have tried 707ii, gfx1, gfx4, g1x and they are all ok. (though 707ii) stand out among the rest (soundwise). gfx4 oks na oks din kase dami apakan (though manipis ung dist).
I've also used Korg AX1000g, Boss ME-30 and Floor POD Plus - these 3 are so so.
now I'm using gfx5. And I must say, this is the best among them all.
Disclaimer: dipo ako mayaman. na experience ko silang lahat sa tulong din ng philmusic. buy ng gadget, kalikot kalikot for a month or so, benta then bili ulet. ganun lang. dika nmn maluluge, sa experience palang panalo ka na. That way, you can tell yourself what fits your preference and simply say na try ko silang lahat.
Multis I like when it comes to distortion: GFX5, 707ii, gfx1, Korg AX1000G, (diko lng trip modulations netong korg)
Modulations: GFX4, gfx5, 707ii
Cabinet/Amp modelling: Floor Pod. Oh yeah!
i've considered the rating accoriding to performance vs. the price.
I'm still eyeing in getting higher models of multis like g7, me-33, me-50. gt6 kung me pera.
As for now, I'm extremely happy with my gfx5. kahit sa price or performance, gfx5 ako. Though I expect my patch pedals to break. anyway, dyan nman si ricabb e. (planning to go to a music store to try that g2. na curious ako sa reviews nyo e. hehehe)
di naman ako fanatic ng zoom talaga. It just so happened na, mahusay gawa ng zoom and for the price, deeeeym...
peace out.
