hello,

a friend of mine owns a marshall mg30dfx amplifier. He is quite frustrated with the manual switching between clean and dirty in the middle of a song while he is playing something. so it would be a great help if some one can post the schematic for marshall 30dfx foot switch. any kind of idea is helpful for me..

 

thanks in advance

HELLO,

I am currently drawing pcb for rod's project 27mk2. there are few capacitors in the diagram greater than 1uf in non polar which are hard to find in small voltage. so i would like to replace them with electrolytic capacitors. i have edited that image in paint...please verify if their polarity are ok.
Thanks in advance...

Hello,

I am new to this site. actually I am trying to build a solid state guitar amp of marshall type. do marshall valvestate 8020,8040 worth trying? 8040 even have a tube. i never worked with tube. so 8040 is bit harder for me.

basically i need this: Guitar to amp(clean and distortion channel) --fx loop-- power amp. so i need to drop the reverb circuit.
