At [sfx] we can modify your pedals to achieve the sound and the functionalities you want.

We can extend the frequency response for bass guitar, change the input impedance (e.g. for piezo pickups) or add switching controls.


These are just some examples of the mods that we can implement:

Catalinbread HypePak mods Bass extension
ProCo Rat and Turbo Rat mods Bass extension
EMMA Discumbobulator mods External switching for up/down toggle switch
EHX Micro Synthesizer mods True Bypass
