used  also  as a  power  amp  input  with 

line level (+4dB) or instrument level (-

alternative   preamplifier,   including   a 
simple stomp box.

Effects   loop   send   socket   with 

switchable   level.   Plugging   any   jack   in 
the   socket,   brakes   the   amplifier's 

internal   connection   between   preamp 
and   power   amp.   Therefore   it   can   be 

used  also  as a  power  amp  input  with 
line level (+4dB) or instrument level (-

10dB) signal, so you can plug here the
