hello! sorry for the "urgent", but im in argentina only for 5 more hours and need to take this decision, and i thibnk you can help me..... i need a envelope filter for both proyects i got, one is primus-like andd the other is experimental, with lots of pedasls and stuff.... i already ordered a mig muff, amd have some other pedals like korg AX1B.... the only 2 pedals that catched my atention here are the MINI QTRON and the TUBE ZIPPER . (thay dont have the normal Qtron) both are overpriced, but since this is the only chance i have,and since i spend a lot less in something else that i was expecting, i have the spear cash. the zipper has a LOT mire options, like for exapmplpe 2 filters, so it will fit the experimental proyect a lot more, but my questions are: will i be able to archive what the mini Qtron will give me with the t.zipper? also somebody told me that Tzipper tend to break manybe this is becasue of changing parameters a lot, any input here? i WILL be changing a lot parameters in real time, so this is an important factor.... thancks a lot for info, and please feel free for adding any info to consider.... both pedals are new. THANCKS A LOT!!!
