I like using my Sadowsky stomp box pre amp, and bypassing the front end of my 800RB. BUT! My Fodera pre, has much more output than the Sadowsky, and can easily run my 800 RB. The Sadowsky has much less output, so its not very loud. How can i get more output from the Sadowsky? Is there a way to raise the output gain, or put something in line to stengthen the signal?? Or what?
