In the Duncan world you have, in ascending order:
STK-S4n (Classic Stack Plus) & STK-S4m (Classic Stack Plus RWRP)
STK-S4b (Classic Stack Plus Bridge)
STK-S7 (Vintage Hot Stack Plus)
STK-S6 (Custom Stack Plus)
STK-S9 (Hot Stack Plus)
Just because the S4b says Bridge, you can use it in any position, same for all the rest. The “classic” calibrated set is S4n/S4m/S4b (vintage neck and bridge and just a slight bump
in the bridge for balance). If you want to bump it up a level you can do S4b/S4m/S7 or S4b/S4b/S7. There’s a great video of Jack Thammarat with the S7 in the neck.
Basically, there are a ton of options in the lineup.
But aint the STK-S4 bridge specs the same for neck?
