El_JimBob Posted October 19, 2016 Share Posted October 19, 2016 [quote name='Beer of the Bass' timestamp='1476872253' post='3157905'] Have you seen Albert Kreuzer's design for an onboard preamp? It's a nicely thought out FET preamp with a single knob tone control. It's a shame there doesn't seem to be be any commercial preamps with this topology, as it would also suit the OP's requirements nicely. www.albertkreuzer.com/preamp_onboard.htm [/quote] It's the circuit that eventually became the Electronix Submarine preamp. Are they still manufactured? Quote Link to comment Share on other sites More sharing options...

Unfortunately, he stopped trading, and they are only available second hand, if you can find them. Quote Link to comment Share on other sites More sharing options...

It (along with Albert Kreuzer's rack preamp) has been on my to do list for YEARS. It was the basis for the idea. Kreuzer's preamp is the basis for the Fuzzrocious BDPG (with a modded LPB1 pushing the input) and Zeibek Submarine preamp. Quote Link to comment Share on other sites More sharing options...

ead Posted October 19, 2016 Share Posted October 19, 2016 [quote name='Roland Rock' timestamp='1476857516' post='3157761'] Why would a P need a blend? I thought the stacked knobs on the P Retro did the following: 1: Top - volume (pull for active mode) Bottom - passive tone 2: Top - mid boost one way,bass&treble boost the other way Bottom - variable frequency [/quote] Absolutely correct, major brain fart there.

drTStingray Posted October 19, 2016 Share Posted October 19, 2016 [quote name='fretmeister' timestamp='1476816624' post='3157573'] That post could be the very definition of false equivalence. [/quote] FWIW not really - the development of active basses (from early 70s) was a direct result of striving for better sound reproduction and mirrored other contemporary developments in the same field (SS amps, hi fi systems, better recording techniques. Bear in mind it was quite a quick gestation to get to the Wal type of bass with filter preamp (also Alembic) and for the mass market, the Stingray.

[/quote]Could you explain why your comment seemed more relevant to what Donald Trump has between his ears, than a sensible discussion on bass electronics?
