vintage Japanese preamp & digi tape echo
This classic 301 analog Japanese preamp & ambient Tape Echo simulator circuit is a unique circuit design thar started out as a single preamp pedal ( Dynobrain & Atomic Brain ) in 2008 and was morphed into a full Tape echo simulator in early 2017.
We designed its spacial echo side around a PT2399 chip with an analog delay circuit that loves to be pushed into saturation. Some folks call this Setzer-in-box or the all in one #rockabilly pedal, you make the call. Its all here powered by a 9v power supply(not incl) that only used 85mA max.
A re-301 input preamp (based on vintage roland) plus an echoplex pre* w analog photocell vibrato actually in the tape echo repeats w an adjustable EP preamp* on the front of the echo circuit, plus a preamp gain booster. Even added an FX loop insert for your favorite overdrive (like the Nocturne DC Fluid Drive) or vintage reverb (Nocturne El Pescadoro)
