(I guess its ok now. Iīve just corrected the typing mistakes.)
6 months is a lot of time. The expression pedal on my RPīs 6 and 12 started making a nhec-nhec noise in the first day. The knob of the 2101 fell off after the 1st month and the C1 was a good and nice piece of junk. The display used to stop working. I know 2 other 2101 owners and they used to have the same issues. The 2120 looks pretty cool but sounds like a toy. All those units were like a huge puzzle and they f*** with the guitar signal.
The Lexicon MPX G2 is pretty tricky IMO, but not as much as the RPīs and the 2101. And it sounds a lot better.
The only Digitech that works pretty well is the Whammy IMO.
If youīve bidded, donīt buy if youīre the winner. Nothingīs gonna happen.
Do you really want a versatile floor multi-FX with a expression pedal? Get a Boss GT-5! itīs not like the G-Force but IMO itīs the best floor multi-FX ever made. It sounds great if you conect it into a power-amp (Mesa or VHT) like I did once.
The GT-6 (that Adamcbest menctioned) is a great unit as well. Iīve tested one with a Road King head and itīs easy to use, cheap and extremely versatile. The owner of the Road King head connects the GT-6 using the 4-cable connection. I donīt know what exactly is that but it works pretty fine and sounds great. Iīve asked him to play his RK without the GT-6 and I realised that it doesnīt change the quality of the guitar signal at all. Thatīs very good and important.
I suggested you to try the GT-5 because of that unit on Ebay for 299 (Buy it now), but itīs your choice. I would buy if I was in the US at the moment but Iīm not
The GTīs 5 and 6 wonīt let you down; Iīm pretty sure.
The GT-3 that I had in the past was a hell lot better than the 2101 for example. I donīt have it anymore because Iīm trying to put a rack together. I just dont want you to spend a lot of money with Digicraps, Zooms or DODīs. Mere toys.
