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. Download and fill out the RonSound Repair Form
(PDF format), print and place in the box with your pedal.
