Breadboard Baker
Hey All,
I recently dipped my toe into the wonderful world of BASS and so far I'm loving it. Since we are all DIY'ers here to some degree or another I thought I would document my journey to build a fuzz pedal specifically for Bass. I started this on a breadboard with a BLEND control between a Bazz Fuss and raw input signal. Although it worked I wanted the raw signal to be louder since the fuzz overpowered everything before I got past 9 o'clock on the blend knob.
Oh! I should also mention I don't have a bass amp yet. Just using my regular 2x12 cab and keeping the volume relatively low. I know I need an amp and maybe I'll pull the trigger on that soon: nothing fancy or big. I am a bedroom player after all
The next step was to make the raw signal louder. Being the novice circuit designer that I am I decided to whip up an LPB-1 to boost the raw signal with 1uf in/out caps. Although the booster acted as it should I was having BLEND problems. I upped the blend pot all the way to 1m and was still getting bleedthough when the knob was at both extremes. That's when I opened up a troubleshooting forum here and got pointed in the right direction.
Here were the requirements I wanted for this build:
-Make the input signal louder
-Add a fuzz circuit in parallel
-Have a BLEND knob to mix between the two. No signal bleed should happen at either extreme
-Unity volume for the two parallel circuits
-Little to no noise/oscillation
So, @phi1 suggested a JMK Panner circuit to act as my blender. It's nothing more than an input and output buffer with a PAN/BLEND control in an effects loop. This was a great idea to start out with.
@Feral Feline made some good suggestions and gave me the ah-ha! moment: I need to design a BASS circuit, not a guitar circuit. The LPB-1 should be thrown out and he suggested the Mole/Hog's Foot circuit as the boost portion since it's specifically designed for bass. I'll put this one on the back burner for now if I need to come back to it.
For now, I've got a good idea what I want and will share the next step in my journey...

A Bleeding Blend Control on Bass
Hey Guys, Since I got my bass last week I wanted to put together a simple little circuit for it, and I'm currently in the breadboard phase. At first I wanted to do a Bazz Fuss with large in/out caps with a simple volume control. Then I realized it would sound better to allow some of the raw...
