erp.... coming from a guy who owned a peavey windsor..... they DO NOT take pedals well...... at all

i tried to use both an MXR distortion+ clone, and a Big Muff PI in front of the amp and both had the same effect, destroyed the bass. and added more noise than distortion........ sadly the best distortion a windsor gets is what it has, even a clean boost just boosts noise and doesn't change the distortion character, it just adds saturation to the distortion tone it already has......

if you are looking for a more metal tone an MT-2 will help.... if you are just looking for more gain in the same style the amp has on it's own, change the tubes to JJ's that helps ALOT.

my recommendation is swap out the stock tubes (ruby power tubes) for JJ E34Ls, the pre-amp tubes should already be JJs
