“Technically speaking, the pedals can be in any order. The order that provides you with the tone and effect that you like is always the correct order. That being said there is a commonly used order that most adhere to, and for good reason.
The following is a general rule of thumb to go by.
1. MICROPHONE (Low impedance mics require an impedance matching transformer)
2. ANTI-FEEDBACK DEVICES – Such as the Harp Shield and the Kinder anti-feedback pedal
3. TONE SHAPING PEDALS – Harp Tone+, an EQ pedal
4. BODY ADDING PEDALS – Harp Chorus, Harp Octave, LoLoHi, POG
5. BOOST PEDALS – Typically a clean boost like the Clean Cat
6. DRIVE PEDALS – Harp Break, Harp Attack, Blues Driver
7. ROOM EFFECT – Harp Delay, Harp Reverb
8. STUDIO EFFECT – Clean compressors like the Flat Cat
9. INTERFACE, for one of the following amplifiers
For Guitar Amp – Mojo Pad
For PA – Little Red DI, or another DI Box
For Harp Amp – None”
