. It just rocks back and forth which is an interesting design and admittedly is taking some getting used to. I haven't had much of a chance to mess around with the range and bypass dials on the side. It seems like a much more controllable alternative to more traditional expression pedals and adds to the HOG2's already impressive amount of tonal options.

    My biggest gripe is that the midi foot switch for saving settings is not only not included, but costs an additional $60-80 depending on where you buy it. Sweetwater has it on sale for $62 which is better than I've seen anywhere else, but still, c'mon EHX, I've already paid half a grand for this thing. It reminds me of modern day video games where you pay $60 upfront for the game, but if you want all of the levels, characters, or in some cases the ENDING available you have to pay an additional fee. Other than this small complaint the pedal is awesome.

    Most satisfying was the actual purchasing process from Sweetwater. I ordered the product on Sunday, and with free shipping it was on my doorstep Wednesday morning. My sales rep also called me the morning after my order to personally confirm that I made the order, and also to verify all of the shipping information so that nothing unfortunate happened with the delivery. This was an unnecessary but greatly appreciated gesture, and made me feel that the staff at Sweetwater truly cares about the customer being satisfied with their purchase. When my HOG2 came, they also gave me some free candy which was just the icing on the cake for me.

    In conclusion, awesome product, awesome service from Sweetwater, include the midi controller EHX ...c'mon.
