Hi! I had owned a Forte 5 last year...awesome bass! The neck profile was a D shape, not fat but quite thinner compared to some Euro's and Korean made Spector 5 strings I've owned. The pre was the Aguilar OBP 3, three band, LOVE it! I modded it to 18V, can be dialed in any where from clear to dirty. The String to fingerboard action was crazy low and FAST. Only sold it to pay for my Coda 5XL Deluxe, bolt-on neck.
The Coda 5XL Deluxe neck is retro to the Fender 60's jazz bass...thinnest (front to back) 5 string neck I've played to date, very flat, very very low string action and super duper fast player. The pre is the Aguilar OBP 2 @18V, clean clear tones to gritty dirty, I LOVE the Aguilar pres, with the OBP 3 as my favorite because of the mids control.
A year ago I would've sworn to you that I was a "Neck-thru" bass only, for life...but after having my USA Coda 5XL DLX for 7 months now...I believe the USA Spector bolt-on's are way ignored and best value in the USA Spectors. You won't go wrong with ANY of the Spector basses or electric guitars.
As for preamps...I've played the TonePump Jr., TonePump without trim, TonePump with trim, BT circuits, Korean 9V Haz Copy, Aguilar OBP 2, Aguilar OBP 3...but not the Spector USA 9V circuit or 18V circuit. So far the Aguilar OBP 3 is my favorite because of the mids control and at 18V it comes sooooo close to the tone of the Spector USA 9V circuit at half the cost. Hope this helps you out some.
