A friend of mine asked me to fix his '"Locobox" Analog Delay' and a 'Ibanez TS9DX Turbo Tube Screamer'. I rarely come across pedals I haven't already heard of but the "Locobox" brand is all new to me. It's apparently a somewhat obscure Japanese brand. This particular model is probably 1970's vintage. I just might trace the circuit but I'm already pretty sure it'll be very close, if not identical to other Japanese brands from the era. We'll see.
