Here's a delay pedal project at the request of a talented bass pal from the BassChat forum; This is Sonic Kitchen's Time Machine.
PCB from tonepad.com, circuit modified with send-return loop and an op-amp buffer.
Only the delay signal gets routed thru the send-return loop so you can apply quite a subtle effect or a deeply shocking one to the repeats while still getting the clean dry signal pushing through first.
Here the completed circuit routed through the buffer is bveing readied for testing before boxing up.
Here's the finished pedal guts shot, this is about as close as I can get to neat and tidy

Found a sexy little indicator LED to install from ebay which is pre-wired to pulse though blue/gree/purple/orange and guaranteed to partially blind direct eye contact in a dark pub gig.
