The great thing about this pedal is that it uses a standard negative center 9 volt power supply. DO NOT USE A POWER SUPPLY HIGHER THAN ( VOLTS! It has an internal voltage converter that supplies the +15 and -15 volts required for the circuit. (the original Rusty box requires a 28-30 volt center positive supply). I used all high quality Wima capacitors and Lumberg jacks in this one.\u003c\/p\u003e\n\n\u003cp\u003eit's comes in a 1590BBS which has the same dimensions as a standard 1590BB but is a bit deeper to allow all of the components to fit.\u003c\/p\u003e","brand":"JohnK","offers":[{"title":"Default Title","offer_id":44204098093130,"sku":"REV-1789334800151","price":339.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/5451\/1434\/files\/product_3_photo_0_2f68522c-8f75-4b68-b268-b344394e02fe.jpg?v=1789337856","url":"https:\/\/lamusika.co.uk\/products\/johnk-traynor-ts50-b-preamp-pedal-2025-black-silver-rusty-box","provider":"LAMUSIKA","version":"1.0","type":"link"}
