This is a solid state practice amp that puts out 10 watts. There are inputs for input and headphone. The amp has knobs for treble and bass. It also has a button to engage gain or drive. A volume knob controls the amp in both the clean and gain settings.

Being a simple practice amp, the general configuration is straightforward and self-explanatory. The controls are responsive for a practice amp and you can easily get a decent sound being a practice amp. This was bought new, but it did not come with a manual.

Because the power is not adequate and the speaker is not that big, it is hard to get a variety of useful tones out of this unit. I didn't even bother putting pedals through this amp, it probably couldn't handle it. (Oh, I did go through my DOD YJM 368 before plugging into this amp, and the feedback/noise was ridiculous!) I used to use the Squire Stratocaster that came with this amp in a package. I also used my current Ibanez rg-120 through it, and they both sounded decent. (Once again, remember that this is a practice amp.) ONce again, because it's only 10 watts with a tiny speaker, the clean sound is only passable. (Hard to say that about a Fender, but it's not fair to expect it out of this unit.) The distortion is actually pretty decent, especially at lower volumes. The only problem with that is you definitely can't jam with this amp, especially with a monster drummer

I wanted to start putting together a small personal computer recording studio at home. So I thought this would be the centerpiece or at least the starting point of my system as it is a computer interface for your guitar to go right into the computer. I bought it with the expectation of being able to use the unit and the included software on both my laptop and my desktop computers. I only have an electric 6-string right now, but I can also put an electric bass guitar through it as well, among other things. Simple single input. Also has a output for either headphones or computer speakers/monitors.

Installing was pretty easy. Just followed the prompts, and the install went well. I don't believe there were compatibility issues at SETUP. The general configuration of this unit is simple and the manual is clear and sufficient.

The drivers appear to be stable. I don't have any reason yet to think otherwise. I have never had the drivers updated, so I cannot address that. I use the included gt-express software, which provides virtual floor pedals and effects. The software also has a virtual rackmount function which has built in drum loops that you can design, put together and loop while you play the virtual guitar sounds. You can also load mp3's of your favorite songs, or sample drum loops from pro tools that are included, so you can play along. The latency is not completely horrible, but it's bad enough that this unit is not sufficient to fill my recording needs. There is no recording software included with this package. There is a recording feature on one of the rackmounts, but it's only one track at a time, and you can't record the drum loops or accompaniments with it.

This is a tube microphone preamp. It comes with a 12ax7 tube. Because it has tube technology, I bought this to add some warmth to my live rig. It has 1/4 inch inputs and output as well as a balanced XLR input and output. This means you pretty much have a stereo input and output capability with this unit. You can also go direct with an XLR input into a mixing board with this unit. I would call it rackable, as it is definitely not a floor unit. It is very small, so it can go on top of your rack, but also on top of your amp,preamp, power amp, or speakers.

The configuration is fairly simple. There is an input and output knob. There are also buttons for gain, p.power, phase reverse and OPL. Basically, you turn the input knob to adjust the volume of your input, and turn the input knob to adjust your output volume. The effect of both can be heard through your speakers. The manual is clear and sufficient. There is really nothing much to this unit to understand.

I bought this preamplifier to add more warmth to my rig, as my Fender Stage 185 tends to have a harsh treble. So I really did buy this unit to "color" my signal in that respect. Unfortunately, I have to realize that this is a microphone preamp, so running my guitar through my pedals, then through this unit before going to the board will not make my "house" tone sound good. As a matter of fact, it sounded very weak. So I broke down the next week and mic'd my amp then sent that signal through this unit, then to the mixing board, and I sounded much better through the house speakers. Don't know for sure if I sounded warmer than through my amp, but at least the sound through the house was decent. I think this unit will also make miking my acoustic guitar sound great.

This is a pure delay pedal. You can also get chorus and slap back echo out of this unit, among other sounds. I believe it is digital and cannot be edited via computer. It is a floor pedal, so it is not rackable. It has two stereo inputs as well as two stereo outputs, great for bi-amping !

There are four knobs: E. level, feedback, delay time and mode. I do not have a manual, because it's used. So if you don't know much about delay, like me, you can play with the pedal for a time and figure out some really cool delay effects on this thing. Switch the mode around, and you get several different effects within one pedal. E. Level is like your volume. Feedback is the amount of delay you get, and delay time is the duration of the delay. Pretty straightforward.

This is one of the best pedal delays in the business. Don't mess around with other delay stomp-boxes, this is the one to get. I put this pedal at the end of my pedal chain. I use the stereo output to bi-amp and the "ping-pong" effect that occurs at certain delay settings is really cool. Reminiscent of Pat Metheny on clean settings, Van Halen on distortion settings. I use 80 millisecond mode to add a little light delay to my solos. Gives it some nice "sustain", but not so much delay that notes start bleeding into each other. AT 300ms, you have a chorus type effect. Pair it with another chorus, and it sounds very lush and full! AT 800 ms, you've got a slap-back delay or echo, perfect for country or bluegrass music. At 2600 ms, you've got some wicked tape delay ! There's even a setting that makes your electric sound like a violin !

