Rehousing a Behringer SF300 (Boss FZ-2 Hyper Fuzz Clone)

Here's how I moved my Behringer SF300 over into a metal enclosure.

The bypass remains buffered, using a momentary footswitch and off-board jacks for the audio and power. The pots and toggle switches are stock.


Rehousing Behringer pedals is a much-discussed topic in the pedal world, as their circuits are often affordable spot-on recreations of vintage / hard to find / expensive pedals, but the cost is brought down by the build quality. See the JHS Show vlog for more on that. After the HM300 (A pretty good HM-2 clone, but not perfect) the one that gets the highest praise for its sound is the SF300 – it's spot on. There is no difference. The bass response is there, it stacks well, the boost function is powerful as hell and Fuzz 2 instantly transports you to Dopethrone territory. Wonderful stuff. Rehousing it has always been a goal of mine as I like to screw around with cheap pedals, much more than I do buying vintage ones.


Important things to note:


Pay attention when wiring the power. Running reverse voltage through a circuit isn't a great idea (I fried another SF300 by screwing up here.)


If you do want to do offboard pots, it's 50Ka for the volume and gain and 50Kb for the bass/treble.


If I was to do this again, I might put the jacks/power supply underneath the PCB rather than between the PCB and the top of the case, as that might allow for top-mounted jacks / give more clearance on the shafts for knobs. Hee hee.


As there's not a full written guide anywhere as far as I can tell, is that something you'd be interested in? Let me know and I can put one together.
