Just got the AX30G from a friend who shelved it for almost two years, one week lng ginamit. yep, halos lahat ng karamihan ng multi-fx eh ganito, pero the delay doesnt necessarily destroy ur playing ... KOrg somehow made it that way par ma minimize ung 60 cycle hum ng gamit kapag malapit na sa stage light etc. But if it doesnt work for you, what I would suggest eh trade your AX box to something that suits your needs. Kung ako tatanungin mo...I'd keep it still, kasi iba pa rin ang sound quality ng Korg kung ikukumpara mo sa iba..
By the way ser sushi, naghahanap ako ng ka tag-team sa paggawa ng patches for this equipment, if you want we can share ideas, ask mo rin ung ibang mga ka forums natin dito who own or previously owned AX30 to bring in their insights about the fx box, as far as Im concerned, I like the way this sounds, kailangan lng talaga ng analysis on tweaking the patches.
