Here's my review of the Echoes pickups set from D Allen. The set feature neck and middle 69 Voodoo's (5.8k) and a custom "dual" bridge pickup, with a push/push mechanism, delivering classic low output late 60s tones (7.6k) and a hotter, more modern sounding tone in the second position (12.5k). Designed to capture over 4 decades of David Gilmour's Black Strat tones, the Echoes is an incredibly versatile pickup set.
