well, first thing, you still need a buffer on your board. it might still be the fact that they are at the end of the chain, rather than the actual pedals themselves, were the tone is being lost.
If you do have a one your tone is only as good as your first buffer.
If you don't you might wanna turn on the DSP Bypass of one the Factor pedals.
i skipped the trouble and got the Redeemer Circuit from Creation Labs.
