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.

This is a straight noise suppressor with really only one purpose: and that's to suppress noise ! I believe it is digital. It cannot be edited via computer. This is a floor pedal, so it is not rackable. This unit has an input and an output for going from the guitar to the rest of your guitar pedal chain then to the amp. However, it also has additional send and return inputs and outputs, which essentially turns your pedal rig into an effects loop. This unit is definitely most effective when utilized in this way.

The general configuration/setup is simple. Sound/effects editing is easy. It's got two modes: one to mute your signal and the other is the actual noise reduction mode. It's got two knobs, threshold and decay. You need to tweak these two knobs to get the maximum, most effective noise reduction possible without compromising your tone and sustain, which the unit can do if you set the threshold too high. I bought this used, so I don't have a manual. However, I don't think it's necessary.

As said, this effect is for one thing and one thing alone. It is for noise suppression. It does what it does very well. It reduces hum, feedback, and other noise very well. I own a DOD Yngwie Malmsteen preamp overdrive pedal, and Yngwie himself will tell you that that little unit is noisy. When you put this pedal before the DOD in your chain, utilize the effects loop function. You can hear the wonderful sustain from the DOD without the annoying noise, as long as you don't set the threshold too high, thanks to the Boss Noise Suppressor.

This guitar was made in China. It has 22 frets and is a straight acoustic guitar. (i.e. no electrical components.) The bridge is stock plastic (?) bridge. No setting controls, as it is a straight acoustic. It has a mahogany neck and a rosewood fretboard.

The back of the neck on this guitar is nice and smooth and let's your hand slide easily up and down the neck. Because the guitar needs a set-up, the action is not that great. So I use this guitar as a practice guitar to strengthen my hands and improve my picking and fretting accuracy. As with most dreadnought style acoustics, it is difficult to get to the top notes/last frets of this guitar. I guess if you want to play high note acoustic solos, you need to get an electric acoustic with a cutaway. This guitar is light and easy to move around with. It's not so big that it's not cumbersome to play, which is great. At this price point, this acoustic sounds great. When playing chords, the sound coming out of the sound-hole is big, full and bright. It sounds better than a few thousand dollar acoustic guitars that I've played, in my opinion.

I play for a worship service, and sometimes we play some acoustic tunes. I haven't used this acoustic on stage yet, but I think it would sound great either miked or if I get a pickup for it. Like I said, I love the sound of chords coming out of this thing. Because of the action, playing single notes don't sound that great. You've got to focus on fretting properly instead of zoning in on your vibrato, etc.

Manual: http://www2.yamaha.co.jp/manual/pdf/emi/english/port/PSR90E.pdf

- What type of keyboard (synth, piano...)? How many octaves?
This is a 5 octave electronic keyboard, not a synth nor a piano. Not even close.
The touch is like most synths: ok, but no dynamic touch or after touch here. This is an extremely basic machine with crap sounds and it was probably extremely overpriced when it came out around 1982. However, if you stick it through some good effects, i'm sure you can use it quite adequately.

- What connection types are there? (audio, MIDI...)?
RCA stereo out, some sort of effects loops out & in (still stereo RCA) but i've never used that...MIDI in & out...exp pedal and footswith. Power is a separate adaptor.
The keyboard comes with a plastic & metal stand that fits on it and lets you have sheet music to read while you're playing, as seen on the photo here. You can take this off.

- How many different sounds and/or styles available? Can they be edited?
Not a lot. Check the manual but we're talking about 24-36 here.
You can't edit the sounds other than add chorus, reverb, portamento.

The rhythms are the only reason one would want to buy this, along with the fact that this is a very simple drum machine with some fairly decent sounds, surprisingly enough.
The rhythms are cheesy & fun, it's great, you can have a looot of fun with this. Plug it into an expander (i used my Roland GR-30 MIDI guitar expander with no probs) and you can actually have a good time, but i'm not sure you can do much with this thing apart from that.

- Is there an effects section?
Nope

- What are the features/characteristics of the sequencer?
4 tracks, you can save to cartridge if you find any on the second hand market (good luck) or to cassette or minidisc. Those of you who have had a Sinclair ZX Spectrum or a Commodore 64 will know what it's like.

- Is the general configuration/setup simple?
Oh yeah!

- Is the sound or effects editing easy?
The what?

- Is the manual clear and sufficient?...
Yep.

Made in Mexico. It has 21 frets with two single coil configuration. The bridge is a fixed stock Fender bridge. One control for volume and one control for tone. Has a three-way selector switch. Not sure what the neck is made of, but it doesn't feel like an expensive wood. The action is OK, mine needs a good set up.

The neck is OK. It doesn't play well since the strings are old and it is time to have it set up. With the double cutaways, it is easy to access the top notes. Unfortunately, with only 21 frets, you don't get much range. Being a smaller scale and what I consider a beginner guitar, this one is very light. It's your typical strat style design in a smaller, more 60's or 70's design. When this guitar was younger, it actually sounded decent, especially through a Fender Twin. It needs some TLC now, but I am unsure if that will even make it better for me than my beginner Ibanez. There simply aren't enough frets, and the guitar needs to be bigger for a bigger sound.

This guitar can do in a pinch if I break a string on my main guitar. Not exactly a metal guitar or even a shred guitar. It's nice for smooth, slow solos. It's also easier on the hands as it is a smaller scale, but that doesn't really help one's development and hand strength. I used to plug straight into whatever amp I was using at the time. Since I don't use this guitar much, it doesn't get plugged in to my current setup much. Like I said, it's not that great for metal or hard rock. But it can work for that jangly 60's and even 70's sound. I guess you could play Santana, or David Gilmour with it. There is a cool sustained harmonic that automatically appears when you play the 5th fret of the 3rd string, without having to pinch the string or purposefully attempt to create a harmonic. It is probably the coolest signature of this guitar. This is good, because I don't feel it has too many other cool features.
