Hello, sorry for my english, i'm french. I hope to talk with you about my marshall class 5, if you'r agree? I have mod my Class 5 (lyle caldwell procédure) and i've put a Classictone 15w OT and a Tayden True Brit 25w speaker. Sounds good, but, treble are too present (i play with a vintage telecaster v52). Any way to reduce treble influence? Thank you very much!
