Boss BF-2 Flanger Modifications

$ 21.95

The BF-2 Flanger circuit has loads of potential,but in it’s stock form it a pedal that’s muddy, thin and just plain wimpy sounding.However, the Fromel Supreme kit unleashes the robust, throbbing flange of the BF-2, while retaining the clarity and warmth of your original tone. In your pedal’s “born again” state, you can dial in everything from subtle filtered flavors to psychotic swirling madness!


Say Goodbye to Metallic Harshness – The supreme mod kit fine tunes the resonance and manual controls for smooth fat analog flanging.


Tired of the Thin tone – Both the op-amps in the signal path are replaced with socketed high quality audio op-amps. so your guitars natural tone will be preserved instead of being lost in a wash.


Eliminate Noise - The supreme mod kit replaces all the cheap electrolytic caps with high quality film caps so your tone is unrestricted and full of power.


Faster and Deeper – The LFO is fine tuned for faster maximum speed and deeper maximum depth, all the slow speeds are left intact.

Know your speed – A special dual LED will glow Red in time with the rate knob even when bypassed!! When the effect is engaged, the LED turns Blue and still glows red in time with the rate.

Vintage Flanging – You can tune the BF-2 to sound very similar to the vintage MXR flanger, parts and instructions are included for this option. 


PSA Power Supply – Many BF-2’s only work with the old style Boss ACA power adapter, the Supreme mod kit converts the pedal to run off the new standard Boss PSA power adapter.

This is a great mod kit and when complete will rival any boutique flanger on the market. Included are all the parts and detailed instructions with color photos to transform your BF-2.

NOTE: in 2017 Boss produces the some pedals with surface mount technology. This mod kit will not work on the new Boss pedals with a surface mount PCB. Review the image with this product listing for more information.
