Review: Excellent power unit for FX pedals - Excellent power unit, works well with the Ditto x2 looper, No hum at all when connected and in use, tough enough to withstand gig use as its well constructed. The red colour makes it easy to find in the gig case and more important that's its the correct power unit for my looper or other pedals. Don't buy cheap as I have done in the past, you only get what you pay for. I can recommend this. Review: Excellent psu. The one to buy. - This is an excellent psu. I've bought several RAAD psu for my pedals. They're very low noise and reliable. I've found them perfect. I think they possibly use some old school electronics inside that lend themselves to low noise and long life. I always buy the highest rated current version so there's less risk of over-heat or volt-drop. Great price too. ## Features - Regulated Class 2 Transformer - Super quiet hum and squeal free design. - Designed in England! - Takes only one spot on the power plug - 12 month warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00E404R2E | | Colour | Red | | Customer Reviews | 4.3 4.3 out of 5 stars (22) | | Date First Available | 22 July 2013 | | Item Weight | 345 g | | Item model number | RAAD | | Product Dimensions | 5.99 x 5 x 5 cm; 344.73 g | ## Images ![RAAD regulated DC 9V AC/DC power supply adaptor tip negative center class 2 transformer replacement for boss PSA-230 PSA-240 (500mA) - Image 1](https://m.media-amazon.com/images/I/41jPhyX6rPL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent power unit for FX pedals *by M***K on 20 January 2016* Excellent power unit, works well with the Ditto x2 looper, No hum at all when connected and in use, tough enough to withstand gig use as its well constructed.
