Tweaker guitar amplifier, into effects loop I introduce Zoom G2.
Signal is attenuated significantly even with all modules bypassed and output of G2 cranked. With high gain Tweaker preamp setting I get digital clip, there are no indicators but I know that sound, oh how I know that sound. But well before clip, trouble too. Why?
Relevant specs:
Zoom G2
Rated Input Level -20dBm
Input Impedence 1 megaohm
Maximum Output Level +5dBm
(output load impedance 10 kilo ohms or more)
Tweaker
Effects Loop Send Impedance 600 ohms
Effects Loop Return Impedance 220 kilo ohms
Shed light, please.
