Which single channel marshall will yield the biggest roundest clean tone and take pedals well. I am on an amp quest. I have a 50 watt marshall clone that sounds fine for a crunchy rock'n tone. I have a carr slant6 that has very good fender type tone. What I am looking for is an amp that will give me that really nice round clean tone ala, little wing, hey joe but will take my dirt pedals well. what do you think? jtm 45? 1959slp?
