The sharpshooter !
I designed another Peavey bass preamp PCB. The Century B or Century 200H (due to the power module) .
Even though I get better with PCB design I am not anywhere near disssa who has taken on a similar project before (link). But I am glad my designs work
Since I have built quite a few of those units that run on bipolar voltage, this time I decided to built the unit without a DC converter, but rather have a 4-pin GX connector to share power between units. Worked out nicely !
Similarly to disssa, I also had to put together my own potentiometers for this strange value. I used a Dual gang linear 10K, removed the top gang and replaced it with Anti-log 1k. it was a matter of trial and error until I found the pots that matched but it eventually worked.
The preamp itself is super versatile with parametric mids and switchable Saturation control. Low saturation settings have an overdrive-y marshally tone if you tune the parametric mids properly but past mid-way it has a fuzzier character with typical compressed sound.
Lastly, I designed and snugged in a parallel buffer/ three channel mixer that also runs on bipolar voltage. The schematic is based on the PedalPCBs three channel splitter and mixer. Channel 3 is the Sharpshooter, two more channels can be combined and their phases can be inverted if needed. I used stereo jacks for the send-return of each channel. Here's the schematic for this buffer/splitter/inverter/3 channel parallel mixer that runs on bipolar 15V. I called it Kanye Zest, another greek pun.
Quite stuffed for such an enclosure, hence this spaghetti-mess but the unit is super quiet, well, until you turn that big fat red Saturation knob up. Then it’s sonic mayhem
.
Super satisfied with this build.
