BOSS RC-2

Today we're gonna talk about a type of pedal that can really kick your playing to the next level. I'm talking about the loop-station, more precisely, the BOSS RC-2. Yeah, a compact pedal again, I want to get to review them ALL, and even better, post my own videos demoing them. These being said, the RC-2 is a magnificent tool holding no less than 16 minutes recording time. In my opinion, when talking about such a small tool, this is IMPRESSIVE. This is topped by some really GOOD drum patterns, way better and more realistic than what you'd find in your cheapo guitar effects processor's drum machine; an auxiliary input, to record signal from an external source (like, for example, other drum patterns, a backing track, etc.); undo/redo; footswitchable with an external BOSS controller to navigate through phrases etc.; 11 phrases can be stored and recalled.

Here's it's demo, hosted by none other than Johnny DeMarco. Unfortunately, it's one of his sloppy demos (actually, the first sloppy DeMarco demo I've seen):

BOSS DD-3

The BOSS DD-3 is a remarkable digital delay pedal with three delay modes and a very interesting hold mode. It's the entry level stompbox in the BOSS DD series.
So what's it all about?
If you've looked at the photo, you'd probably figured: the "MODE" knob, the last one, controls the delay time range that the "D. TIME" knob controls. The first position allows the "D. TIME" knob to control a range between 12.5ms and 50ms, the second position allows for the control of the 50ms - 200ms range, lastly, the third position allows for control in the 200ms - 800ms range. The "HOLD" option holds your delay forever allowing you to create some interesting effects.
The feedback knob controls the intensity of the delay.
Finally, the level knob is quite self explanatory.

Here's BOSS' mp3 demo of the stompbox:

BOSS TU-2

The BOSS TU-2 is a stompbox chromatic tuner (a tuner in a pedal!) that delivers all that you'd expect from it.

Here are some of the features:
-BIG BRIGHT LEDS YOU CAN SEE ON STAGE (really important for a tuner!)
-special BOSS tuning system: the LEDs move slower as the string reaches perfect pitch, and faster if you get farther away from it
-adjustable reference pitch: from 438Hz to 445Hz
-a wide tuning range of 8 octaves
-several tuning modes including: chromatic, guitar regular, guitar flat, guitar double flat, bass regular, bass flat, bass double flat (personally, I prefer chromatic ALWAYS)
-the tuning modes and display style are stored in the memory of the device
-footswitch mutes, bypasses and shuts off LEDs to preserve power.

It doesn't have:
-BOSS' AccuPitch (some BOSS tuners have this, the tuner beeps when the string is perfectly in tune so that you may "maintain eye contact with your fellow bandmates"; even if it did, it wouldn't have been of much use)
-a mic (nor would anyone expect it)
-a beep to a reference pitch (ex: A440)
-a metronome

The things it doesn't cover are covered BETTER in the other BOSS tuners, the TU range being: BOSS TU-2, BOSS TU-12, BOSS TU-12H, BOSS TU-15 and, finally the TU-80 (which also has a nifty little metronome).
