My current most important five pedals.
1. Iron Ether Xerograph
My most important pedal. Static low pass filter, envelope filter, wah & autowah sounds, synthy sweeps and more. I've tried a ton of other filters and it has remained king of the mountain for six or seven years or so. The next challenger will be a Mu-Fx Micro-Tron
2. JohnK Foundry
A BJFE Blueberry Bass OD cascading into an Electronix Submarine. My favorite and the most versatile overdrive I've owned. On its own the Submarine is a simple and great sounding preamp.
3. 3Leaf Octabvre Mk II
I've gone back and forth between this and the Aguilar Octamizer. Very different but both great sounding and versatile analog octavers.
4. Origin Effects Cali76 Compact Bass
The only comp I've liked as much was my Retrospec Squeezebox and the Cali76 CB is a fraction of the size and is powered off a standard 9V power supply. Great compressor.
5. Earthquaker Dispatch Master
I've tried to go to separate reverb and delay but this one is just easy to use, sounds great and does both jobs well while only taking up one spot on my board. I love it for fretless and ambient or synthy sounds.
I could name a hundred runners-up from over the years but the only other pedals I'm currently using are: TAFM, Bad Stone, Polytope, Subterranea, Turbo Tuner, and Prunes & Custard.
