    Get the gain-drenched distortion you crave!

    The LPB 2ube is the velvety entranceway your instrument has been waiting for. As its name suggests, this line-level preamp uses 2 tubes to deliver optimum gain while remaining quiet and transparent. Offering amazing definition and warmth that you wouldn't expect to find in a footpedal, the LPB 2ube applies a full 300V to the tube plates so you get total performance and power without compromising your tone quality.

    In either stereo or dual mono mode, the LPB 2ube offers numerous applications. 2 warm and full frequency inputs and outputs, as well as the potential to gang the I/Os, make for a clean preamp stage with both master volume and master drive controls.

    I bought this after reading reviews about how it adds warmth to your sound. Well, let me tell you that this is absolutely true. If you run both sides in series, and experiment with the gain knobs, you WILL find a natural, even order harmonic distortion sound that you like. Maxing the right side and turning the left about a quarter of the way up will yield an ENTIRELY different sound than the vice versa setting will. It pays to spend an hour or two experimenting.I realize this is a preamp and not a distortion effect, but used as such this thing will SLAY a lot of the distortion pedals out there. It makes a run-of-the-mill solid state amp sound really awesome; you can tweak this thing to sound like anything, from crystalline bliss to satanic raunch. it makes a tube amp indescribable.By the way, I can't stand poseurs who try to sound sophisticated by using words like "warmth" and "shimmer", but damned if they don't fit the bill describing this product.Bottom line: If you have pretty good gear, but just can't seem to get your sound dialed in exactly like you want, run this in your rig (both channels in series-you need an extra patch cable). One more thing: if your guitars all sound the same through your current rig, something is wrong. Vacuum tube preamps allow a guitar's true individual character to shine through.Try it out, if you don't like it, return it. I bet you'll keep it! by the way, I am the first to admit EHX (like Gibson) is overpriced. But occasionally, you get what you pay for. This is one such case.

    I was looking for a way to send my guitar to two amps. This pedal can do that, but I find myself leaving it bypassed most of the time because, like the reviewer before me said, this thing become unmanageable pretty quickly. The first one that arrived had an extra hissy left channel, but Musician's Friend replaced it without incident. The second one, however, had an only slightly less hissy left channel. That "quiet and transparent" part of the description is using a bit of liberty. Linking the two channels together sounded cool on paper, but the volume and overdrive settings have a really narrow usable range of adjustment with it configured this way. That said, the right channel can be useful, but I still hear the tone suck in the left one when playing in stereo. So sometimes I have both amps connected but just roll the left channel back to 0 when on. In my opinion, stereo amplification with the preamps bypassed is this pedal's most useful setting.

    Outstanding pre-amp, absolute necessity

    By Mike Lindgren-JDVvJ

    from New York City

    Comments about Electro-Harmonix Classics LPB 2ube Stereo Tube Preamp Guitar Effects Pedal:

    The 2ube is a piece of gear that I now consider essential. I use it to split the signal from my guitar, sending one side through effects to a MesaBoogie 22+ and the other side clean to a Epiphone tube amp. It warms up the sound and adds outstanding harmonic richness and sparkle. Ganging the two in serial didn't work too well for me, but I have other pedals to provide boost. I turn it on and leave it on and it enhances the tone maginficently. It is a little on the noisy side but that's what you can expect.
    For the sound it supplies it is a bargain.

    Great for Acoustics to Mixer

    Comments about Electro-Harmonix Classics LPB 2ube Stereo Tube Preamp Guitar Effects Pedal:

    First, I'm using this pedal as a preamp between my Taylor T-5 Acoustic/Electric and my mixer with a passive direct box in between them. I've also used it to record my acoustic. It works really well for both of these applications, and does the job of a great tube preamp at a VERY reasonable price. The difference in tone is subtle; but the change in the feel of the note or chord that is picked or strummed is significant. Notes bloom the way you'd expect from a tube amp and compress naturally. The top end is less harsh; but clearer. The low end and note definition is well defined, especially from string to string while chording. This preamp will not make you say, "WOW" unless you understand how difficult it is to find a real tube preamp that runs at high plate voltage at anything close to this price point.I see a few reviewers that are using this as a boost in front of an electric guitar amp. This works; but I feel that there are many pedals that provide more flexible overdrive or boost. That said, I do still like it for this use with certain vintage style amps when I'm going for a blues or classic rock sound and I run one channel into the other for more gain. It's a shame that EHX doesn't explain this pedal better. I think many people who record acoustic instruments, or want to run direct to a mixer would really appreciate how nice this pedal can do the job.I own several EHX pedals & never had a problem with any.

    Save your money.

