I have a Dingwall Afterburner with FD-1 pickups and passive electronics, and I have been looking to get a crisper slap tone when I need it. After reading up on the forums and taking advice from my previous posts, I believe what I am looking for is a good outboard preamp like the Fodera Model 2000, J-Retro, Bassbone, etc. I am looking for something fairly transparent, because I don't want to drastically change my tone. This is the case with my Sansamp BDDI, so I have that area covered allready. Most importantly, I would like to have a mid control for slap playing, which the Sansamp does not have. I play a wide variety of music, but my main gig is a contemporary Christian Rock/Pop band. In my spare time, I go for a funk/rock sound along the lines of Flea, Claypool, Trujillo, etc. Have any of you Dingwall players or dealers tried using your basses with any outboard preamps? If so, what are your impressions and recommendations?
