Hello all. I was wondering how many sovereign gt users have had the mod by msr which is supposed to give up to 3 inches extra depth. So I wondered if it is worth it and how the mod measures up in the field. I have seen 2 posts where users claimed to have an extra 2.6 inches of depth. Are there any other changes in performance after having the mod for instance does tone change or does the machine become more unstable. Also does the mod have a switch that applys it so that the mod can be switched off and the machine revert to pre mod operation giving the user the choice of detecting with the mod or without it . Thanks in advance. Davey.
