Boss HF-2 Hi Band Flanger Modifications
$ 49.95
Big, throbbing flange from a wimpy stock pedal. The HF-2 Hi-Band Flanger has loads of potential, but stock it's muddy, thin, and wimpy. This Fromel Supreme kit unleashes robust analog flange while keeping the clarity and warmth of your original tone — everything from subtle filtered flavors to psychotic swirling madness. Finished, it rivals any boutique flanger on the market.

What the kit does (full breakdown)
Goodbye metallic harshness — Fine-tunes the resonance and manual controls for smooth, fat analog flanging.
Fuller tone — Both signal-path op-amps are replaced with socketed high-quality audio op-amps, so your guitar's natural tone is preserved instead of lost in the wash.
Lower noise — All the cheap electrolytic caps are swapped for high-quality film caps, and upgraded power-supply caps allow up to 18V for more clean headroom.
Faster & deeper — The LFO is fine-tuned for higher maximum speed and greater maximum depth, with all the slow speeds left intact.
Know your speed — A special dual LED glows red in time with the Rate knob when bypassed, and turns blue when the effect is engaged.
Vintage flanging — Parts and instructions are included to voice the HF-2 close to the vintage MXR flanger.
PSA power supply — Converts the pedal from the old Boss ACA adapter to the standard PSA adapter.
Which option should I order?

Hear it
Installing the kit yourself voids the pedal's warranty and is done at your own risk — but with basic soldering skills and the included instructions, it's an easy project. International orders may take 4+ weeks due to customs.
