I use this Dual Purpose Board for electric guitar and bass. The board is a Gator Case powered pedal board with G-Bus-8 power supply. It does 9v and 18v DC. The only factory stock pedal is the MXR Stereo Chorus which works great for bass and guitar. The Wah is a kit from BYOC. I modded it with pots for the Q and tone so it works great with Bass and Guitar. The OD2 is a DIY kit from BYOC. It's a clone of the Tube screamer 808, with the addition of a clean boost. It works great with the guitar and Bass as it has many adjustments for tone shaping. And the clean boost helps with passive signals when using the other effects. The EF 440 is a General Gadgets Kit of the DOD 440 Envelope Filter: It works great for guitar when using the boost, but it sound weak and thin with the bass guitar.
