Deluge Bass Distortion

Spotted this over at General Guitar Gadgets and thought it sounded nice. It's a modified
big muff that supposed to be tuned for bass, and from the clip it sounds pretty nice, but then again how can you go wrong with anything with big muff origins.

Baja ENG Overdrive

Bajaman's overdrive circuit based on the Engl 530 preamp with switchable tone stack.
Original thread and schematic available on the FSB forum here.
The layout should fit in a 125B box.

09/07/2018 Layout Updated! Inverted Treble and Bass pots' lugs. Changed 390p cap from TL062 pin 5 to 470p. Changed 1K resistor next to 22uF cap to 1K5.
22K resistor between Gain 1 and Gain 3 goes from Gain 1 to 15n/10K 3 rows below instead of Gain 3. 22K above TL062 pin 8 needs to move down one row between 10K/22K and VBias.

Baja MDR Overdrive

Bajaman's overdrive/distortion circuit based on the Mesa Dual Rectifier high gain channel with switchable tone stack.
Original thread and schematic available on the FSB forum here.

Baja Highway 1

Bajaman's overdrive/distortion circuit based on a modified Boss DS-1 with an active high and low tone control section.
Original thread and schematic available on the FSB forum here.
The layout should fit in a 1590B box.

Baja JVM Overdrive

This is based on a Marshall JVM410.
You can find Bajaman's original thread and schematic on the FSB forum here.
There are two versions:
First one with just one toggle switch to select between Cruch, OD1 and OD2.
The second one uses separate footswitches, Gains and Levels.
You need to add an extra pole for LEDs.
Can use any small signal N channel JFet for the buffers (mind the pinout).

Laney Supergroup 100 MkI Preamp

Laney Supergroup 100 MkI

What can I say about the Laney Supergroup. The supergroup was based on the same Fender Bassman architecture just like the Marshall JCM800, Sunn Model T, Mesa Dual Rectifier, and a whole host of other legendary Rock, Hard Rock, and Metal amplifiers. One of the best descriptions I've ever heard of the Supergroup is that it's like a Marshall JCM800 with more balls and gain. It's just an all around badass heavy amp. And for all my lovers of tall things heavy it was used by the legendary Tony Iommi for years, and Laney even went through the trouble of recreating it to reissue it as a special signature amp for Iommi.
