I bought a 1983 Marshall 4010 combo amp some one put a mojotone FX loop ver3 in it, it works, but when you turn it from bypass to on there is a very loud pop and the volume increases quite a bit with nothing even plugged into it, is that normal? I changed the power tubes last night and took some photos maybe some one can see if it looks like its wired right or not. their are basically the 2 sets of twisted wire going to the master volume and 2 little white wires goes to the board and the other to a speaker jack. any help would be appreciated. it just worries me it's such a loud pop. Thank you
