    I often play small rooms which mean lower volumes and tighter spaces. I've tried playing direct with my effects but always missed that extra my tube amps give. I've gotten smaller (Fender Blues Jr.) and smaller (Epi Valve Jr.). I decided to try this. Put right on my pedal board at the end of the chain and straight into my direct box. I'm sold. I'd probably still rather play my Valve Jr into the 2-12 K120's but so far I've really felt I am still playing into a tube amp. I use this as an amp replacement rather than an effects pedal and in that role it performs very well.

    I just got this pedal in the mail today and it took about 2 minutes to be seriously dissapointed with it. The problem is that it sounds so dull. Even with the bass EQ turned all the way down and the treble maxed out it just doesn't have any tone in the mid or high range. I know what I'm talking about and wish I hadn't read the other 40 reviews here raving about this pedal. The tubes distort well but unless you want to totally change the EQ on your amp then this won't have any of the tone you are looking for. I put this next to my EH English Muffin (which absolutely smoked it), Paul Cochrane Tim pedal, Hermida Zendrive, and TS808. I play through a Bruno Cowtipper 90 and Bruno UG30 with power attenuators on both. This pedal sucks. Get a used English Muffin for any type of soft crunch to full on rip. Better yet, if you want classic distortion start pushing a 6v6 tube amp until it rips.

    Tube me? well, Tube you x 2

    By J blues

    from FL

    I bought this used to save some cash and to beef up the sound of an old Line-6 Spider 75watt solid state amp I was considering selling...until I paired this pedal with it. Now its like a new amp and lots of fun again. Just like it's name states it is well suited and voiced for "classic rock" sounds and not as aggressive / high gain sounding as the Ibanez Tube King. I found the Twin Tube to be much more quiet (as far as unwanted background hiss) than the Tube King as well. The Twin Tube has a unique wall wart that is 16V "AC" which the manual states enables it to act like the pre-amp of a true tube amp and not required to run in "staved plate mode". I like Semyour Duncan pickups and glad I gave one of their pedals a try. I really like the 3 options it provides for rhythm ,lead and true bypass tones. The pedal appears to be well made with substantial weight = probably due to the internal transformer.I have not tried it with my Marshall or other tube amps yet but expect good things there too.Cons - It is a little pricey with a pretty large footprint plus has a unique power requirement.

    Only one useful mode at a time

    By Byron Marsh

    from Nashville

    If it had separate tone stacks per gain channel then I would easily see this being a very cool box. If you are looking for really high-gain sounds, maybe it would work for you. I'm primarily looking more for a bluesy tone now and I just can't get it out of this, certainly not two of them. As it is, I can only get one good tone out of it at a time and that tone has more gain than I like. If I hadn't had to wait so long before trying it out I would have returned it.
    Features are OK for the price. It had what I was looking for, the ability to switch between two different gain structures in one box.
    Seems well built. It would be pretty hard to destroy it.
    It is a little pricy for what it is, considering some small tube amps cost less.

    A Must Have

    I've purchased 'tube' pedals in the past and have always been disappointed. I was naturally skeptical about this little offering, but the idea of channel switching intrigued me so I bought one from ebay at quite a deal. THIS THING ROCKS!! I run it straight into my Fender Blues Junior, effectively turning it into a 3 channel amp. Add a boost pedal and you have an infinite array of rhythm and lead choices. The Twin Tube will cover all tones from cleans to Nashville to creamy Clapton to AC/DC. I intended to use this with my practice rig only, but the choice of tone and ease of use helped this little preamp find it's way to my gigging rig. I rated the value 4.5 because it may be a little pricey, but then something this simple and versatile doesn't come cheap. Highly recommended!

    Awesome

    By Jack AssHammer

    from Buffalo

    You just can't beat this peal. The sound quality is stellar. True tube tone. I've had 4 of these because I keep getting lured away with some seductive promise of a better sound/pedal only to come back and buy another one. I'm a pro player, these are just awesome.I gave it a 4 for features due to the lack of a mid control but hey my amp has a tone stack too. You will not get tone this rich with an op-amp.

    Twin Tube Classic

    For the type of tones that I go for this pedal works very well. I like to get that early break up sound,(Hendrix type rhythm tone) which channel one on this pedal does very well, and a very natural warm overdriven lead tones. This pedal is very true to its name "classic," it gives some very nice late 60's -70's rock tones. I gave it a 3.5 for features because the eq is somewhat limited, it has a good curve but you have to like it for what it is because there's not a lot of variation. If you're looking for a more modern scooped or "v" curve tone this is not you're pedal, (maybe try the twin tube mayhem). But for creamy vintage tube tone this thing is great. This pedal allows you to play with the feel of cranked tubes without all the extra volume so it works well for all sizes of venues, or just for practice levels. One of my favorate things here is the feel that this unit has. It is very spongy and touch sensative. If you set the gain right it cleans up very nicely just from playing softer and bites more when you dig in, and cleans up very well with the volume knob on the guitar, pretty cool for a pedal.

    Powerful and Flexible

    By nussmeier

    from aspen

    I run an electric semi hollow guitar into a loop station and go direct to PA for gigs. This is currently the only signal booster I'm using to give the electric some tone. Between the two channels, I get most of what I need which is pretty amazing considering I'm not using a guitar amp. The tone is warm, fuzzy and of course not as juicy / meaty as it would be through an amp but pretty good nonetheless. These tubes definitely take a little while to warm up and peak. The tones get much more palpable after the pedal has cooked for an hour or two. Definitely play one first like anything else tone-related, see if its a mate for your gear.

    Warmth

    By Narrowgate

    from Suisse

    This a really great unit. The warmth is truly amazing (can't beat tubes!) Anyone who does not like the sound of this has either a poor amp, or poor ability. Although I do have a couple of issues, the footprint is rather large, and in less than a year the tubes went, and I was not gigging heavily with it. Overall, quite satisfactory.

    The best pedal

    By Mr. Tone-HYU.X

    from San Francisco Bay Area

    I've had this unit for 3+ years now. The tone is incredible! It has a very warm tube sound. I play SRV type blues/Satana and classic rock. This unit coupled with my Mesa Boogie 2x12 Lone Star is pure heaven. A reviewer that rank this unit low,obviously can't play and/or doesn't know what he's doing. I haven't had any problems. This is a great buy.
