I've been using a Sansamp BDDI with my Modulus Flea 4 for a little while now and really enjoying the tone. However, per the Sansamp instruction manual, I get my best tone by setting the active controls flat. Since I'm always running my controls flat, does it even make sense to have the bass remain active? So, my thought was to remove the onboard pre (Bartolini NTBT) and go with a passive tone circuit. Well, then I got to thinking that maybe I should just install an active/passive switch and leave the pre in there and do an A/B comparison that way. Will an active/passive bypass, engaged in passive mode, essentially sound the same as a true passive bass? Will it sound the same as the active set up with the controls set flat? Just for reference this is a Bartolini NTBT from 2000. What do you think? Would I get better response from the bass using an onboard pre with the EQ set flat or simplifying the setup down to a passive tone circuit?