This is an equalizer. It can also function as a volume booster, which is great. I believe it is a digital effect. It cannot be edited via computer. It is a floor pedal,so it's not rackable. It has input and output as well as connector for 9v/dc power supply.

The general configuration is your standard 7-band equalizer. I don't know anything about equalizers and setting them for specific applications. This is where the manual/instructions came in. I made it easy to tweak the slider controls and get various tones from the unit. There are 3 sample presets: barb-eq for blues or 70's rock, scooped for metal, and curly Q for God knows what?

This unit provides top notch equalization for under $35. When you stomp on it and engage it's effect, it is almost like you just engaged a sonic maximizer. It makes your tone jump to life and just improves its presence that much more. It also works great as a volume booster for solos. Just slide the level to over 1/2 all the way to full, then stomp on it when you're solo begins! There's nothing I really don't like about the tones from this thing. (Aside from perhaps the "Curly Q" setting, which I'm still not sure what it's for.)

This is a pure distortion pedal. You can get overdrive out of it, there are even presets for it. However, I believe this pedal is specifically tailored for hard, heavy, driving distortion. The heavier, the better. It is a digital unit and cannot be edited via computer. It is a floor pedal, so it is not rackable. The unit has one input and two outputs. One output is for going to an amp. The other is a cabinet modeler that allows you to go straight into the mixing board.

Configuration is simple. It has four knobs : level, low, mid and high. As digitech says, they've set the gain on 11 and ripped off the knob ! Thus the lack of a gain knob on this unit. Sounds/effects editing is very easy and the clear, colorful manual makes it even easier. There are not only presets for just this unit, but the manual also shows how you can combine it with other effects to get a solo tone.

This pedal really only serves one purpose....it's a death metal pedal, just like the name says! As such, it sound greats for death, trash, nu-metal, and even heavy metal! I put this thing through a Fender Twin and it was palm muting hell (or heaven depending on your opinion.) It is great for heavy rhythm grind. Unfortunately, because the treble is so harsh, I don't feel this is a great pedal for soloing. The manual has a sample setup that has this pedal chained to a delay and a chorus for a smoother soloing sound. When I mimic this set up, it sounds a little better, but the treble is still too harsh in my opinion, even with the delay and chorus.

This is a straightforward overdrive/distortion pedal. It actually has a mode for both overdrive and distortion. I believe it is digital. It cannot be edit via computer. It has input and output, as well as connector for 9v/dc power supply. It is a floor pedal, so it is not rackable. It has volume, gain, treble, mid, bass, and frequency in stacked knobs.

General configuration is simple. Even though certain knobs are stacked on top of each other, it's not really hard to figure this unit out. This pedal can get a large range of sound or effects and editing is easy. I bought this used, so I don't have a manual. However, if you go on the Marshall website, it has some pretty cool presets that you can set up.

You can get some tones that are fairly close to several Marshall amp models with this unit. For distorted sounds, I have as much as put this through a Fender Twin, and it sounds huge and amazing. It's like having a Marshall amp with the purity and thumping low end of the Fender clean. The distortion mode on this pedal has a ton of bass to it, which I like for solos. However, in order to switch back to rhythm sounds, you would have to bend down and switch the mode to the overdrive mode, which is not very practical in a live setting. The same goes for switching from rhythm in the overdrive mode to playing a solo in the distortion mode. So basically, you need to have another distortion pedal or a dirty amp for playing rhythm, then kick on this pedal in the distortion mode. Or you have to use this pedal on the overdrive mode for rhythm, then have another pedal as a gain booster, such as a DOD YJM 368 when you go into a solo. So it's pretty impractical, when ideally, you should only need this pedal to switch between rhythm and soloing, and back. Since I have a multi-effects pedal as well as my DOD preamp/gain booster, this pedal only gets used for specific applications.

This is a straightforward preamp overdrive. It can be used by itself as an overdrive pedal. (I don't like the sound that much when used in this way.) It can also be used as a gain/preamp booster, i.e. in front of a dirty amp or in front of a distortion/overdrive pedal. I believe it is digital. To my knowledge, it cannot be edited via computer. There is an input and output, as well as an input for 9v/dc power supply. This is a floor pedal, so it is not rackable.

Configuration is very simple, with just two knobs: level and gain. Getting the intended effects is really easy. Turn the gain all the way up, then adjust the level to your liking, and you're done with presets. I think I have the manual, but I don't think it was very useful. Luckily, you don't really need it.

As I said earlier, as an overdrive by itself, I am not so impressed by this pedal. However, when I put it after my noise suppressor and before any distortion pedals, it makes a wonderful, screaming preamp booster. I stomp on this baby primarily for solos, either with a distortion/overdrive pedal already engaged, or when the amp I'm using has it's drive/distortion pedal kicked in. It gives you days and days of endless sustain. I can also do fast,long solos without wasting all of my hard earned energy trying to press the strings so hard to get great tone and sustain. The only things I don't like about this pedal, I fixed by buying additional specialized pedals. It is very noisy, especially with the gain turned up. A noise suppressor fixes that. I also wish that it would boost volume when engaged, precisely because I use it for solos, but this unit does not give much of a volume boost when engaged. So I bought an equalizer that I can engage along side of it when it's time to solo.
