Hello everybody.

Inexpensive, comprehensive and easy-to-use device.

The USB connector is great because it allows me to use the RP as an external stereo sound card with volume control (and the sound quality is much better than that of my old computer).

The user interface is very simple, which is a great advantage compared to the Korg AX3G, even though I also like it, but it's a totally different concept.


Everything is labeled on the device and it's very easy to move through the parameters. It's one of the main advantages of this device.

If you want more, simply use the USB connector, download the Digitech software and install it (it doesn't work immediately with Win XP SP2: you'll need a Microsoft update).

Once you get the software working you're possibilities are endless. I especially love the duck delay (see my Rocktron Intellifex review).

The mixer/amp control makes wonders and I appreciate the separate 1/8" jack output. The unit also has two 1/4" mono outputs... It's much better than Korg's inconvenient all-in-one solution.

I give it a 10 considering its price.


Several music magazines praised the quality of the reverb effects, some even went so far as to compare it to a Lexicon, but I'm quite disappointed. The reverb effects of my Korg sound much nicer.

It's the same with the RP150's octaver which sounds very synthetic but it's a real highlight of the Korg.

The EQ is nice and you can use it on its own (or with compression and reverb for example).

Many amp distortions.

It sounds a bit too clean but clear and fresh. You can also activate an overdrive PLUS a slightly overdriven amp model (great for solos) with a single button.

These applies to home or headphone use but not to band rehearsals. The sound is too sharp and not powerful enough... Anyone with an MG Marshall can get a better sound.


I bought it as soon as it came out. I use it frequently as a headphone amp with my distortion pedals (great results with the blue GDI21) or as an interface between my electro-acoustic guitar and my Samson 40A monitors (also a great combination).

When I play with my band, we use it either as delay/reverb effect or as an interface between the distortion pedals and the mixer (or keyboard amp) for people who don't have a guitar amp with enough output power.

I find the unit is a good choice considering its overall sound quality, numerous possibilities and price. And the ease of use makes it a great tool to start out.

I give it a very good mark (I believe I recall a Metal Zone pedal had the same price a few years ago...)
