Right now I am totally in love with the sound of my Fender Hot Rod Deluxe. Unfortunately I only get to crank it up about once a month. This amp has beautiful tone, it need absolutely no effect what-so-ever.
My second most favorite toy it the Digitech RP300A. I user more than anything esle. It sounds best through headphones. It doesn't sound too hot through an amplifier. It works OK plugged directly into a sound board though.
Stayed tuned for my thoughtful insights.
