Replaced hi-gain with a toaster on my 4003

I've posted pics of my new Monty Brown with replacement guard, toaster, knobs...on another thread but, I just finished a practice session using that bass and I'm amazed at the array of tonal differences I can get since I put the toaster in there. The toaster brings an amazing warmth and bottom sound to the bass.
Now, I have Pyramid flats on there but I could play any type of music and it sounded amazing. From my practice of The Beatles (Birthday, I Saw Her Standing There, Can't Buy Me Love, All My Loving) to Rush (Freewill, Red Barchetta, YYZ), to Yes (Yours Is No Disgrace, Starship Trooper).
All of this could be achieved using only the different pickup positions.
I've contemplated buying a horseshoe pickup to complete "the look" of the vintage Rick, but I don't think I want to now that I've been able to get these tones. Anyone else had a similar experience??? Believe me, I'm playing through a cheap Crate combo amp. If it sounds this good through that, I can imagine what it would sound like a GOOD system!!!
I've been contemplating upgrading my rig and am leaning toward the Yorkville/Traynor system:

Any thoughts or similar experiences when switching out for a toaster???

To me, toasters are a key element to the Rickenbacker sound. I can get a wide range of tones like you have found, and that is with flatwounds also (Chromes).