    By Mccs1977

    from up-state New York

    Comments about Electro-Harmonix Classics LPB 2ube Stereo Tube Preamp Guitar Effects Pedal:

    At best the LPB-2ube will slightly increase your volume and thicken (if not muddy) your existing tone. This is achieved with all setting at 12 O'Clock and the input level on low. On average it will add unwanted hiss and noise and suck tone like an old school Boss NF-1 set on max if you go beyond those positions. Worst cast scenario (and it's not all that hard to dial in) you will end up with a heap of feedback and squall that would make a My Bloody Valentine fan blush. Save your time and money and buy a BBE Sonic Stomp if you are playing solid state and looking to liven up your tone.

    I love it

    By OneCent

    from All Over Hell : Detroit

    Comments about Electro-Harmonix Classics LPB 2ube Stereo Tube Preamp Guitar Effects Pedal:

    I use this with my Blues Jr and 65 Deluxe Reverb in stereo with ho attenuators with both cranked and omg the tone is incredible almost otherworldy. It took a few minutes to adjust my ears after using the crappy in comparison solid state boss brand overdrive for so long. super wide headroom. A lot of players don't understand how to get killer distortion and think that these amps are for blues only. One word: WRONG. Putting another preamp in series with another preamp creates some amazing timbral depth, nuance and comlexity. Hendrix found out about twin reverbs cranked a long time ago.

    improves anything u put into it

    By Anonymous

    from Undisclosed

    Comments about Electro-Harmonix Classics LPB 2ube Stereo Tube Preamp Guitar Effects Pedal:

    This pretty spendy pedal doesnt have a lot of features , it has just good old fashion " if i turn up the volume loud enough i wonder how crazy itll sound" metality behind it. It does what tubes ended up being used for. It has the standard valve sound useing just one of the two channels together , nice and clear with a touch of warm tube wavering, analog signal, not the digital binary on and off wave form but a flowing one , I tend to leave the two channels chained together just send the line in into one then the out back into the other in and it uses both tubes together wich allows u to drive the second tube into total saturation.There is two drive knobs which u notice a mild overdrive be itself when set to max but sending it in to the right channel and out then to the left and then out to the amp u can adjust the drives together that gets some really nice old fasion almost static like breakup or really old classin guitar from the 50's 60's like breakup. And if u want it even more intense u just turn up the right channel volume to really push the left and it gets pretty crazy at that point. It can drive really hard by itself but u can also use other pedals goin in to drive the right tube before the left ... boosts work crazy to over drive the tubes... Im thinking about getting two so I can use one for mild overdrive and clean sounds and then kick on another for pushing it ... It really does stick to an older sound , im really into low fi and atmospheric rock with noise. But it honestly improves any over drive or distortion sound u currently have , it adds an extra ammount of color and warmth without takeing away any of the origonal sound ... its so great to kick on if you want to make your current driveing sound just a bit more instense without boosting it ... its pretty versitile , like your own simple tube amp.

    Sparkling Clean

    By Anonymous

    from Undisclosed

    Comments about Electro-Harmonix Classics LPB 2ube Stereo Tube Preamp Guitar Effects Pedal:

    I've had my Electro for 4 months, and it is well worth the money if you are looking for better tone. My current rig consists of a Les Paul Standard, a Boss multi-effects unit, and a Fender Hot Rod Deville. I have run the 2ube through Marshalls, Peaveys, Crates, you name it, and it makes just about any amp sound better with one stomp-regardless of make or model. This pedal's greatest asset is how it makes the cleans sound remarkably clear, while, at the same time, adding quite a bit of boost for solos. I have gotten so used to the 2ube that I keep it on all the time. As soon as I turn it off, my rig instantly loses depth. I have even thought about buying another-one to keep on all the time for clean rhythm sections, and the other to get a nice overdrive for solos. I don't know what I would do without this preamp. It is unbelievable!

    transparent overdrive

    By Swift

    from Housatonic, MA

    Comments about Electro-Harmonix Classics LPB 2ube Stereo Tube Preamp Guitar Effects Pedal:

    I tried this out with a P bass and a Fender Rumble. I ran the channels in series and it provided the clearest overdrive I've ever heard. Amazing tone, and variable from super clean to crazy distortion.

    Perfect pedal for right situation

    By hf4qdC3vu

    from Edmonds, WA

    Comments about Electro-Harmonix Classics LPB 2ube Stereo Tube Preamp Guitar Effects Pedal:

    I was looking to add some warmth and punch to my solid stage fender 2x12" combo. This puppy did the trick. At first when I plugged it all in and played, it was already on and I didn't feel like it was doing much. But, then I clicked it off and compared against my original tone, and boy was I wrong.With the pedal engaged, it sounded essentially like my tone, but with more depth, warmth and punch. I've got the drive knobs dialed back, so I'm not using it as a means to add distorion. Doing such, I lost clarity. But, it could be used that way in the right musical setting.As I use it, it's perfect for what I want. That said, I got it used for about half the retail price. I could see some folks hesitating to pay full retail for what the pedal brings to the table. But, now that it's part of my system, I wouldn't leave it out!
