The Eclipse is a very different unit to Pitchfactor, program change wise there is a slight lag when going from one preset to another…but not when you are engaging / bypassing or manipulating the parameters within a preset.

As the others say though, it is not likely to "solve" the issues you are having.

i went from running a rig with 3 factors in to an Eclipse and in all honesty I did not notice any improvement or degrading of the signal…but then I never had an issue in the first place with "tone suck"
