There's clearly demand for good multi-FX solutions that don't cost the earth and don't have amp modeling. It seems strange to me that more companies don't offer such an item. I've been looking at 4 units seriously so far and each one has its problems that you'd think could be easily fixed.
TC Electronic G-Major
Great effects but you'd need to buy drive pedals seperately as well as a Wah and a MIDI controller. It starts to rack up the cost and why buy an 'all-in-one' solution if you still have to buy additional pedals. There's the G-System of course but that's SERIOUS money even used.
TC Electronic Nova System
This is so close to what I need but again; no cigar. It has the drive section and it's even analog so it should be better than the digital offerings on other multi-FX but for some insane reason, you can't use the drive section as an overdrive for your own amp. I suppose if the drive section has a fantastic tone it would be OK but it would need to be going from light crunch to modern high gain to cover all my needs and remain tight enough by itself not to need an overdrive pedal to tighten things up a bit. I haven't yet had a chance to try this so I don't know if it can or not but from what I've read, it probably can't. Why buy a multi-FX unit to go with your favourite amp if you then can't use it on your amp's drive channel? The lack of an expression pedal is also a pain as I'd need to buy one of those too, if only for Wah. I also believe that there is some latency when changing patches and effects, which I imagine would soon become a pain. No latency, an expression pedal and the ability to use the 4CM would this pretty much perfect.
Line 6 M13
Sounds like a great idea and at first, four effects seemed like more than enough for me but then it struck me that if an EQ was one and a noise gate was another, both of which I use on almost every song, I'd only actually have two effects left to play with, which would be overdrive and delay. Anything else may have to be bought seperately, including a Wah pedal. On top of that, as with all of the Line 6 products I've tried, they tend to be very 'digital' and artificial sounding. The drive effects are usually very poor so I may need to use a seperate overdrive pedal which defeats the object of what I'm trying to do.
Boss GT-100
This one annoys me because I'm paying for a pile of amp modeling I'll never use but I'll grant you, that's not the end of the world. I imagine things like reverb, flanger, phaser, chorus and delay will be fine. If the noise gate, compressor and wah are better than on my RP1000 that would be a step up but as yet I have no idea if that's as good as I'd like and of course, we end up with the issue of a multi-FX unit's perrenial bugbear - the quality of the overdrives and distortions. It seems to me that this is invariably where multi-FX units fall down so this may well prove to be the acid test for this unit.
