BSR B Circuit

[Greg Lorisco]

This may have already been asked, but is it possible to put in the new 3 band circuit into a BSR B? Will it work with the existing pickups?

I assume the BSR B doesn't have the mid frequency dip switches?

The DIP panel is for all 3 bands. Not just for the Mids. The BMT is a 3-band EQ circuit. Your bass has the 9v BT of the BMT unit. An extra hole can be drilled (maybe without damage to the finish) and with some chiseling, squeeze the Mid-board in and attach it to the BT 4-knob unit. The 18v unit needs more room that your cavity has. It would need a complete re-route and that would be difficult to do without damaging the finish.


This is the 18v unit with the DIP panel which needs more room than you have in that bass.

So the 9V BMT circuit has the DIP switches as well?

And it should fit with drilling another hole for the mid pot/board?

Right?

Also, what frequencies are available for the mid DIP switches? 200hz to 800hz?

So the 9V BMT circuit has the DIP switches as well? .. NO, I showed a picture of it and the DIP is ONLY on the 18v model, sorry!

And it should fit with drilling another hole for the mid pot/board? Right? .. For the 9v unit only. The 18v unit probably will not fit.

Also, what frequencies are available for the mid DIP switches? 200hz to 800hz? .. I don't remember exactly as it's been almost 10 years since I chose the frequencies. The Mid boosts and Cuts. I don't think is goes down to 200, that's more of a Bass frequency. It probably starts a bit higher and ends maybe 700-900 but I would have to go back and look up all the notes. I go by sound, not by numbers when I choose a sound, sorry. Regardless, you probably can't put this circuit in your bass any way without major surgery. The 18v model circuit is standard on all regular hand-made Smith USA basses since about 2004.

Ok, thanks for the info Ken.

Hey Greg,
I have the BMT 18V on my GN5 and the BMT 9V on my EG6. I really feel the difference is subtle. I would just drop in the Mid board IF I felt I miss anything. I wouldn't go through routing the bass just for the DIP switches and extra battery. My opinion.
