Yep, I gotta Digitech RP-100. It is great for the money and pretty versatile, but gotta agree with some others that it does lose some tone somehow through an amp, or at least compared to how it sounds direct out with headphones. Previously I've always bought dedicated pedals such as Boss tube screamer and such, but just from my perspective it's alotta of hassle going that way. 9 volt batteries are expensive (multiple wall worts are a mess too), lots of patch cords, and god forbid you need to turn off/on more than one pedal at a time, on time. Concluding, these multi-effects are not a solve-all solution. But they do a lot of things well, conviently.
