Getting tired of the sound your new Lil Big Muff Pi, black Sovtek Big Muff or reissue EH Big Muff gives you?

For less than the price of a new pedal you can have them modded to any of the RonSound Hairpie specs: Classic, '75, or '81 version, you call the shots!
All mods include a new BOSS-style AC adapter jack (mounted in place of the original jack on the US reissue).

Add $15 for a new footswitch for true-bypass and LED indicator. Check your pedal first: if it's got a blue footswitch, you're already good to go there!

Note: To order, please add the mod to your cart and checkout as usual. Requires shipping your pedal to me for modification. Request a repair form and shipping address with your order.
