Hey all,
I had a DigiTech Screamin' Blues pedal I was literally using as a doorstop in my music room. After reading what Nebulozny and others were putting into their effects loops for master volume control I decided to drop in the Screamin' Blues pedal and I'll be damn if it didn't work like a champ. I can now crank my gain to about 2 or 3 o'clock and the master volume to 12 or 1 o'clock on the OD channel while controlling the final volume with the Screamin' Blues pedal. Now, I REALLY like the MA50H. I'm with everybody else, Marshalls have to be cranked to get "that tone" and the MA series is no exception. Don't know why people dog this line other than they're not made in the UK. Well......get over it Can't beat it for the price.
With higher gain and higher volumes comes the problem of hiss, at least with my amp head anyway. I have new preamp tubes on the way that I hope will solve or partially solve this issue.
