like i said this thing dosent sound very good and it completly eats the tone of anything going into it. But hey, this is by no means a pro grade unit. as a first fx unit(which it was), it was very usful to me because it has all the main fx plus more. I now understand most effect types and know what i want out of my sound. I wrote many-a-riff inspired by the fx this thing churned out. But as my playing, my sound, and my cashflow matured i switched to a good tube amp and a handful of single fx pedals (now looking at a boss gt8, very cool but extremely complex.
Bottom line is: cheap unit, good for jaming by yourself and with mates but horrible if you want a good sound that you can gig with.
