EFX RETURN

Prohibited no permission reprint

It is the effect return part.
The actually input circuit using also the semiconductor, seems that it unites, but, it is unclear.
NFB (negative feedback) it is feature to apply.
When negative feedback is applied, the distortion decreases, gain goes down.
As for the effect return it is not necessary to expand the signal, because the one where also the distortion is little is good it is thought the thing which applies negative feedback.

R40 3.3M Resistance for negative feedback. In just this schematic the negative feedback of some dB catches, it cannot calculate

R41 1.5k Resistance for cathode bias

R42 4.7M As for the switch when changing, resistance because C34 that tries does not float

C33 2200p Condenser for negative feedback. As for purpose DC cutting. The kind of air whose already a little large value is better does.

C34 22n Coupling capacitor. Fc is low

SW16 * The selector switch whether or not the bypass it does the [ehuekutosendoritan] circuit of,
