I use my 57 twin with a rec tube pulled & love the tone. I don't want to use an overdrive pedal so I want to leave everything as is. My question is, I want to add a leslie pedal HK rotosphere or a boss rt20 & need to know how its going to sound in front of the 57 twin? There is no effects loop so it will be before the breakup, will that work or will it sound like crap??
