The transmitter from the POD GO Wireless won't fit in two of my Ibanez bass guitars (models: SRFF805 & SR300). I have two other (older) wireless systems that fit my basses without any issues, but this one it's thicker and won't fit in. I Had the regular POD GO and I changed it to the wireless version to find out it doesn't fit my basses. This is frustrating. Any suggestions?
