Incidents , you can buy any good multi-effect unit to get the rest of the effects... think of Boss GT-x , Digitech GNX-x , or the Roland VG-8.

then all you have to do is to connect your wah pedal into the effect loop of the unit you bought.. I do this with my GT-3 , and it's very cool since you can controle the Wah pedal to be On/Off by the controle pedal ..

But I still need an All In One multi-effect .. as i said before, i love the sounds i can get from the GT-3 ... I just need to know wether the VG-8 , GNX-3 or GT-6 have the same Wah problem or not ..
