4 in 1 Pedal: Distortion, Delay, Headphone Jack and AUX in
Decent Pedal, no SMT technology. Not as flexable but better sound then many digital modeler units.
There is a 5448 opamp and the delay comes from a PT2399. A True Bypass 3pdt switch.
Plug your smartphone into the AUX jack, add distortion, delay, connect headphones to the headphone jack and rock.
