Im just trying out my boss today and its not making any difference, i could have hooked it up wrong but i dont think so
I dont have a confusing chain its just <amp-NS2- DigitechMM- viper 400>
but when i turn it up loud it squeals terrible, iv got both the nobs turned to min. But when i turn the MM off its perfect, what could be the problem? do i need to mess with the MM or change stuff around on the NS2
im running through a general half stack btw

If anyone could give me some suggestions id really appreciate it
