Ya, the 606 (why soooo many 6's???) is a nice jewel for newbies (like me !!!!) but it does lack some features, which you'll discover AFTER you've bought it and took it all the way back home !!!!!!!hehe...
No, i'm pretty satisfied with it but, I miss the cool delay+reverb fx, although the ECHO-preset-kina'-stuff does try to do that, but you don't have much control over the delay. Sorry, if you're tryin to play Duur (Strings) or still...imitating Mr The Edge (U2)!!!! (Ya, these onche log don't use a small fx unit of a couple of thousands of rupees and are no match for small 'room guitarists' like me!!!!!)
Another thing, the wah or expression pedal moves over a small range and doesn't give you much control (or expression)...but still, it is far better than the small fx units I used to make as an electronic hobbyist...So if you wanna really cool wah, better opt for a separate 'Cry Baby', which is THE reference in wah!!!
Hey, by the way, main koyi 'oonche log' nahin hoon, yaar!!!
You see, here in Mauritius, when I went to buy my fx box, I got the choice between Zoom and Digitech units...(Actually we have only two music gear dealers here!!!)...I fell for the black 606 which was a nice cozy little monster and matched my 'black baby'!!! The GFX8 is a very very good stuff but far too expensive for me 'Chhota Aadmi'!!!
Ya korg's distortion's very good, I've heard it...but I like the heavy dist I get on my unit too...You can downtune your guitar ON THE FLY with the built-in tuner, select the HEAVY distortion preset and start playin, let's say Blind (Korn)...phew!!!We're rockin, man!!!
Greets fly to Lordneo, esp for the beer smileys!!! ;-)>
