Power only by 9 Volt battery (in the pedals).
Between 1 + 1 output faade.
Quality of manufacture proper (change crmaillre).
PDAL plutt stable ground.
Amplitude running correctly.
As is often the case, the AWV-100 Whereas the increases in AIGS Wha.
Volume (not always supported by dclencher empty) is basic.
Not wanting to break the piggy bank for a U.S. colleague or Cry, I find the AWV-100 for a good quality for money (which I do not remember). I have over ten years, the little utilisanr (AIGS too!). Never had a problem.
I just bought the Boss PW-10. Y no contest as they say!
