Baja AFD MkII
Gotten a couple requests for this one. Here’s Bajaman’s second take at his AFD circuit with a better frequency response than the first AFD. More info here on FSB. Should fit nicely in a 1590B.
Baja Reactor
This one was requested ages ago and I got halfway through laying it out, and then promptly forgot about it. It’s a power amp/speaker cabinet simulator, emulating a SLO power amp and a couple different speaker cabinets based on the value used for CX (see schematic for values). This layout follows the Rev4 schematic from the … Read more
Baja Optical Limiter
Here’s one of Bajaman’s non-amp emulating circuits, the Optical Limiter. It’s based on the Demeter Compulator, but is not a compressor but a limiter. What’s the difference? The ratio is the main difference between a compressor and a limiter. A compressor has a low ratio that turns down SOME of the volume when it goes above the threshold. A limiter has a … Read more
Bajaman AC30 Normal Channel
Here’s Baja’s AC30 Normal Channel emulator. Throw a treble booster in front of this and you’re pretty darn close to nailing some Brian May tones. Schematic and discussion here on FSB.
Baja AC30TB Emulator
Another one of Bajaman’s many amp emulator circuits. It emulates the frequency response of the classic Vox AC30 top boost channel, including power amplifier emulation. It’s designed to fit in a 125B with top mounted jacks. Schematic and discussion on FSB here. The input buffer stage uses a 2SK117 JFET with DGS pinout, but I’ve … Read more
Baja Mars Hall 59 Plexi
Bajaman’s overdrive circuit based on the Marshall 59 Plexi amplifier. Original thread and schematic available on the FSB forum here.
Baja 59 Tweed Bassman
Bajaman’s overdrive circuit based on the Fender 59 Tweed Bassman amplifier. Original thread and schematic available on the FSB forum here.
Baja Ampeg SVT Bass Amplifier
Original FSB thread and schematic available here. I’ve put the Mid Freq switch components on a separate board to make it easier to box it.
Baja VH4
Another drive circuit from Bajaman. He’s been on a tear lately! In his words… Here is my latest build based on the frequency response characteristics of the Diezel VH4 tube head channels 3 and 4, but scaled down into a 9v dc pedal friendly format… I got a chance to try using it on Neil Young’s “Keep … Read more
