hello every one im glad i found this great site.Im sure the van halen sound has been talked about alot and i just want to share this with you.In the early to mid 80s i use to speak to jose arredondo on a monthly basis we would talk about amps and different types of tone. Joses shop was called arreco electronics.I asked jose about van halens sound and i asked im about modding a marshall for me to achieve the van halen 1 sound off the first album and to my surprise and i quote jose he said that on the first album i did not do any mods at all he said to me that ED did use a distortion pedal in front of the marshall jose was not sure which distortion pedal he used. Jose did say to me that on the second album VHII he did start doing mods for ED and on his main plexi marshall.Im sure we all can here the difference between VHI sound and VHII sound. To me the VHI sound is much more edgy and in your face then VHII. VHII sounds less edgy like something was takin away. Any way i wanted to share this with you and i thank you for your time.
